Newbie seeks mixture assistance.

Hi there

I have been running a System 1a for a few years with a 25% methanol/75% water mix for antifreeze purposes. I'm wondering about putting in a higher concentration of methanol but am unsure of the benefits and/or problems.

IIRC, I read somewhere on this forum that above 50/50 shortens the life of the pump seals and again, IIRC, Richard Lamb once told me that anything over a 40meth/60water mix actually reduces the efficiency of the mix.

All suggestions welcomed. TIA
