Is Thicker oil better for hot weather?

Is Thicker oil better for hot weather?

The best motor oil for hot weather is a thicker grade oil to combat the thinning effects of the heat. In the summer, you need a motor oil that will maintain just the right amount of thickness.

When should you use thicker oil?

Within reason, thicker oil maintains a better lubricant film between moving parts. Some have even used thicker oil in a leaky engine to prevent oil from seeping out. But really, thicker oil is not good for your engine. Not when “thicker” means higher viscosity than the manufacturer recommends.

Is 10W 30 or 10W 40 better for summer?

Similarly, SAE 10W-40 motor oil performs well in cold weather conditions. It has the same low-temperature limits as the 10W-30 but is better in higher temperatures. Either 10W30 or 10W40 for summer use is fine; however, 10W-40 motor oil will better protect your engine.

Can I mix 5w30 and 10W30?

Can you mix 5W30 and 10W30? The simple answer is YES; you can mix the two oils; not just because they have the same weight, but because it is safe to mix two different engine oils. However, we do not encourage the mixing of motor oils. Because the act does not guarantee any advantage over using one type of oil.

What do oil numbers mean 10W-40?

The designation “10W-40” indicates a multigrade oil that is toward the low end of the SAE scale in cold weather, but at the upper end in hot conditions. 10W-40 oil is therefore good for a wide range of weather conditions.

Do you really need to use heavier oil in summer?

It used to be that changing oil weight for summer or winter months was part of proper maintenance. Old conventional oil formulations had only one viscosity, and oil would thin out as it was heated. In winter months this caused starting trouble because the oil would turn to molasses and the pumps couldn’t lube the engine properly.

When to use lower viscosity oil or thicker oil?

To recap, a lower oil viscosity number indicates a thinner oil that will flow faster, while higher oil viscosity number indicates a thicker oil which often works better in extreme applications. For engines that do not have a recommended weight – winter and colder temperatures, you should use a lower viscosity oil for cold start up.

What kind of oil should I use in the winter?

A typical winter grade was 10W. A typical summer grade was 30. These oils were straight grade oils. A 10W flows well in cold weather, to protect the engine at start up, but it’s is too thin for use in the summer. A 30 grade oil, thick enough to protect in the heat, was recommended for summer use.

What’s the difference between winter and summer oil grades?

Forty years ago, there were winter grades for cold weather and summer grades for warmer weather. A typical winter grade was 10W. A typical summer grade was 30. These oils were straight grade oils. A 10W flows well in cold weather, to protect the engine at start up, but it’s is too thin for use in the summer.

Which is better thicker oil or thinner oil?

Slightly more viscous oil will help you in protect worn bearings too. When heavier oil will be added to the engine, it will never leak and throw extra smoke out of the engine. Thicker oil can be the best motor oil for hot weather. Thicker oil for worn piston rings might be not the appropriate solution.
