Hi Madooch - there have been many, many posts about oil change advice here. Use the Search feature above to do some more looking. Here are two of my previous posts on the subject:madooch said:ok guys i will be doing my first oil change on a 02sts and wondering what would be the best oil to use and what grade oil i should use thanks in advance.
I'm kind of curious about that as well - I've used Fram filters on domestic cars for years without a problem. However, yesterday (in life as in comedy timing is everything!) one of the other engineers I work with had an interesting tale of woe to relay.jamesmdx1 said:Why stay away from FRAM oil filters?
Found this some time back. Can't vouch for the accuracy but it is interesting reading.jamesmdx1 said:Why stay away from FRAM oil filters?
I have personally seen and heard of too many problems with Fram filters to ever recommend them for anything other than expensive paper weights. Yes, it's my opinion, and I'm open to discussion. I have seen problems with noisy valve trains at startup on a 99 Camry and an 03 Expedition that were solved by switching filters and a seized Escort engine after the Fram filter casing burst apart at the seam and the oil light didn't work. Never heard of any problems with any other filter brands. So I will not use Frams and do not recommend them, plus I have read too many bad reviews such as the one listed above. Here are a couple others:DFBonnett said:Found this some time back. Can't vouch for the accuracy but it is interesting reading.
Jamler - Don't you think the engineers took these factors into account when they made their recommendations? The only Northstars that require synthetic oil are the ones with VVT. The actuation pump for the VVT system is what requires the synthetic oil properties, not the temperature of the engine or anything else. It's just the VVT pump. When GM tested the Northstars, they tested them in actic cold temperatures and Death Valley hot temperatures, in labs and on the tracks, and guess what? They did all the testing with conventional, non-synthetic motor oil. They do not require nor do they recommend that you use synthetic motor oil for any non-VVT Northstar engine.Jamler said:You guys are scaring me with all this "Extended Oil Life" Stuff.....
First of all... Everybody knows the NorthStar is a hot running engine... And kinda likes it that way!!!!! That said, I've experienced some engine oil burn off. If your burning off some oil, well then its in your best interest to check/monitor regularly and change every 3-5K! That's what I plan to do.
RE: Oil to use... I'm using Mobil-1 5w-30... What Caddy Recommends for STS.
Mobile-1 actually makes a point of indicating this on their containers! Why wouldn't they right? But I'd rather be safe than sorry!!!
