Default How often

Hi Guy's I was wondering how often you should change oil in all 3 holes ? I use Lucas syn in all 3 with the syn stabilizer so I change the engine every 5000 and was wondering about the other 2 ! Thank you for your valued opinion ! JT

I change all of my fluids at the same time, every 3000 miles....it is probably overkill but I feel better changing them often.

I change all three every 5K miles. I run Amsoil 20-50 motorcycle oil, and I just order it 5 qts at a whack along with the oil filter. The extra two qts for the trans and primary aren't a big deal and it only adds a few extra minutes to the oil change time.

I do all three every 3k miles. I run Amsoil 20w50 in the engine, Amsoil ATF in the primary and Amsoil 75w140 gear lube in the trans but that might be a coincidence since I'm an amsoil dealer

FYI I had alot of valve train noise when I tried Lucas and my cams arent agressive.

I change all 3 every 5,000 miles. I use Mobil 1 20/50 in engine, formula + in primary, and mobile 1 75/140 in tranny.
