Personally I think that I would stick with the 3.8 filter.....I don't really see the benefiet of running the 5.7lt V8 and 4.3lt V6 filters on these. I'm not one to mess with real serious stuff like that. I mean just because it fit'* doesn't mean it works the same or better. For all we know it could work worse then the OEM and be causing damage?

I wouldn't bother. From what I've heard, all oil filters are pretty much pointless after 1000 miles any ways.

It makes plenty of sense. If you run synthetic you want a good filter that lasts as long as your oil change interval. I'm doing around 5k now a change. The more filtering area the better I think.

Les miles per square inch of filter can only help.

Assuming that it is actually beneificial....

Makes perfect sense to me, something i wish i had known about when i had mine, by 3K the oil was pretty dark, by getting a deeper oil filter, you can extend your change interval if you go by color and smell of the oil. Obviously if you do alot of in city driving i wouldnt recommend going over 5K regardless, moisture still gets trapped in the oil, especially start and stop situations.

Dude. No. Quit listening to those people.

I think that if this was the case, a lot more people would be running the larger filters. Seeing how our cars take the same amount of oil as a newer 350 (5.7) or 262 (4.3) I don't think that you'd be gaining anything. Plus if it was meant to be, GM would have been running these filters from the get go.

If GM was smart, they wouldn't put the PCV valve under a bunch of crap, and 1/8" away from the intake plenum. If GM was smart, they would have a two bolt thermostat housing. GM isn't smart.. they screwed up a lot of crap on my car.. I rather human input.. computers and other dumb people that get paid minimum wage, don't make the best decisions.

also, I've been getting mixed answers now.. which car should I get one from?

What is the difference in price? If it is not that great, I'd buy the larger one (personal preference). But lets be honest, our cars are not going to suffer for using OEM size and brand (AC Delco). The bigger question is not the size of the filter, but the quality. Look for a quality filter, tested by an independant laboratory. Then select the size that you wish to use (3.8 specific or 5.7 specific). I like the longer ones due to the ease of removal/installation. The argument of larger capacity giving more life and more filter surface area has merrit...but the question is, does it make a substantial difference in the longevity of the car, and is it worth the extra cost (if any)? That is a decision that only you, the owner, can determine. What is for sure is that a larger filter will in no way hurt your car.

You be the judge.
