Quick Answer: What Is The Best Motor Oil For Hot Weather?

Which oil is thicker 5w30 or 10w30?

10w30 is thicker then 5w30 because it has a higher viscosity in low temperatures.

The engine oil will flow slower than 5w30 during the cold season.

Thicker or higher viscosity metal oil has a better seal compared to low viscosity oil..

Can I use 10w 40 instead of 5w30?

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 mix synthetic and regular oil?

Yes. There is no danger mixing synthetic and conventional motor oil. However, conventional oil will detract from the superior performance of synthetic oil and reduce its benefits.

Can I use 20w50 instead of 5w30?

20w50 is actually thicker than 5w30. This will result in less fuel efficiency, less horsepower, and more engine damage because it will have to work harder to rotate. Trust the engineers that made your vehicle.

Is 5w30 or 10w30 better for summer?

5w30 is a great multigrade oil for use in low starting temperatures as well as high summer temperatures. It is also more fuel efficient since it creates less drag on the bearings and moving engine parts. 10w30 is thicker and may provide better sealing capability for older engines.

Is SAE 30 the same as 10w30?

SAE 10W30 is an oil that has SAE 10W viscosity(thickness) at low temperatures, and SAE 30 viscosity at high temperatures. The W stands for ‘Winter’. … At operating temperature, there’ll likely be little difference between SAE 30 and SAE 10W30. In theory, they’re the same at high temperature, which is IIRC set at 100C.

Can I switch from 5w30 to 10w30?

The oils only differ in cold weather viscosity. If you never see temperatures below zero F then either 5W30 or 10W30 is fine. … You don’t really need to change to the 10W30. The 5W and 10W are the numbers that tell you the low temperature behavior of the oil and the second number tells you the high temperature behavior.

Does thicker oil run hotter?

Not only that, but the engine will waste energy pumping the thicker motor oil, reducing fuel economy. Since thicker oils don’t transfer heat as well as thinner oils, operating temperatures will increase, too, possibly leading to accelerated chemical break down and harmful sludge and deposits.

Is 10w40 good for summer?

Using 10w40 oil in the summer will help the oil stick to internal components in high temperatures, avoiding the wear and tear from metal-to-metal contact between moving parts.

Do cars burn more oil in hot weather?

The hotter your engine runs the thinner your oil will be. Once again it will be simpler for a thin oil to reach the combustion chamber and get mixed and burned with the fuel. Too-low viscosity motor oil.

Which oil viscosity is better for warm climates?

Use a Multi Viscosity Oil A multi viscosity oil flows at one rate when cold, and another when it has warmed up to operating temperature. For example, a 10w30 oil flows like a thinner 10-weight lubrication in winter and a thicker 30-weight oil once it’s warm.

Can I use 5w30 in hot weather?

Unlike oils with a higher hot temperature rating such as 10 or 15, 5w30 oil can flow freely enough when the engine is started at low temperatures to coat and protect the engine’s internal components. It’s also a good choice for long trips requiring greater fuel consumption and more exposure to heat.

Is mixing 5w30 with 10w30 bad?

Mixing different oils will not improve the performance or efficiency of the engine in any way. … 5w30 and 10w30 are both 30 weight oils and the exact same thickness in your engine when it is at operating temperature. The 5w30 is better because it thickens less when cool or cold. Thinner oil gets to the top end faster.

Can I use SAE 30 instead of 5w30?

No. SAE 30 is a single viscosity motor oil. Only multi viscosity motor oils only should be used in any car. … 5W30 is motor oil that is thinner when cold than 30 weight motor oil and thicker than 5 weight motor oil when hot.

What is the best weight oil to use in 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.

What happens if I put 10w30 instead of 5w30?

Your oil is a little thicker when cold. No damage will happen. … The 5W and 10W defines how the oil will flow at 0 degrees. At operating temperature, there will be a completely insignificant difference between the two.

Does thicker oil protect?

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.
