Hi @ all!
First of all i would like to compliment Andrew as i really enjoy the webinars!
As i learned that oil contamination can increase the risk of knock i am asking myself if the premixing of fuel with 2 stroke Oil in rotary applications will contribute to a higher chance of knock occurring.
With alcohol based fuel like E85 we often use castor oil due to its better mixing capabilities with alcohol.
As premixing is a very common thing with rotary engine, does it matter that much? Should the mixing ration should be kept to a certain minimum?
How would you go about premixing in drag applications?
Thanks for your input!

Yes using very high pre mix ratios can increase the chances of detonation. Regardless whether the oil is added as a pre mix or via the factory oil metering pump, some oil is required for the rotary engine in order to properly lubricate the seals so it's a necessary evil. Generally I would suggest following the advice of your engine builder about pre mix ratios.
