I've heard of them for old cars, but can I get one for my 89 SR5? I'd really like to heat the oil than starting it dry on negative temperature days!
What do you mean by "good" to -18C?? is that how cold you can use them and then it becomes too thick?Flashmn said:Wrong. Not all of the oil settles in the oilpan. Alot of it is still in the head and other parts of the engine, and it will stay there.
IF the engine would dry during the night, it would quicky become very loose as friction between metals would wear it out very fast.
10W- oils are good to -18C
5W are used to -30ishC
And military trucks here have a holder for a gas blowtorch to heat the oilpan.I once saw a magnetic heater you could stick on your oilpan,
The average temperature of Vermont is quite a bit colder than the average temperature of Anchorage, Alaska.mr.kenny said:I see you live in Finland. It is very cold there I am told. A block heater is probably widely used in Finland; but I wouldn't know. In the U.S. it doesn't get nearly as cold as Finland, so you rarely see block heaters being used except on diesels and in Alaska.
In a perfect world engines would be warm and last forever; but we live in the USA.
Usually synthetics are all we need on aircraft, high performance engines & anything we want to start in the winter.
