Can you mix 5W-30 and 0W-30? (2023)

Can I Add 5w-30 To 0w-30? Is it possible? Yes. Viscocity oils flow slower than viscosity oils, so 5W30 will flow faster than 10W30 and 0W30 will flow faster than 5W30.

Is 5W-30 the same as 0W-30?

The 0W-30 engine oil is a lower viscosity than a 5W-30 meaning it is thinner. As the 0W-30 is a lower viscosity, its resistance to flow is lower. The lower viscosity grade flows through the engine faster and helps the parts perform their roles more efficiently as they reduce friction.

Can I mix 0W and 5W oil?

As mentioned, you can mix the (w) portion. The 0w or 5w is the winter rating of the oil which shows how well it will hold its viscosity in colder climates. The other number is the weight of the oil and can’t be mixed.

What oil Can you mix with 5W-30?

These two motor oils are very similar in viscosity; hence, they might mix perfectly in your engine. Therefore, you can mix 5W30 with 10W30 with no ill effects whatsoever.
