Can I Top Off My Oil Using a Different Grade Than the One That is Currently Being Used?

Can I Mix Different Motor Oils?

When it comes to maintaining our high-quality used vehicle from Auction Direct USA, one of the best things we can do is be mindful of the oil. Check it regularly (once a month), have it changed every three months or 3,000 miles, and top it off as needed. But have you ever found yourself checking the oil in your vehicle, realized that it was low, and discovered that the only oil you had on hand was different than the kind you normally use? Is it okay to use? Keep reading to find out!

Typically, it is not a good idea to mix oils, though you may be able to get away with it if the grades are fairly similar (such as using a 30 grade when a 40 grade is recommended). You should never mix conventional oil with synthetic oil.

What Do the Different Oil Grades Mean?

If you have ever been to a store that sells motor oil, you have an overwhelming selection to choose from – and typically only one will work for your vehicle. The grade number listed on the bottle indicates the viscosity of the oil, and the higher the number, the thicker the oil. If you see a “W” on the bottle, that indicates a winter grade of oil to help your vehicle perform when the weather gets frigid.

How Do I Know Which Oil to Use for My Car?

It is always best to follow the recommendation listed in your vehicle’s owner’s manual. However, your preferred mechanic may switch to a different variation one your vehicle hits the 100,000-mile mark. Always ask what kind they used so you can be sure to purchase the same grade for future top-offs.
