I was wondering what people who store their cars for the winter or drive them infrequently do in regards to their methanol/water/alcohol injection systems? Do you drain everything out and purge the pump dry before storage? If so, does the pump need to be primed after re-filling? Is it ok to leave a 50%methanol 50% water mix sit in the tank over the winter as long as it doesnt freeze up?

 

i was wondering this as well. especially for full methanol mixes.

 

anyone have any knowledge to share?

 

i guess no one does. i would think the best course of action would be to empty the system of the meth or meth/water mix and then fill it with some windshield washer fluid. this ways its not as corrosive to the parts, keeps the pump pieces primed, and won't freeze. anyone else with ideas?
