Hey guys, I just rebuilt my 12a and decided to go with premix. My dad used to race motocross when he was a kid and preaches about this stuff called Blendzall. It's supposed to be a castor bean oil that works really well and smells really unique.

So, have any of you guys ever heard of this?
If so, would it be safe to run this as an alternative for 2 stroke oil?

Here's a link to the site.

Thanks!

 

It's been done before, and it works. Just don't even think about putting synthetic 2 stroke oil in your tank though, the two oils will react and gunk up your fuel system.

I've always had good luck with castor oil in smaller 2 stroke engines over full synthetic. I did an experiment with two old identical model airplane engines, one running on full castor, 20% nitromethane, and the other on full synthetic 20% nitromethane. both of them running with a flywheel instead of a prop, and no cooling air, the Synthetic engine got up to 500 degrees on the cylinder head and popped, head deformed, upper end of the connecting rod failed and the cylinder wall had deep gashes in it. The engine running on castor oil never quit, and had no damage to it, and couldn't get it as hot. I've been told that the reason for this is that the synthetic oil evaporates at high temperature, while the castor oil tends to get really thick with the heat and add protection. I didn't learn my lesson, and years later ran my go-ped on Repsol full synthetic premix (25:1) and ended up blowing the motor because of it. I did run a two stroke on Protek R premix though, and never had a problem with it.
