Here's a good story about how we find out what works and what don't. We were playing on the dyno one day. I did my research and I decided I was going to try synthetic 0 weight oil along with a few other things. we broke the motor in and fine tuned it. put 0 weight oil in and made a run which looked promising. made a change in jetting. made a second run. lost allot of power. jetted back to where it was and made another run and the death breath started huffing out the breather. bore was good. rod bearing wasn't. cut the crank , new bearing and back together for the next weekend. that was around 13 years ago. no more 0 weight oil here. but there are gains in light weight motor oil. you just can't get greedy and go overboard
