you guys want to read about fram filter failures? for starters: google dsm fram oil filter haha that’ll keep you occupied. my 94 camaro took an oil bath on the south side of indy one night because of this phenomena. fun fact: he put a new fram filter on, same night, it literally blew apart 2 hours later. this was circa 2001...that was enough for me to never use a fram filter. anecdotal, one presumes. several hundred dsm guys disagree.

They cut open a filter and looked inside!

Thanks for the heads up!

I just realized that I have a car that I have never changed an oil filter on. It is my wife’s car so I don’t pay as much attention to it as the others. Now what???

It is an air cooled VW Beetle and I believe none came from the factory with an oil filter, just a screen to catch big pieces. (some late Mexican Beetles may have had filters) Those air cooled engines were used in the beetle and bus. Recommended oil change interval was typically 3000 miles. There were over 21 million air cooled Beetles alone produced and reliably driven all over the world.As an FYI, I know a guy who drives one of his three air cooled bus around the US each year to help other air cooled owners maintain theirs. Those buses see everything from sustained interstate driving to big city traffic. He has over 400,000 miles between the three. Routine maintenance with conventional oil but no oil filter!

And yes, I had one. Two in fact. Centrifugal distributor, tuned exhaust, Holley two barrel. Real screamer.
Relatively speaking...

It was (is) all about keeping the valves adjusted, esp. cylinder 3. 3 always ran hot because the air it received went through the oil cooler first so it was preheated. That exhaust valve needed to sit in the seat as long as possible to make sure it cooled.
Guess we're getting a little off-topic now....

In fact I have not changed an oil filter on the VW because it doesn’t have one It is an air cooled VW Beetle and I believe none came from the factory with an oil filter, just a screen to catch big pieces.

Talking about old air cooled VW's seems less controversial than oil filters so one more. Regarding a 70's and older aircooled Beetle with factory installed oil filter – I doubt it but anything is possible. I believe the later Type 4 did have them. More likely on a Beetle it was a dealer installed item before it was sold, probably to jack up the profit margin or make potential customers feel better. I have seen that VW sold filter kits as an accessory.
Valve adjustments – absolutely. The recommendation is every 3000 miles. I expect most people ignored that. Not keeping proper cold valve clearance probably damaged more VW engines than anything else.
My last post on this thread. Like Dave said, time to go do more fun stuff.

And BTW - all oil / filter threads end up going way off topic. This is nothing new.

Mine too!
Unfortunately, my last post in threads tends to be like my last cast while fishing.

Testing, conducted at the Milwaukee School of Engineering; Fluid Power Institute using SAE Test Method J806 for filtration efficiency, indicates the following at the lower efficiency end of the graph.
Fram PH8A oil filter is 10% efficient at trapping 12 micron particles.
AC PF-2 oil filter is 10% efficient at trapping 4.5 micron particles.
Purolator PER-1 oil filter is 10% efficient at trapping 14 micron particles.
Ford FL-1 oil filter is 10% efficient at trapping 12 micron particles.
At the upper efficiency range of the graph:
Fram PH8A is 78% efficient at removing 20 micron particles.
AC PF-2 is 67% efficient at trapping 20 micron particles.
Purolator PER-1 is 42% efficient at trapping 20 micron particles.
Ford Fl-1 is 33% efficient at trapping 20 micron particles.

Standard oil related thread - some spirited debating, but it's all good.
It seems like, for those that might be interested in what is popular, that the winner is Napa gold/wix - certainly you can't go wrong with that choice.
