Quick Answer: Is 5W-30 or 10w40 better for summer?

While some car manufacturers still recommend 10W-30 (or even 10W-40) as an appropriate engine oil option for summer use, there is no need to switch to 10W-30 motor oil in the summer if 5W-30 is an acceptable grade for your engine.

Is 10w40 good for summer?

They are both available in pure conventional form or as high-quality synthetic grades. Either 10W30 or 10W40 for summer use is fine
however, 10W-40 motor oil will better protect your engine.

Is it OK to use 10w40 instead of 5W-30?

Your vehicle does not use 5W-30 oil. The recommended oil viscosity for your vehicle, according to Kia documentation, is 10W-40. If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.

Can I use 5W-30 in the summer?

The 5w30 oil is a great multigrade oil that can be used in low starting temperatures and high summer temperatures. In addition, it is more fuel efficient since it reduces the drag on the bearings and engine parts, which reduces fuel consumption.

Is 10w40 good for high mileage?

Is 10w40 Good For High Mileage? The 10w30 and 10w40 oil options are both acceptable for your car, but if you have a high mileage car, you should use the 10w40 oil. Older engines are able to handle higher temperatures and wear and tear more efficiently with thicker oil.

Which oil is better in the summer?

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 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. While some car manufacturers still advocate the use of 10W-30 (or even 10W-40) as an appropriate engine oil option for summer use, it is completely unnecessary.

Which engine oil is best for hot weather?

The best motor oil for hot weather is Valvoline Advanced Full Synthetic 10W-30 Motor Oil. Diesel Motor Oil from Shell Rotella T5 Synthetic Blend 10W-30. This is a full synthetic 10W-40 motor oil from Castrol Edge. The Valvoline High Mileage Synthetic Blend 10W-40 Motor Oil is a high mileage oil.

Which oil viscosity is better for warm climates?

A climate that experiences warmer temperatures all year long may necessitate a heavier engine oil such as an SAE XW-30 or XW-40 grade – one able to resist the breakdown that comes with higher operating temperatures by ensuring proper and adequate film thickness and the protection of critical engine components.

Can I mix 10w40 and 5w30?

Is It Ok To Mix 10w40 With 5w30? The brand should be the same as the product. It is not compatible with the additives to mix brands.

Is 5w30 or 10W30 better for summer?

Generally, you’ll get the best protection in the summer when you use a thicker grade of oil, such as a 10W30 instead of a 5W30.

Is 10W-40 oil good?

10W-40 motor oil’s greater tolerance for hotter temperatures means that it’s better at resisting thermal breakdown and reducing deposit formation. So, if you drive in a warm climate — especially more than 32°C (90°F) — or have an engine that runs hotter than others, 10W-40 oil viscosity is a good option.

Is 5W40 better than 10W40?

5W40 vs 10W40 – Differences

The 5W40 is thinner than the 10W40 at lower temperatures. But when the temperature is higher, both motor oils similarly perform their intended functions (using the same viscosity). If your motorcycle requires a 10W40 engine oil, there is no need to go for 5W40 oil.

What is the difference between 10W 30 and 5W-30?

The main difference between 5w30 and 10w30 is that 5w30 is less viscous and more efficient than 10w30 because the fuel is thinner and can reach the difficult part of the engine. 5w30 is a viscosity engine oil that is used for engine lubrication.

Whats the difference between 10W and 5W?

A 10W or 5W is the index for how easily the oil flows in winter (hence the W). A 10W oil thickens more than a 5W. The other number indicates the oil’s resistance to thinning at high temperatures.

What is 10W-40 oil used for?

This oil weight is commonly used in diesel engines or in a smaller motorcycle engine too. The 10W-40 oil viscosity also often serves as an alternative for older engines with burning or oil leaking issues. Why is that? The 10W-40 engine oil has a thicker viscosity than, say, 10W-30 oil when the car engine is hot.

What is 10W-40 oil for?

Higher viscosity oil such as a 10W-40 can be useful for older engines burning or leaking oil. We offer Mobil™ 10W-40 high viscosity motor oils for use in vehicles with more than 75,000 miles, and a synthetic blend oil when cost is a consideration.

Is 10w40 better for older cars?

Is 10w40 Better For Older Cars? When you put more pressure on your vehicle’s engine at high temperatures, 10w40 will reduce wear and tear on the engine and make it more durable. 10w40 is also an excellent choice for older vehicles.

Should I use a thicker oil for hot weather?

Is Thicker Oil Better For Hot Weather? In the winter, thick oil would clog pumps and prevent them from lubricating properly. Heat can thin motor oils, so they should be thicker and more resistant to thinning. It is necessary to use a motor oil that maintains the right thickness during the summer.

Is 5W-30 good for winter?

An example is 5W30—the “W” stands for winter and the oil’s cold weather rating. The lower the W number, the better the oil will perform in colder temperatures. Typically, a 5W oil is recommended for winter use, but synthetic oils can be formulated to flow even more easily when cold.

Is 5w 40 oil good for hot weather?

5W40 is better for starting your engine at low temperatures as it flows more easily at these temperatures. When the engine is running and hot, 5W40 and 10W40 have high viscosities and are equally effective in protecting against engine wear.
