What kind of oil does a 2003 Toyota Corolla use?

Engine Oil SAE 5W-30 is the best choice for good fuel economy and good starting in cold weather. If SAE 5W-30 is not available, SAE 10W-30 may be used.

What happens if you put 10W-30 instead of 5W-30?

Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine. 5w30 and 10w30 engine oils have close viscosity, and thus there is no harm in mixing them.

Can I use 5W 40 instead of 5W-30?

In practice, this means that each oil is just as viscous at lower temperatures and will remain viscous at -30°C, however 5w40 oil outperforms 5w30 oils at higher temperatures, being effective up to ambient temperatures of 50°C, as opposed to 30°C.

Is 10W-40 the same as 5W-30?

A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.

What kind of oil goes in a Toyota Corolla?

I use this Pennzoil Engine Oil High Mileage Full Synthetic 5W-30 for the excellent performance and viscosity in my Corolla with over 325,000 miles.

Does 10W30 hurt 5w20 engine?

Modern cars are designed to use lower viscosity oil ranges, so they can properly lubricate ( see attachment) Going from 5w-20 to 10w-30 should cause no harm for one oil change. But if you engine as designed for 5W-20, give it 5W-20.

What is the best oil for a car with high mileage?

#1 – Mobile 1 High Mileage Synthetic Oil Mobile 1 High Mileage is a synthetic motor oil which is formulated to keep high mileage engines alive for as long as possible. The oil is more resistant to higher temperatures and has a less chance of causing leakage.

What happens if I use 10w40 instead of 5W-30?

If you use 10-w-40 instead of 5-w-30 specified by the manufacturer then the viscosity of 10-w-40 used by you will be higher and oil thicker than what is specified during winters. Similarly the oil viscosity will be higher and oil thicker than specified during summers.

What is the difference between 5W-30 and 5W 40?

5w30 is engine oil that has lower viscosity 5 and higher viscosity 30. 5w40 is engine oil that indicates the weight and viscosity of the engine. 5w30 has lower viscosity hence it is suitable to use in hot or lower temperatures. 5w40 has higher viscosity hence it is not suitable at all temperatures.
