I too must buzz in on the FRAM filter debate. I was a
faithful user until i ran across the discussion on a
motorcyle list i was reading. So i figured id check it out
a bit. Went down to the local Trak Auto and compared the
FRAM to Bosch.. couple things i found out that didnt settle
too well with me..
1. Not sure if it had the drain-back valve, but i know for
sure that it did not have the by-pass valve (which diverts
oil directly to the engine at start up and when oil pressure
is low) the little spring loaded thingy.. im I correct on
2. I usually buy in bulk because have 5 vehicles that
called for the same FRAM part number (2865), or so i
thought. In the FRAM book.. the 2865 is also listed for the
MB 300 engine.. well when i picked up the Bosch.. i just
picked up 5.. until i though .. wait a minute and checked
the book. What gives, a different part number? Does anyone
know the difference in the 2 filters, or is it some kind of
valving thing? I mean does fram just think that if the
threads fit, use it????
3. And lastly, i too had the gasket come off on the engine
only to have oil squirt between the 2 gaskets *laffs*. Can
laff now.. but that really pissed me off!
