call me a heretic, but i'm running a fram oil filter in mine (just cuz i needed a filter and that'* what i had lying around), and i have very good oil pressure, like 60-70 when i start and 45-55 after it warms up...that'* with normal pennzoil dino 10W-30

See I'm anal about changing my oil. I run Mobil 1 5w30 and still change it every 3,000 miles even though I know it can go longer.

I've read all the BITOG comments on Frams for years. I think they're an inferior filter (glued cardboard end caps!) in most applications. I'll take a Wix, Purolator, or a WalMart SuperTech over a Fram, personally. Whether or not they are directly responsible for grenading an engine is another story, though.

I drive 50 miles round trip every day to work, mostly at highway speeds. I feel very comfortable using conventional Castrol GTX and a good filter and going 5k miles on an oil change. The used oil analysis I've seen from these confirms that they are easy on oil. I also run the longer filter (like from a 1994-1996 LT1 350 in a Caprice/Roadmaster). I think it would have more filtering media, but I really do it just so I can use all 5 quarts in an oil change.

If you want to help your motor to it'* maximum life, my suggestion is not to start extending the life of your oil. Instead change the oil every 3,000 miles like many here do.

I personally believe in 3,000 miles Mobil 1 and either Mobil 1, K&N or Napa Gold oil filters.

180,000 miles and I put a cam into it last week.

I think that 3k intervals on Mobil1 is a waste of money. Ours will probably both go 250,000 miles without an oil-related failure. By then, the rest of the car will be worn out, and I'll be sick of it anyway.

A GM oil life monitor would probably let me go about 8-10k under my conditions. Now THAT is excessive, especially on conventional oil.

Different strokes...

I dont trust oil life monitor'*


Why?



Because Auto companies only want cars to last 100-150K. they dont build them anymore to last. If they did they would make no money.

So i dont trust something like that. And whats another $100 a year to make your car last another 50-100K miles.

I understand what you're saying, but driving 5k on the oil and filter I use is just fine, and backed up by used oil analysis. In fact, any no-name SM-rated oil and any decent filter will probably allow for more miles than any person wants to drive any one car. I wouldn't, and never have suggested following the OLM, though.

I recommend Mobil 1 and either a Delco, Purolator PureONE or Mobil 1 filter. Fram is crap. I usually believe 3k, but it says right on the M1 bottle that they recommend your manufacturers MAXIMUM recommended interval which i believe to be 7500 miles on modern 3800 engines. But if you want to pay more overall for more oil changes, more power to yah, it can't hurt.

I will agree with ya 62... it'* a little excessive at every 3K..

When you drive like i do.. it'* sound advice.

I have to agree also. I just got mine done yesterday and before the 3000 mile time
