I have a block heater in my Mountaineer, and since I am spoiled, I use it all the time....nice to have instant heat and defrost the windows immediatly...
Well anyways, at the start, the A/f is always 14.7ish, but I forgot to plug the heater in the other night,and it took several miles to get it from a a/f of 12ish.
I was amazed that the block heater was able me to go into closed loop so quickly....but makes sense. Not only is it making my interior comfortable, my gas mileage doesn't drop in the winter as much as it would w/o the heater.
just babbling of an observation I made....
