Re: Warming up the Engine, OE+ filters
Thanks for the interesting info you have provided. Aircraft engines are
air-cooled, however, and I imagine the engine heaters heat the oil, which
could release moisture and acidic combustion byproducts.
Auto engine heaters (the good ones, anyway) heat the coolant and should
not result in moisture and corrosion problems. The engine doesn't actually
get that warm, at least not at the temperatures I use my heater (<-30).
Given the choice between an engine heater and starting my engine at -40,
I think I'll take the engine heater. The engine wear on initial start at
these temperatures can be high (if it does start, that is). Three years ago
we had a spell of winter where the daytime high didn't get above -30 for 6
weeks, and I blessed my engine heater daily.
