    Engine block heater for gas mileage

    I was thinking about gas mileage and when you loose the most and realized it's when the car is cold and running in "open-loop"

    So, as a solution you could install a block heater and plug it in before you drive(use a timer), even in the summer. This would preheat the water and minimize the time that the engine is running rich and save gas. Whatcha think? :wink:

    id imagine it wouldnt save too much gas and probably wouldnt be worth the expense, but hey, why not :)

    well, atleast I wouldn't have to go easy on the engine for long.. it's hard not being able to rev it to the sky right after you start and it's ice cold :oops:

    Using the block heater in summer is not worth it. You'll pay way more in hydro just for achieving operating temperature a couple minutes sooner.... and please abstain from redlining your engine till it's fully warmed up. :!:

    Using a block heater in the winter would be a BIG help. Fuel enrichment goes WAY up when temps are below freezing. My gas mileage has dropped WAY low this winter - to around 28mpg. That's down from 35 typical.

    FWIW, the ECU factors intake air temperature into the injection pulse width. There is NO correction @ 68ºF. It adds fuel below that temp and reduces fuel above that.

    I called Toyota about the block heater for 03+ Corollas (not sure about 98-02). The block heater is manufactured by a company called Pyroil. It is part # 00213-00885. My dealer had a little trouble finding it, so if you want one, that's it. They said the price was $55 and you have to pay freight for it, so it probably would come to around $70.
