last time i tried to start it (was 40* warmer BTW) I fried a batt cable (cheapest american 4GA i could get

)
Something to be said about cheap people spending the most...
Anyways I HOPE to finish the damned 1GA cable up soon, just got kinda backburnered...
SO, what needs to be added to a tank full of summer fuel for it to start in the winter? Also what the heck should I do to the rest of the car?
srry for the hijack
