Could you run two stroke oil in the fuel and lubercate the top end of the cylinder to run a tighter oil ring tension to pull more vacume with a vacume pump? It would be a very ratio 1 part oil to 100 part fuel or some thing like that. Whats your take on this

 

If your engine still has the cross-hatching in the cylinders (IOW, the engine is still relatively new), youll already have an oil film on the cylinder walls to begin with. 2-cycle will just smoke, and cause excess carbon deposits on the pistons and valves. As for the rings, what are you trying to accomplish with the engine?

 

Im designing a Endurance type engine that sees 7000 - 9000 rpm for 2 hours or more. I wouldn't care if it smoked i just want the engine to last. I found some low carbon two stroke oil Red Line Two-Stroke Watercraft Injection Oil (http://www.redlineoil.com/product.aspx?pid=22&pcid=16). Would you still see high carbon build up if mixed it a very high ratio? Would the high revs keep it cleaned out? Could it cause detonation? Could i just be paranoid about it not getting enough oil?

 

Will two sroke oil lower the octain in fuel like regular oil will ?

 

There was some discussion about this on www.bobistheoilguy.com last year. I can't comment because the topic didn't interest me. You can search for it in the "Fuel and Fuel Additives" section.

 

I know the Mazda rotary guy run it ti help on wear.
