I am using castor oil now. But I think that amsoil (2000 50:1) is what I am going to use. The castor 927 works good and is suggest by lots of engine builder's but if you have power valves I would not suggest mixing it below 35:1 40:1 or it just gums up the power valves to quick.

 

I've used Super-M and 927, they both work real well with low amounts of smoke. If you use the 927 and your gas sits for awhile, the gas and oil will seperate, so you need to shake it up, particularly when used with high octane fuels. As with the super-M, this will not happen. I run 110 octane with super-M mixed at 40:1 in my stroked Banshee and my 89 250R and havn't had any problems.

 

Redline is the only thing I would put in my motor.

 

I use Ipone Samourai Racing at 50:1, and it smells strawberry

 

what about with a quadracer? I hear 20:1 is the best protection for them, and mine croaked twice when I ran 32:1 with Bel ray H1R

 

Amsoil Series 2000 50:1

I'll put it up against any oil, any day

Amsoil Synthetics, for those who know!

 

I use Powerplus Castor/Synthetic blend in my 98 Lonestar Banshee.

Smokes little, burns great at 40 to 1.

I also like the "castor" smell it puts out!
