Mike, I have a question for you about diesel fuel a friend of mine at work wanted me to ask if there are good and bad brands of fuels for diesels, like there is in gasoline.

 

Hi K.,

Excellent questions, and unfortunately I know next to nothing about diesel fuels, other than there are a few grades. Most diesel vehicles these days run on good old #2 diesel. Diesel fuel is rated by it's "cetane" number, but by and large, this isn't an issue that diesel owners generally need to worry about, they simply fill up with whatever is at the diesel pump, and drive away. Most gas stations do not offer multiple grades of diesel fuel, they usually offer straight #2 diesel and that's it, as that is what most diesels require. Now of course big truck fueling stations have different grades available sometimes, but those are used primarily by 18-wheelers, not the kinds of diesels most of us would drive these days.

Diesels are of course compression combustion engines, where the mixture is ignited by the sheer amount of pressure in the cylinder/combustion chamber, so their fuel requirements are far different from a gasoline spark-ignition motor.

I just can't tell you anything about different brands of diesel fuels, or much of anything that would really be helpful or accurate, I'm sorry, I just don't have that knowledge.

Perhaps someone else here on the boards will see your question and be able to provide an intelligent answer?
