Oil brands and synthetic vs conventional oils have plenty of opinions associated with them.
I get it, and that's not the direct focus here.
Typically 30 weight oils are what's dumped in predators and the likes, as I have done for years.
Stock or hopped up, 30w seems to be the "norm"
I see that ARC recommends at least a medium weight oil for their billet gx200/ clone type rods,
but NR racing says 20w for gx200/ clone's , and 30w for big blocks.
And some 4t kart type oils are sold in 20w.
So what yall feel bout 0w20 oil in their kart motor?
Less drag= more power? I tore down one of my predators, and noticed cylinder scuffing top and bottom,
the cam and con rod does not look great, and I don't care to reuse any of the motor parts. So just stuck it back together,
run it till the end. 12.7 :1 compression, 61mph @5500. Pulls wheelies. Upgraded cast rod and genuine honda flywheel from junk GCV190 mower.
I decided to try it, picked up 3qts royal purple 0w20, and going to run it from today on out with the motor, just to see
what happens.
Thoughts? Thanks.
