I know this has been on here before and I ignored it. I have used nothing but HP2 but I love the smell of the Klotz. Whats the genral opinion on Castor vs Synthetic oil?

 

I run nothing but Maxima castor 927 in my machines.It is recomended by most performance shops to run in their motors.I never fried a piston using it and can go 2 years between rebuilds!

 

I am a fan of MC-1 by Bel*Ray. I used castor oils in my YZs and while I had good luck with them, they seemed to gum up my power valves super fast. I run the synthetics in my bansh now and am having great luck with them.

PS---------- Dont base your oil on its smell man!

 

Didn't mean to make it sound as though I was gonna
run the stuff just because of the smell. I was just curious how it could offer better protection than synthetic. I have heard that it will gum up powervalves but thats sure not a problem on the old honda's. But if it does that it probably don't
burn as clean as synthetic, right?

 

My pistons,cylinders and exhaust dont have any build up at all,it burns very clean in my experience.I run it at about 40 to 1 ratio.I'm sure you will get good results with any quality oil castor or synthetic.A clean air filter is what matters most for long engine life.
