Fun Stuff > CHATTER
This even more just in - the weather thread
SubaruStephen:
My diesel Mercedes has a block heater despite the car being built for the Southwest, where it's unnecessary. Now that it's up here in the MidWest where it's useful, it's still unnecessary because the car is 30 years old and I don't drive it in the winter (I will not expose my baby to that nasty road salt)
What I do drive is a (surprise) Subaru equipped with an oversized AGM battery.

An undesigned hot spot in a combustion chamber is what causes detonation. Detonation causes engine damage.
Aziraphale:
Well, that was educational (seriously... I don't even drive and didn't know half this stuff. Thanks.)
bhtooefr:
To be fair, many (most?) people that drive don't even know the bits about gasoline engines, much less the stuff about diesels.

All I know is that I learned that my 24 year old car runs surprisingly well in the cold.
Despite my best efforts, I ventured into the white abyss and the -30 wind chills because a friend needed a ride.

Ah; a different term for what I called knocking.
