What engine oil is best for tropical climate?

In tropical weather, most OEMs still recommend multi-grade products, such as SAE 15W-40, because the lubricant flows faster through the engine than a pure SAE 40 even at higher ambient temperatures. Another important consideration when choosing an engine oil is the quality certification or performance level.

What is the best engine oil for hot countries?

The ideal motor oil for your car is one that can withstand the hottest temperatures in your region while still being able to flow when the weather is at its coldest. SAE 5W30 oil is suited to a broad range of temperatures, making it one of the most commonly used oils on the market.

Which engine oil is best for summer season?

As a general rule, you’ll get the best protection in the summer when you use a slightly thicker grade of oil, such as a 10W30 instead of a 5W30. Engines need a thicker oil in the summer months because of the summer heat and its effects on thinning the oil out.

Is 10w30 good for hot weather?

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. Then, multi-grade oils were formulated.

Is 5w 20 good for hot weather?

RE: 5w-20 in hot weather? 5w-20will not necessarily break down faster, it will justhave a lower viscosity when it’s hot. Synthetic oil will take longer to break down, and you can get it in 5W-20 or 30.

Can I use 10w30 instead of 5w30 in summer?

Although both 5w30 and 10w30 are multi-grade, the latter thins enough when living in an area with extremely low temperatures. This makes it perform much better during the winter season than 10w30. 10w30, on the other hand, will flow effectively in hot summers or higher temperatures.

Is 5W or 10W better for summer?

Answer: There is absolutely no need to switch to 10W-30 motor oil in the summer if 5W-30 is an acceptable grade for your engine. Remember also that a 10W-30 and 5W-30 are essentially the same viscosity at operating temperature, so there is no tangible advantage switching over to 10W-30 for summer driving.
