Is it OK to mix different weights of motor oil?

It is always advisable to not mix motor oil brands, however, different viscosity grades of the same brand motor oil are compatible. Be aware that mixing viscosity grades will turn out a product that is different in viscosity than either what was originally in the engine or what was added.”

Can you mix 5w30 and 10w30 Reddit?

Christ. Yes. It’s fine.

Can you use 5/30 instead of 10w30?

Yes. 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.

Which oil is better 5w30 or 10w30?

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.

Can you mix 5W 20 and 5w30?

You can mix a 5W20 with a 5W30 oil with minimal amount of issues provided it the same manufacturer and the same API classification. The question is ‘why would you?” If it is because you oil is low and the only thing available is a different grade then it might be fine until you can get it changed.

What happens if you mix different engine oils?

Mixing different types can destabilize your motor oil, reducing its efficiency and affecting your engine’s performance. The smartest choice is to stick with the oil type and oil change intervals recommended by your car’s manufacturer and visit your local car care experts for affordable services.

Is it bad to mix oil viscosity?

There is nothing wrong with mixing oils of two different viscosities, but it is not the optimum condition. You can also mix oils of the same type (engine oils with engine oils, etc.) Remember, when getting an oil change, 15 to 20\% of the old oil remains in the engine and mixes with the new oil.

Is it OK to mix 10W40 with 10W30?

yes you can mix 10W30 with 10W40 as long as the engine will work with both 10W30 and 10W40. In certain high performance engines the 40 could be too thick in certain engines. Most of todays engines use much lighter oils to save on fuel economy and due to engine specifications.

Should I use 5W or 10W?

Absolutely yes for car engines, 5W-30 is usually synthetic and superior to 10W-30. Both have the same viscosity at the operating temperature of an average car engine. 5W has lower viscosity when cool and is considered better for the car engine during engine start.

Is 5W-30 or 10w30 better for winter?

10w30, the thinner 5w30 will circulate quicker, and flow through bearing tolerances better during an engine startup in the winter or colder climates. The “w” behind the five and the 10 indicates that those are the viscosities in colder or winter temperatures.

Is 5w30 or 10w30 better for winter?

Is 5W20 better than 5W30?

Yes, a lower viscosity oil like 5w20 will provide less protection than 5w30 in normal operating conditions. However, a lower viscosity oil is better in areas of the country with lower average temperatures and below freezing conditions.

What oil is thicker 5W30 or 10W30?

5W30 and 10W30 are the oil viscosity. Basically this is the thickness of the oil. The oil has additives that cause it to have a “thinner” viscosity on initial start up but moves to the “thicker” viscosity at operating temperature. This allows for easier starting and getting oil to the lubricated parts quicker.

Is 5W30 oil thicker than 10W30?

A higher viscosity oil, such as 10w30, will flow slower at low temperatures compared to a lower viscosity oil like 5w30. This is important because viscosity changes as temperatures change. Viscosity decreases as the temperature of the oil increases. A higher viscosity or thicker oil will seal better than a low viscosity oil.

Can you use 10W30 in place or 5W20?

When 10w30 is used instead of 5w20 , probably, only a few changes are discoverable especially when the engine is about to wear out and is old. Moreover, one of the benefits of thinner oil would be to ignite quickly. Therefore, fewer efforts are required to pump the fuel, which minimizes the fuel economy.
