5W-30 oil can operate in temperatures as high as 95°F, after which you should switch to a better high temperature oil viscosity grade. That’s because 5W-30 motor oil is unsuitable for high temperature use. In extreme temperatures, car engines require thicker oil with proper bearing support and cushioning for your engine’s metal surfaces.

What is 5w40 motor oil?

The 5w40 motor oil is a thin oil at seventy degrees Fahrenheit, and it will be forty weight if it reaches the average operating temperature. This usually works in the opposite of what the public thinks. For example, most people think that the motor oil will get thinner if it gets hot. Well, it usually does, but there is the issue of polymers.

Which oil is thicker 5W-30 or 15W40?

Not answering technically here but 15W 40 is thicker compare to 5W 30 but their application is more in Diesel engines compare to petrol engines.

20W-50 motor oil is for vehicles with gasoline engines. 15W-40 oil is for diesel applications. The difference between the two grades are just the specifications and for all practical purposes, in older vehicles without variable valve timing, the two grades of oil are interchangeable.

What is the difference between 15w40 and 20w50 oil?

Using a 15w40 motor oil can be used in engines that have high mileage. On the other hand, the 20w50 motor oil is used more in racing engines and not on high mileage engines. High mileage engines are running very hot and need heavy load operation. 20w50 motor oil is not for those vehicles that are driven daily. Which Is Better, 15w40 or 20w50 Oil?

Is 20W-50 oil good for cold weather?

20W-50 oil is not the best choice for cold weather conditions. It will produce below-average starts and may lead to slower engine performance in freezing temperatures because of its weight, but there shouldn’t be any problems as long as you are using an appropriate grade (such as 5w30).

Is 20w50 better than 5-30?

20w50 is thicker than 5-30, which will result in less fuel efficiency and horsepower. It also makes the engine work harder to turn over since it has more resistance from outside elements like dirt or water vapor on a road surface that could cause lube failure if not removed before entering an internal part of your car’s motor.

Is SAE 20W-50 too thick?

Right on. If you’re running this vehicle in a low-temp environment, then SAE 20W-50 is too thick to provide proper lubrication. First, as a side note, it is very unusual for a car to use 15W40 oil. This is typically used in diesel truck engines (is this a gasoline fueled vehicle?)

Is it OK to use 5W40 instead of 15W40?

YES. Lowering the first number gives you much faster oil circulation on every startup, and especially in the cold. So you engine will have lower wear on every start-up. And since it flattens the viscosity curve, in hotter areas, like turbos, a 5W-40 will have more viscosity than a 15W-40.

Can I use 5w40 motor oil instead of 15w40?

Yes, you can use 5w40 motor oil instead of 15w40 motor oil. This is because no engine will become damaged if the motor oil is less thick than cold. On the other hand, a 5w40 motor oil will be thicker also when hot.
