Some people pointed out windshield wiper fluid, which is about 30% methanol and 70% water, if you're lucky to find the soap-free variety.
If you have friends who are in drag racing you'll get pure methanol easily as well.
Ehtylene glycol is nowhere near methanol when it comes to performance in general. Glycol increases viscosity, surface tension, where methanol decreses them. And heat properties are way better.
