- 9-3 2003 Convertible
Oil thread
Ok - I know im being paranoid - but just want to confirm. I recently purchased a 2003 9-3 Convertible. The manual calls for 5-30 synthetic. I used Pennzoil Platnium 5w-30 about 2 weeks ago (100 miles since changed). Anyway, Im reading now about 0w-40. Do you think I should replace the oil with Mobil 1 0W-40? Also, I purchased a OEM GM Filter - can I use that filter with Mobil1 or do you recommend a different type. Any help would be appreciated. Oh and the VIN has a Y in it - if that helps.
Thank you.Last edited by nordwulf; 12 April 2011 at 12:44. Reason: Moved post to new thread

I'm no oil expert, but as long as it's a decent synthetic, you'll be fine. I wouldn't go wasting all that oil. The PP is a very good oil. I only use Mobile 1 because the local Autozone always has good deals on it when I get it, but the first couple times I used the Castrol Syntec... don't notice a difference.

I don't think you'll want to use a 30 weight oil in that era of 9-3. Doesn't hold good oil pressure, and is one of the reasons for the sludge issues with those cars. I used Mobil1 10W-40 for a while, but switched to Rotella 5W-40 full synth which I think is better (some people have done oil analysis on M1 oil and found a couple issues with it...I had no problems, but changed anyways).
And I think the GM filter is fine, I ordered a bunch of them through eeuroparts some time ago. Make sure you're doing 4k oil change intervals.
