Metallic octane improvers (TEL, TML and MMT) have a negative effect in alcohols. They lower the octane and increase the pre-ignition sensitivity.
but I think it’s irresponsible to tell people “organometallics such as TEL and TML, have absolutely NO effect on the octane rating of methanol” when the addition of TEL to alcohols is cited in several reputable sources as causing preignition and abnormal combustion.

Well I strongly beg to differ.
The use of alcohols blended with all sorts of other compounds (including leaded aviation gasoline) was throughly investigated before and during WWII. Several NACA papers have been written on the subject.
During th 1930s and 1950s various racing engines used blends of methanol and leaded aviation gasoline. These included the Offy engine, CooperCoventryClimaxIndy, AutoUnion, MercedesBenz, Alfa Romeo, and the 1930 Fiat Aero record plane.
Quoting from one technical paper:
"The alcohols, not only do not detonate but also have virtually zero lead response, hence lead doping of alcohol blends with TEL and TML appears to be futile."

E85 is Ethanol and Gasoline. Ethanol and Methanol are different.
Now while Tuner & David are both correct. The bottom line is that there are much better alternatives than trying to mix methanol and racing gas so why waste your time
