Nuttin' but Mobil 1 Synthetic for her.

Congrats on the purchase! hope to get my Cruse here this summer, and i honestly think i'm going to jump ship on the Taupe Gray and get the Red w/RS. because that is a really nice looking car!

just make sure that the M1 you get is DEXOS1 approved... it's important.

As far as Mobil 1 is concerned, I'm not too worried about it. I've been using it for 22 years and have never had a problem with it.

i think you'd have a problem with it if it voids your warranty...

If it's not DEXOS1 oil, it's got no business being in your engine. Doing otherwise will void your power train warranty.

fortunately, Mobil1 5w30 has been approved for the Dexos1 specification... not that I'm surprised (since Mobil has been working with GM for the last decade or so).
