I used 5w30 instead of 5w20???

I was so damn excited over the price of oil yesterday at pep boys I bought the wrong grade. I just changed the oil and noticed I used 5w30 when my jeep calls for 5w20 in the 3.7. Should I drain and redo or is it fine??

On the oin cap it says SAE 5w20. I know 5w30 is pretty much within the same temp parameters as 5w20 but Irf scared me and said I should drain it ASAP.

It's probably fine Nate. Me being an anal perfectionist, I would drain it, lol, but I think you'll be alright.

Re: I used 5w30 instead of 5w20???

Nate stop scaring ur self either when they were putting on the oil cap the person who did so was drunk and didn't like white jeeps too so he put the 5w-20 cap on it ...

or it is really 5w-20 which I have not heard of but 5w-30 should be fine

see that's what you get for driving a white jeep other people f with u too lol

Re: I used 5w30 instead of 5w20???

I thought the 3.7 requires 5-30 anyways? And when are you going to take my advice and not listen to Irf?

Leave the oil in. If it was a 5.7 with the MDS, I would agree with Irf. MDS needs the thinner oil for correct operation.
