I have been reading about methanol injection and have a question for anyone that has experience with it. How many miles do you usually get out of a gallon of boost juice (or whatever meth mixture you use)? I know that milage will vary, but I can't even seem to find a ball park figure.

 

I don't run meth on my car, never have, so take my input with a grain of salt... I'm not so sure you'll get a consistent response. I would think mileage would depend on how often you get into the high boost. If there is a boost threshold when it comes on, keeping it under will slow down the usage. Get into it more often, and it will run down faster.
