I was just in walmart hoping to find 0w, but they didnt have it. Around here all the Mobil 1 grades 0W, 0W, 0W, etc are the same exact price. Only the Extended Performance costs more, and I really don't see what you gain from that stuff For example, if you want "better" protection. Our winters can dip toand I want the proven low temp performance. I've had good used oil lab results running the 0W to 16, km Recently, Mobil decided to start publishing MRV data on their M1 products.
About time. I've used it before and it holds up very well.
Oil Labelling Explained
There are obvious advantages to using the 0W in temps below F. The 0W will work well for you I keep careful log of fuel consumption, from Spring to Fall there is no readily apparent difference in fuel consumption between the 0W and 0W Rest Active Member. If you are under warranty be warned Toyota will not cover the engine should there be a problem and they find out you used a 0W oil.
It is not approved for the newer model Prius. At least not in the States. NoMoShocks Electrical Engineer. Why not use the 5W recommended by Toyota? Does Mobile1 have that combination? Since these are multi viscosity oils, if you get a larger range like 0W, it seems to me you will end up with a smaller percentage of the total volume of oil being in the recommended optimal 5W range.
I would much rather use a superior synthetic over the garbage they use at the dealer. I have read this thread in its entirety and am not sure I understand it all or can draw a conclusion. I would like to use synthetic oil in my first oil change I intend to use a Toyota filter and Mobil 1.What does 0w 20 oil mean?
The W actually stands for "winter" but basically means "viscosity when cold. Motor oil. See Full Answer. What kind of oil is SAE 0w 20? How long does OW 20 motor oil last? A: Toyota models that require synthetic oil have this statement in the Owner's Manual: "SAE OW is the best choice for good fuel economy and good starting in cold weather. If you're nervous about going 10, miles or more between oil changes, then do it every six months, when you probably should also have your tires rotated also explained in your owner's manual.
GM says to change your oil at least once a year even if the service indicator warning light doesn't come on. Oil can be very, very dark black even and still be effective.
However, as a general rule: New, clean oil is amber in color. As engine oil gets darker, it can indicate a high heat, b contaminants, or c the presence of additives that cause the oil to darken during normal use.
Generally speaking, synthetic blends and semi- synthetic refer to the same thing: an oil that uses a combination of conventional and synthetic base oils in its formulation. How many miles does 0w20 oil last? The longest oil change interval is 15, miles for all Jaguar vehicles. The shortest oil change interval is 5, miles in some Hyundai and Kia models with turbo engines and Toyota vehicles that call for non-synthetic oil.
Toyota has been shifting its fleet to 10, -mile oil change intervals using synthetic oil. Six Months or 10, to 15, miles. Most synthetic oils, such as Castrol, are rated to last between 10, and 15, miles or six months. These ratings are only recommendations typically applied to "normal driving," and do not reflect severe driving conditions that may require more-frequent oil changes.
Mazda3 oil change schedule. Mazda recommends that you change the oil in your Mazda3 every 6 months or 7, miles, whichever comes first. You should never, under any circumstances, drive for more than 12 months or 10, miles without changing your Mazda3's oilas that can be very harmful to the vehicle.
Unless you want to see your mechanic every two monthsa 3,mile oil change interval is another extreme.Motor oil is defined as a substance added with the various amount of additives with are used as lubrication for internal combustion engines. The sole purpose of motor oil is to reduce wear and tear, and friction from the every moving part of an engine.
One of the important ingredients in motor oil is detergents because it improves the piston sealing and helps to cool the engine by diverting heat from the moving parts. Motor oil is mostly used to power all forms of machinery which includes lawn mowers, cars, generators, motorcycles, and many other machines.
It functions in various capacities in the engine such as reducing wear in engines, lubricating the moving areas, making the engine parts cool, etc. It is highly essential to the lifespan of every engine. Every time your engine is in motion, residue from the combustion engines tend to adulterate your engine, and when there is an accumulation of this residue, they can create dirt and filthy deposits in the engine.
Also, the failure to look after your engine by changing the oil can lead to negative issues with your engine, and when the components of the engine are dirty, the efficiency, longevity, and speed of your vehicle can degrade. Motor oil consists of various types, brands, price, etc. But the most important ones we are going to take note of is the 0W and the 5W motor oil. What makes these oils unique? What brands will people go for? Where can they be used?
In this article, we will highlight the differences between these two popular oils. These oils are mostly known as low viscosity oil, and this particular oil type is becoming very common amongst popular buyers in the market because it is said to deliver the best performance.
It readily means that the 0 oil will flow well and better at a cold temperature more than 5W oils even while maintaining the same viscosity. The 0W is said to be the best oil in the market because it helps to reduce environment hassle on waste oil disposal. The 0 before the W on the label is referred to as the viscosity of the oil when the engine is cold.
The 20 at the end represents the viscosity of the oil at a higher temperature according to the Society of Automotive Engineers.
The lower the number, the thinner the viscosity of the oil. THE 0W oil is also commonly referred to as the multi-viscosity oil because it contains a certain amount of special additives to make it have different viscosities when cold.
Temperatures and certain climate conditions affect the use of 0W over the 5W engine oil. Putting the 5W in summer seasons will cause the oil to be thinner leading to damage in the long run. Every day, thousands of cars in factories are replaced with 0W synthetic engine oil for improved overall engine performance and improved environmental conditions in a world where the rate of pollution always seems to be escalating. There are very minimal losses in the oil especially when it is cold due to its low viscosity of the oil.
Most times, 0W synthetic oil can be more expensive than the 5W, spending that extra cash for the lifespan of your vehicle can turn out to be a very worth-while investment. The 5W motor oil is another very good and highly efficient motor oil.
It is an overall preparation that can function in environments where there are extreme colds and extreme heat. The 5W engine oil assures every machine user of good start-up and good low-temperature protection. In a 5W for example, 5 represents the viscosity of the oil at a low temperature of 5 degrees Celsius. The more the number decreases, the better the cold start temperature and the thinner the motor oil will be.
W represents winter, and the number 30 describes how thick the oil will be at the operating temperature of the engine.
Motors oils like this 5W are also very widely used and most times general accepted by machine users especially car users instead of the 0W is that they can function very well in all but highly extreme cold and hot temperatures. Some people prefer the 5W motor oil to 0W motor oil because of certain places with warm winters and the ready availability of the motor oil.
Although it occasionally seems like the OW motor oils are on the top of the chain when it comes to efficient motor oil because most vehicles, those already in use and those that are still with the manufacturers tend to always recommend 0w motor oil for their machinery. Nevertheless, the popularity of the 5W motor oil is slowly gaining momentum because it tends to adapt properly to a range of weather conditions, especially during the warm winter seasons.
The 5W oil is a very good multi-grade oil for low starting temperatures as well as high summer temperatures. More so, it is highly fuel-efficient creating less drag on the moving engine parts.In terms of taking care of your car, there's not much more important than changing oil.
The reason 5W and 5W motor oils are so common is because they work very well with a wide range of engines. Most often, these types of oils best cover the range of possible temperatures, with a 5W oil more geared toward colder climates and a 5W oil more appropriate for warmer temperature extremes. For the most part, either one should work just fine in an engine regardless of the prevailing temperatures.
The main difference between 5W and 5W motor oil is that the latter is less viscous or thick. When used in a vehicle's engine, 5W oil creates less friction due to its thinner viscosity, meaning it causes less drag across engine parts like the crankshaft, valvetrain, and pistons.
This can provide a slight bump in fuel efficiency. The thinner nature of 5W oil also allows the oil pump to move it from the oil pan to the rest of the engine more easily. This makes 5W preferable for very cold climates, when having thinner oil that can flow easily on start-up is important. Where 5W comes into play is in hotter climates where thin oil tends to break down under higher temperatures.
This translates into the strength of the 5W oil keeping it from breaking down as quickly as the 5W oil, providing better overall engine part protection. Designed to operate in a multitude of temperature ranges, a multiviscosity oil represents one of the best motor oils for cars.
The single viscosity oils of the past provided protection during either hot or cold weather, depending in large part on the weight, or lower temperature extreme at which they operated.
This usually meant using a 5W oil in the fall and winter and a 10W in the spring and summer. A multiviscosity oil, on the other hand, uses special additives to improve the viscosity of the oil. Called, ironically, viscosity improvers, these additives expand as the oil heats up, providing a higher viscosity at warmer temperatures. After the oil cools, these improvers shrink, making the oil thinner, best for use during cooler engine operation.
Oil manufacturers use additives in oil for cars to improve the performance of the oil when it comes to lubrication. In addition, some other affects of additives in oils include cleaning engine deposits from engine parts, inhibiting corrosion or rust inside the engine, and keep the oil from breaking down as bad either due to oxidation or extreme temperatures. When looking for a motor oil that works best in your vehicle, keep certain factors in mind.
While not a lot of difference exists between the protection provided by a 5W AND 5W oil, there is a slight difference in the viscosity levels of each. The thicker 5W should see a slight advantage when operating at higher temperatures, while the thinner 5W oil should provide better engine protection at lower temperature levels and has the added benefit of slightly improving fuel efficiency. The flexibility of today's synthetic motor oil means that both 5W and 5W oils work equally well to protect your engine regardless of the climate or season.

How Does Oil Lubricate an Engine?Motor oilengine oilor engine lubricant is any of various substances comprising base oils enhanced with various additives, particularly antiwear additive in addition to detergents, dispersants and, for multi-grade oils, viscosity index improvers. Motor oil is used for lubrication of internal combustion engines. The main function of motor oil is to reduce friction and wear on moving parts and to clean the engine from sludge one of the functions of dispersants and varnish detergents.
It also neutralizes acids that originate from fuel and from oxidation of the lubricant detergentsimproves sealing of piston rings, and cools the engine by carrying heat away from moving parts. In addition to the aforementioned basic constituents, almost all lubricating oils contain corrosion and oxidation inhibitors. Motor oil may be composed of only a lubricant base stock in the case of non- detergent oil, or a lubricant base stock plus additives to improve the oil's detergency, extreme pressure performance, and ability to inhibit corrosion of engine parts.
While studying the possible healing powers of crude oil, Dr. Ellis was disappointed to find no real medicinal value, but was intrigued by its potential lubricating properties. He eventually abandoned the medical practice to devote his time to the development of an all-petroleum, high viscosity lubricant for steam engines — then using inefficient combinations of petroleum and animal and vegetable fats.
He made his breakthrough when he developed an oil that worked effectively in high temperatures. This meant no more gummed valves, corroded cylinders or leaking seals. Motor oil is a lubricant used in internal combustion engines, which power carsmotorcycleslawnmowersengine-generatorsand many other machines.
In engines, there are parts which move against each other, and the friction wastes otherwise useful power by converting the kinetic energy to heat. It also wears away those parts, which could lead to lower efficiency and degradation of the engine. This increases fuel consumption and decreases power output and can lead to engine failure. Lubricating oil creates a separating film between surfaces of adjacent moving parts to minimize direct contact between them, decreasing heat caused by friction and reducing wear, thus protecting the engine.
In use, motor oil transfers heat through conduction as it flows through the engine. While modern recirculating pumps are typically provided in passenger cars and other engines similar or larger in size, total loss oiling is a design option that remains popular in small and miniature engines. Motor oils with higher viscosity indices thin less at these higher temperatures. Coating metal parts with oil also keeps them from being exposed to oxygeninhibiting oxidation at elevated operating temperatures preventing rust or corrosion.
Corrosion inhibitors may also be added to the motor oil. Many motor oils also have detergents and dispersants added to help keep the engine clean and minimize oil sludge build-up. The oil is able to trap soot from combustion in itself, rather than leaving it deposited on the internal surfaces.
It is a combination of this and some singeing that turns used oil black after some running. Rubbing of metal engine parts inevitably produces some microscopic metallic particles from the wearing of the surfaces. Such particles could circulate in the oil and grind against moving parts, causing wear.
Because particles accumulate in the oil, it is typically circulated through an oil filter to remove harmful particles. An oil pumpa vane or gear pump powered by the engine, pumps the oil throughout the engine, including the oil filter. Oil filters can be a full flow or bypass type.
In the crankcase of a vehicle engine, motor oil lubricates rotating or sliding surfaces between the crankshaft journal bearings main bearings and big-end bearings and rods connecting the pistons to the crankshaft. The oil collects in an oil panor sumpat the bottom of the crankcase.
In some small engines such as lawn mower engines, dippers on the bottoms of connecting rods dip into the oil at the bottom and splash it around the crankcase as needed to lubricate parts inside. In modern vehicle engines, the oil pump takes oil from the oil pan and sends it through the oil filter into oil galleries, from which the oil lubricates the main bearings holding the crankshaft up at the main journals and camshaft bearings operating the valves.Most of the time when viscosity is explained words are used that are too technical for the average person to quickly grasp.
This leaves them still wondering what the viscosity numbers really mean on a bottle of motor oil. Simply put, viscosity is the oil's resistance to flow or, for the layman, an oil's speed of flow as measured through a device known as a viscometer.
ENGINE OIL VISCOSITY GRADES
The thicker higher viscosity of an oil, the slower it will flow. You will see oil viscosity measurement in lube articles stated in kinematic kv and absolute cSt terms.
These are translated into the easier to understand SAE viscosity numbers you see on an oil bottle. What does a 5W do that an SAE 30 won't? When you see a W on a viscosity rating it means that this oil viscosity has been tested at a Colder temperature.
The difference is when the viscosity is tested at a much colder temperature. This allows the engine to get quick oil flow when it is started cold verses dry running until lubricant either warms up sufficiently or is finally forced through the engine oil system. The advantages of a low W viscosity number is obvious. The quicker the oil flows cold, the less dry running. Less dry running means much less engine wear. Obviously, cold temperature or W ratings are tested differently than regular SAE viscosity ratings.
Simply put, these tests are done with a different temperature system. There is a scale for the Wor winter viscosity grades and, depending on which grade is selected, testing is done at different temperatures. See the Tables to the right below for more information. Using a table they determine SAE viscosity based on different ranges.
Thicker or heavy viscosity oils will take longer to flow through the orifice in the viscometer and end up in higher number ranges such as SAE 50 or SAE 60 for example. Occasionally it is possible for an oil to barely fall into one viscosity range. For example, an oil is barely an SAE 30 having a time that puts it on the very low side. Technically speaking these oils will be close to the same viscosity even though one is an SAE 20 and the other an SAE But you have to draw the line somewhere and that's how the SAE system is designed.
Another system takes more accurate numbers into account known as cSt abbreviated for centistokes. You'll see these numbers used often for industrial lubricants such as compressor or hydraulic oils. You'll see the ranges for cSt compared to SAE numbers. An oil that is 9. This is why the cSt centistokes numbers more accurately show oil viscosity. Now if you look at the table labeled Winter or "W" Gradesyou can get valuable information on how the W or winter grade viscosities are measured.
Basically, as shown by the chart, when the oil is reduced to a colder temperature it is measured for performance factors.0W-16, 0W-8: The Thinning of Motor Oils • Carmunity Discussion
Consequently, if the motor oil performs like a SAE 20 motor oil at the reduced temperatures the scale varies - see the chartthen it will be a SAE 20W motor oil.
Getting the picture?I recently got a car Camry which calls for 0W oil. How can I think about this? Well, 0w20 oil is synthetic, where 5w20 can be either conventional or synthetic.
Perhaps Toyota calls for 0w20 because they feel it needs a synthetic oil? Fed regs are demanding improved fuel economy. The viscosity of oil doubles for every 10deg temp drop. If u choose. Almost all cold oil is bypassed by oil pump via pressure relief valve. U need it really when motor is outside, in f temps. If you are bored this afternoon review previous discussions here on this subject FlaGeezer.
We have worn the subject out. According to this chart would I be better off using the single weight 30 in both cars?
Note that the double asterisks says that for the 5W oil " Do not use for continuous high speed driving". Use what the manufacturer tells you to use.
The engine is engineered for not or or etc. I would not use single weight oil in any modern engine. Use the car makers recommended oil for your climate. For some reason that chart that I tried to link to my previous post did not appear but the charts that I have seen show that the single weight 30 oil is good from 30F to F ambient. Whereas the 5w recommended by Honda I realize that they have to make that recommendation for the whole world, so it is a CyA posture goes from F to 68F.
Clearly in my case, it would make sense to use the 30w. But hey, judging from the previous comments from veteran posters, this is beating a dead horse! There is a lot going on backstage with 0W oil. Toyota specifies 0w20 for maximum fuel economy and 10, mile or 1 year oil changes. Whether you decide to or not, it can be used for extended intervals of up to 10k miles.
Even of you decide not to extend it that far, you can feel more comfortable knowing that if you change it normally at 5 k miles and take trip, delaying it to say 7. Right now because I took an un scheduled trip, I am almost 2k over on the vehicle that does not use synthetic.
I am much more concerned then if it happens on the one with synthetic. When I lived in colder climates…I used the recommended oil without fail. Get to know how much oil your engine uses, and make sure it never gets below the FILL line. Stick with the 0W20! It has much better film strength and resistance to thinning out in hot nweather due to a higher viscosity index, which is the resistance to thinning out and to thickening in cold weather. In hot countries without fuel economy standards they will put 5W30 in your car to make sure the oil film on the bearings will be sufficient under stress.
I had a conversation with the service manager not the service writer at the Toyota dealership where I bought my Toyota Sienna. The manager told me that Toyota had come out with a new recommendation that the oil change mileage had been extended to 10, miles. All they did was reset the maintenance reminder light for no charge. I was skeptical, but the service manager and I sat down and talked about this over a cup of coffee.
He is an older person not as old as I am and said that oils had improved over the years that I had owned a car and that the synthetic 0W takes care of the engine no matter what climate I operate the car. However, my maintenance light still comes on at miles and has to be reset.
