I have had diesel cars for about 25 years now and at times I ran Avjet-A in all of them. I have not experienced any problems. We sell Phillips Fuel which has Prist blended in it so I used it to control the crud that grows in the fuel tank. I noticed that my fuel economy suffered a bit as the kerosine is a lighter and does not contain as many BTU's per gallon. As a child I remember the busses around Idlewyld all used to smell like jet exaust so I guess they ran it there. I ran our fuel trucks and aircraft tow tractors at National Jets at FLL for years also without a problem, so I think a little kerosine here and there isn't a bad thing.
