Yeah, ummm....next time go amsoil s2k 0W-30 for 15-25k with an amsoil Ea filter or M1. Valvoline is not the "best" by any means. :P

And you can go alot cheaper on a filter. Purolator PureONE or Delco filters are just fine. As far as larger capacity, anytime you need to look up a code in store, look for anything with a LT1 350 in it. Like a 94-96 Impy SS. Those use the bigger filters that are compatible with the 3800. Thats off memory, someone catch me if I was terribly wrong on that.

You won't get the extended performance off the M 1 filter though....

Also with the Seriess 2000 0w-30 oil it'* 17,500 miles/1 year severe service and 35,000 miles/ 1 yr for normal service.

Just needed to correct that error

and the bigger filter is NOT off a LT1....its off a 4.3L S10 or blazer....AC delco PF52

LT1'* used the same filter pat

every time i look up a LT1 for a 96 caprice its a PF52 or what ever model for other brands.

well good to know.....

I've run Fram for 20 years... never a problem.

Karl....the fram is BAD news in a 3800....its been proven. People that run Fram have seen low oil pressure right after a oil change....they put a quality filter on the car and the OP comes right back up to normal

Please dont run one on your SSEI

How big a drop? I'm planning on going with Mobile 1 either the next change or the following one. I'll keep it in mind.

Does advance even sell "amsoil"? And I dont care how good the oil is, my car will never go more than 3000 miles without a change. I just know that the valvoline oil I use costs alot of money so it has to convey some amount of quality to the product. I'm not saying the most expensive is always best but it still matters to an extent. And I just know mobil 1 filters are good so I stick with what i know.

There aren't too many retail stores that sell Amsoil to my knowledge.

As for the oil quality...Valvoline'* alright, but there'* better. You can still change your oil every 3000 miles if you're stuck in that rhetoric...It'* your money...

But Going this route and changine at a minimum of 15k will save you $$ in the end...That'* what I'm out to save....and run is the high quality stuff, and save money on the long term.

Sure Valvoline'* not on this chart, but here'* a comparison of some other oils:
