Calling Tom-Oil guru...

hi Tom,Kevin here. 2002 rt10. I have found an UNOPENED 4.4L jug of MOBIL 1 10w-30 Synthetic Oil from LAST year. Is it still OK to use on my next oil change. Also it is OK to mix with 2nd NEW jug?

Thanks Tom! What is the BEST oil filter as well?

Thank you.

Yes, as long as the new jug is the same API performance level. Mixing different chemistry at 50-50 should be avoided (adding a quart when low is OK.)

I don't know about filters, sorry.

On one forum an engineer said that after five years do not use the oil.
