RE: Oil Change

["TERRY COX" <tccox@xxxxxxxxxxxxx>]

Something about penny wise and pound foolish.   Those aluminum washers are
very very cheap and meant to be used one time only.  I've been in the
engineering field for 30 years. Aint no way in hell I'd not follow the mfgs
advice for torque.  Those engines are just too expensive  .  And no the
aluminum washer does not hold the bolt tightly.....
