At 250,000 miles when I took the engine apart to put it in a 71 VW bus there was still very little wear on those bearings. The cylinders and pistons We’re toast at 130,000 miles and again at 250,000.

It’s true I changed the oil every 1500 miles and it’s also true that the car was 90% of the time used to commute 30 miles to work. But there was no oil filter and only 2 1/2 quarts of oil in the engine. A quart of oil in those days was $.75.! Imagine doing a oil change for a buck 50!

most bikes before the mid 80s only have a screen like the VW's..and were all also air cooled

after my timing chain stuff...im not sold a filter does much too...since the VVT was full of shavings and the filter was nasty but should have still been catching

And he’s got a compelling argument too!

alot of dirt bikes STILL do not use an oil filter...and they are in FILTHY enviroments..of course the change times are very much so more often..they are also beatin on twice as hard...

hell only 2 of my bikes even have filters..the 03 zr7-s and the 83 honda xl600r

with the way the "bypass" plate is designed in all filters..only about 1/2 of the oil is even filtered while the rest just uses the bypass...HEAT has alot to do with that as the hot oil makes the spring compress, to which i say..if you can add a cooler i recomend it as HEAT has alot to do with how your filter works...even better if you can do a sandwich plate and "remote" filter as then the filter isnt on the block sucking head further opening its bypass

in the end a filter is really only designed to clean a little...and is there mostly for the guys who dont take care of their car.....think of it like an idiot light


with my timing chain issues....i flushed more crap out of the engine WITHOUT the oil filter than the filter could catch...so...yeah

Honda Ruckus' still only use a screen. Not sure about Honda's other 50cc mini bikes/scooters though.
