oil change!

I have 3 different syntetic motor oils can i mix match them?

 

As wolfpack said, make sure they are all the same viscosity first. I can't see how it would cause any harm to the motor. But with that being said, I wouldn't mix oils in my truck. It's cheap enough to just buy a few extra quarts.

 

I always buy what is on sale in pep boys always 5w30 syntetic so i have castrol mobil1 and something else but all the same only difference is brand!

 

Cheap? I remember having fits when the price of a quart of oil shot up to $0.55/quart. I choke every time I buy oil now, but it's cheaper than engine repair.

 

Just don't do it too often. at least in my opinion

 

Different brands of oil will have different additives, but as long as the oil is the same viscosity and same API service classification it will be okay. I've mixed Mobile 1 and Royal Purple.

 

I know haha...that's why I said 'cheap enough'.
