When I was a kid I put some diesel fuel into my dad's car. It wasn't much, but it WAS enough to make is run like crap...AND enough to get a beating.  |
Octane and cetane. Sounds different yet I means the same. Waters ability to remain liquid at cold temperature or waters ability transform to solid. Not the best argument
