What advantage is diesel for a passenger car

Yes, I'm being sarcastic. Petroleum refining is a bit more complex than adding a quart of motor oil to kerosene. The aviation industry covers its ass thoroughly. There are a few diesel aircraft engines and the question comes up. The problem is diesels require a certain cetane (similar to octane in gas engines) rating. Turbines don't require cetane, only compression engines, so A-1 has no specification. It *probably* has sufficient cetane but nobody is going to stick their neck out.

I hate to feed your fantasies but there is one DIY blend but it isn't recommended. #2 diesel has paraffin and will gel as the temperatures get below freezing and the paraffin starts to crystallize. Most northern truck stops have winter blend, which is a mixture of #1 and #2. Some in places like North Dakota have pumps with straight #1. However if caught short with a tank of #2 on their way to Fargo, the old timers would add a gallon or two of gasoline to the tank.

You are talking to a former airport fuel truck driver who actually fueled aircraft on the apron.

I know the petroleum refining process. I am talking about adapting the kerosene grade or gasoline grade of fuel to run properly in a diesel truck engine. You just don't want to accept real life knowledge that you don't know off.

Every competent person knows that you can increase the octane by adding alcohol, and decrease the octane by adding motor oil. I am not talking about what the refineries do in their distillation process.

Our airport fuel trucks never left the airport property to get diesel fuel from a gas station outside the airport perimeter. This is their standard practice since the beginning of time. Do you think you'd know better than me what aircraft fuel truck drivers use to fill their own trucks' diesel fuel tanks?

You should read properly before your expose. I am talking about converting a very clean grade of kerosene (Jet A1) to use in a diesel truck engine. If the Jet A1 is clean enough for aircraft, then it is clean enough for a diesel truck. The trick is to add motor oil to lower the octane to diesel fuel level.

Not sure about NOW, but in the past a lot od it was taxation - and related to that, price. When I was in Zambia I knew a guy who drove an old Morris Minor around Livingston but also had a 5 ton Morris Diesel lorry. If he was headed for Lusake he'd load the minor onto the back of the 5 ton and unloadit to run around town in Lusaka, then load it back up to come home. Cost less the run the 5 ton oil-burner up and back than the 1000cc Minor - - - -

How far ?

Ever hear of google maps ? :-)

Useless when we don't know how far he was from Lusake
