i think even by using a different oil it would not totally solve my grind
probs. methinks it might be that the synchro for 3rd is gettin old.
but, i used castrol syntec because my friend did a torture test on one of
his demolishion cars. he filled his tranny with a leading brand of
synthetic oil and then drained it and ran his derbee. then after the rally
if the tranny was still motional, he jacked up the back tires and let it
run until the tranny seized. he repeated this four times with different
oils. they were valvoline, redline, castrol, and casite. valvoline seized
before the derby ended (which really pi**ed him off), redline ran for
around 45 minutes after the derbee, casite ran for only 5 minutes (close
call), and castrol ran for 2 1/2 hrs. he did this in hopes of being on a
commercial, and submitted his tapes of the whole deal to castrol. they
rejected his numerous tries saying the experiment had too many uncontrolled
variables.

anyways, thats why i used castrol. it came out on top by quite a bit in
this little test.
