Can you put 10w30 in a 5w20 engine?

Originally Answered: Can I put 10w30 instead of 5w20? You can, but you will get worse mileage, and in most cases shorten the life of your engine, as it will take longer to pump up pressure for your bearings and lifters, and won’t spray your lower cylinders for an extra second or so on each cold start.

Is 10w30 OK for 5w20?

10W30 is thicker and protect older engine with its sealing capability. 5W20 is thinner multi-grade oil that is pertinent for quick starts in the lowest temperatures. In order to protect your car from internal damages, it is beneficial to use only specified engine oil by the manufacturers.

Can I put 10w30 in 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.

What’s the difference between 10w30 and 5w20?

Main Differences Between 5w20 and 10w30

5w20 is thinner at lower temperatures, whereas 10w30 is thicker at lower temperatures. 5w20 is better for cold-weather starting, whereas 10w30 is better for sealing action. Light duty petrol and diesel engines use 5w20, whereas large weight carrying engines need 10w30.

What is 10W 20 oil used for?

MOTOR OIL EXTRA SAE 10W/20 is suitable for vehicles, motorbikes and stationary systems that are operated with monograde motor oils. EXTRA SAE 10W/20 monograde oils can also be used in specific gears and hydraulic systems for which monograde motor oils are required.

What happens if I put 5W-30 instead of 5W-20?

Using 5W-30 instead of 5W-20, you risk damaging your car’s engine because the internal engine components work with 5W-20 motor oil. … It means that both motor oils have the same viscosity under cold temperature. However, 5W-30 has a slightly higher viscosity at 212 degrees Fahrenheit than 5W-20.

Can you use 10w30 oil in a generator?

Ultimately though, 5W30 or 10W30 are fine in most cases, for most vehicles and generators. Likewise, you’ll often find that using either mineral or synthetic oil is fine. You can even mix the two!

Is 10w30 good for high mileage?

Mobil Clean High Mileage 10W-30 is designed for vehicles with more than 75,000 miles. Its advanced formulation helps protect seals and prolong engine life. … These oils protect against sludge and engine rust and corrosion under high and low-temperature operating conditions.

Can you put 10W oil in a 5W car?

Both are the same viscosity at operating temperatures. But which was recommended by the manufacturer of your car? If they originally recommended 10W-30, they you can use 5W-30 or a mixture. If they originally recommended 5W-30, your mixture will not pump as well at very cold temperatures.

Is 5W 20 the same as 5W 30?

The 30 refers to the viscosity at higher temperatures. … So, due to viscosity, 5w20 is a thinner oil during operating temperatures, whereas 5w30 is thicker during operating temperatures.

What oil is thicker than 5W 20?

A.

When it comes to their higher operating temperature performance, 5W30 motor oil performs slightly better than 5W-20 and is a thicker oil than its counterpart. 5W30 motor oil would be more robust and not break down very easily at a higher temperature.

Can I use 10w30 instead of 10w20?

The w as in 5w or 10w means winter. Running 10w30 oil in a hot climate is certainly ok and probably preferable as it will hold up better.

Which oil is better 10w30 or 20w40?

20w40 is thicker at high temperatures (normal operating condition of engine) compared to 10w30. For proper lubrication at operating temperatures high viscosity is desirable. So 20w40 will be good compared to 10w30 at normal operating conditions.

What does the 20 mean in 5w20?

5: this is the oil’s viscosity rating at low or winter temperatures. w: this stands for “winter,” and is part of the “5” rating. 20: this is the oil’s viscosity rating at high temperatures.
