I run the K&N oil filter it has a hex head so when you take it off its super easy. I coupled that with a magnetic add on that clips to the filter to keep all metal shavings in the filter and a Greddy magnetic drain plug.

Amsoil is the first in synthetics and I use in all my cars engines, transmissions and differentials. Google amsoil vs *any oil brand* and you will see it annihilates the competition.
while the "series" might change, this has been a good rule of thumb for awhile. from best to worst starting points of oils...(not all shown). oil reports will tell what "annihilates" the competition.

The best base stock is Polyol-ester (Redline & Motul)

Next best is Di-ester (Royal Purple, Amsoil, Neo)

Next is Polyolefin polyamine (Mobil 1)

Next is Hydrocracked (Syntec, Valvoline)

And finally, regular dyno oils.
