? on oil fitters....

Tim H · 10-06-2012, 03:08 PM

I used to manage an AC Delco parts store for almost 10 years.(from 1994 - 2004). I also worked for jobber stores who sold Fram and Wix. I have personally had a Fram filter fail on my own Chevy V8 engine in my race car. I have never had any issues with an AC Delco oil filter and can't recall any customer issues either. Most recently I sold Wix mainly while I worked for Napa. (the last 7 years). The quality of Fram has definetely deteriorated once they started being distributed by big box stores. AC Delco used to be a decent filter and whether you bought it at a dealership or at Walmart is was the same filter. Wix seems to be a good product especially the Gold series. The Wix Racing series is a stout piece but it is not available for a whole lot of engines. Presently I use Wix gold series on my bracket race 600 hp Monza. I would not recommenend a Fram to anyone,at least not the entry level orange filter. A friend uses and loves the K&N filters on his low 10 second SB Chevy Camaro. On my daily driver Suburban I use AC Delco because I bought cases of them years ago, the PF1218 and have been satisfied. Ac Delco used to be mfd by Champion Labatories (Luberfiner) at least in Canada.(our filters were white in colour while the USA versions were blue).

Thanks guys for the comments. One reason I posted was I have noticed on my wife's TrailBlazer, straight line six, is sometimes you hear a nock or bump when you start the car up, not it the morning, but other times. As I understand there is a valve, in the filter, that keeps oil from draining out of the block so to have oil in the block for start ups. This is what I understand. The engine never did this until about 3 or 4 changes ago. I change the oil and filter every 3000 miles. Please correct me if wrong.....and again thanks..frankchastain

Please keep in mind this is a personal use car.....

You are referring to the bypass valve.
Each car manufacturer has a specific setting for the bypass valve based on the engine design.
The worst offender of any oil filter is Fram; I stay away from them.
The best built and design oil filters are Wix (NAPA brand), Baldwin, Hastings and Amsoil.

Anti drain back valve,allegedly developed to correct the infamous cold piston slap in millions of GM 3.1 litres back in the early 1990's.

All I will use is Wix.
