Listers, just another 2cents. The Public Broadcasting Network's Motorweek
show (segment Pat Goss of Goss' Garage) showed the same mixing test a few
weeks ago and recommended the Isopropyl over the Methanol for the same
reasons. (Look for "dry gas" products and read the label - some contain
methanol and some Isopropyl.) I remember reading the same thing about 3
years ago in an auto magazine. And it has worked for me.
Also keep the tank filled as much and as often often as possible (without
driving yourself crazy). This prevents "sweating" of water vapor on the
inside walls of the gas tank. The "dry gas" soaks up any water that may have
condensed in the tank and gotten into the fuel system. Cheers.
