[quote="jasinpa" never put gas in a diesel engine , gas has such a high octane rating, it exsplodes befor diesel will , you mys well through a handfull of rocks down that engine because thats what its like on them pistons , for gods sake quit supporting them[/quote]
The gasoline problem is diesels is when somebody pulls up with a near empty tank . Then fills to the brim with gasoline . The Diesel engine during hot weather in particular will have problems with a 90% charge of gasoline.
10-30% gasoline mixed with diesel will flow and start better in sub zero temperatures. Won't bother the engine in the least.
Octane? Diesel has a lower octane/higher cetane than gasoline. That is why all fuel engines have a lower compression ratio than gasoline engines do. Diesel ignites at a lower temperature than gasoline.
Gasoline does have a lower flash point and higher flame speed than diesel. Hence the knocking if a diesel is dosed with too much gasoline in hot weather.
Octane has virtually no bearing on energy content either in fact 87 octane has more btu's per pound than 94 octane.
I'll agree that Wally World has done North America more harm than good.
