plug it in whenever you want.
its only a oilpan heater, not a block heater
you wont get operating temperatures that much faster because its just keeping the oil warm not the coolant as in block heaters
i went thru one winter w/o plugging it in cuz the heater cord plug was recalled, and didnt have time go in
started normal all the way down to -51f
the owners manual is kinda vague on whether the ctd has thermostat in the cord or not...the 1.4 gas DOES, cant remember if the ctd does or not....if it does, it doesnt turn on until 0f...otherwise its on when plugged in
when plugged in, theres no noise like a block heater, no light or anything...i can feel warmth on the tip of the dipstick when it is plugged in, so it does work.
im using 5w30 synthetic, i dont plug in until -5f, and not always, its just not that noticeably different
