"Every spin-on oil filter I ever installed has instructions to "tighten 3/4 to 1 turn after gasket contacts surface".
The Germans must have left this out on Mann Filters p/n
W 719/13 guess they are saving ink by not putting this
or any other instructions on box.
On filter 1)Apply film of oil on gasket, 2)Fit filter and
tighten by hand, 3)Fill up oil and run engine, 4)Check for
leaks, If necessary retighten.
3/4 to 1 turn works also.
Heh, heh just couldn't resist commenting on your comments.
