bronsin, interesting discovery. Who would have thought a little sheet of plastic would have made much difference! Makes a lot of sense though.

CTScott, good tip on the automatic A/C mod. I remember reading about that a long while ago, and promptly forgot until right now...

Well yeah plastic sheet = no need to defrost.

But block heater + not turning on the heat = cool light out in one block instead of one mile.

Thats a summertime or better warm up.

For short trips (5 mile) that might be huge for mpg.

And Im wondering if using the bh makes sense even in summer for more mpg?
