Do you really need an oil filter after say the engine is broken in. I have read that this is primarally why there installed to catch break in metals that would quickly kill the engine. After break in wear metals are much lower and less of a threat.

My truck runs better after I change the filter so it must do something.

VW originally thought that in their air cooled jobs. History doesn't seem to support that posture. All the rebuild California type sand and street buggies pride themselves in oil filtration as well as cooling, so I think the filter has a valid place.

On the original air cooled VWs the #3 exhaust valve went at about 80,000 miles so lack of filtration wasn't the limitation on engine life
#3 exhaust valve was a problem because the in the cooling shroud oil cooler was over #3 cylinder and it restricted air flow and preheated the air for #3.

I have cut open a few filters to see their construction and how well they held up and I have seen small metal bits inside the filters... I have also seen iron grit sticking to the side of my oil filter inside because I use a Filter-Mag magnet. So in my opinion it catches a lot of otherwise harmful metal debris. (Most can't be seen by the naked eye though)
During a cold startup your filter goes into bypass. How much of the trapped stuff would you say get flushed back into the general oil sump? Is the flow velocity through the filter high enough to imbed these particles into the media so they won't easily come back out?

My father put over 150K on a 70 Beetle and then 145K on a 74 Beetle running pennzoil 10w-40 and never had any engine problems. All internal engine parts were the original parts when he wrecked each car.

I don't think it's very much, if any. When the bypass is open, the oil is still pushing against the filter element and flowing through it at a reduced rate. That should be enough to hold the debris in the filter media.

That was bout the time VW put a bump out in the doghouse and moved the oil cooler so it didn't restrict airflow to #3. I don't know the exact year but my 1971 had the moved oil cooler.
Engines are like lightbulbs, some last many hours longer than average. 80k something miles was a real common mileage for early air cooled VWs (1950s and early 1960s) that were driven hard to need serious engine work. With a top speed of about 70 mph, most early VWS were driven hard.
I'm not knocking them, you could take one of them, stick you foot on the floor in 100F weather and get 80k miles out of it. Most other low priced imports of the 1950s wouldn't take 10,000 miles of that type of driving. A semi-skilled amateur could remove and replace the engine in under 30 minutes and full rebuild kits were inexpensive. I timed an independent VW mechanic that was showing off and he r&r'd a VW engine in 20 minutes.

Do we need synthetic oil, or 4 wheel disk brakes?
I welcome the added protection with open arms!!!

If you look back BobIsTheOilGuy did run and test a car on different filter and NO filter. By UOA was not too important.
The VW 1600 (1585) can easily go 100,000 miles with a doghouse oil cooler no oil filter. Older style stuff if kept on top of (adjust valves and torque heads) will too.

Not necessarily so. I believe from Gary's tests on here, it was rare that the filter ever went into bypass. I would like to think a filter that flows well like the EAO will never see bypass.

I bought a '76 Beetle brand new and drove it 160k miles. It too went to the wrecker running like a top.....
The floor and body had rotted out and I was tired of watching the road go by, under my feet !!
No oil filter on that puppy...

You see!! no oil filter, the floor rots away in a blink of an eye!!
Thats proof for me!!
Why would you not want a oil filter. All it dose is good
Cleans my oil and keeps metal particals away from my engines insides including my cams?? Count me in!!
