alright ive always noticed the labels and what not for the cetaine ratings and the ultra low sulfer yata yata, before the 08 or 07 change what was the fuel before? and where i fill up at the local hess its a minimum 40 cetane rating, and at the shop were we fill up the flatbed and the wrecker, it says 500ppm or somthing to that extenet, but the thing is...there fuel smells really bad, like it doesnt smell like fuel, its very strong. but i know its not bad becuase ive put 30k on our flat bed this year alone so far and we havent had an issue on the dmax ramp yet.
are these the same fuels just difference conversion numbers or something? like metric or american type of deal.
Cetane is basically like Octane, but for diesels... the higher the better.
the PPM is for sulphur content. Before the change-over it was around 50ppm of sulphur, now with the ULSD fuel it's about 15ppm if i remember right.
500 ppm seems like a really high number... you sure it's not off-road-only high sulphur diesel? It smells funny, usually has red dye in it. Wish I could run it in my truck but it's a $1000 fine if you get caught running it on the road
Can you still get the 500ppm fuel? I thought that even the off-road fuel is at 15ppm, now. People that I have talked to have told me that it's all the same with the only exception being the red dye.
if it's all 15ppm now what would the point of red dye be?
I know they are putting emmissions restrictions on all new on-road diesels now. CAT is stopping making on-road diesels this year. They didn't want to spend all the money to meet emmissions for 2010. Doesn't effect them much cause 90% of their sales are for off-road diesels

The purpose of the red dye is to mark it stating that this is off-road fuel, meaning that highway taxes are exempt from it. If you get caught with it in your tank on a highway vehicle you can face some severe fines.

what i'm saying is that before when the offroad diesel had higher sulfur content they used the dye to tell the difference.
if both the offroad and onroad have the same sulphur content now why would they still need to dye it?
Example, You go to fill your truck up and you have 2 pumps to choose from. One pump is 2.75 a gallon, and the other is labeled off-road use only and it's 2.35 a gallon. Which one would you use? Both fuels are the same. One has highway taxes added to it which is why it cost more. If you put the cheap stuff in without anyone seeing you, you just saved a lot of money. If a DOT officer decides to stop you and inspect your fuel, without the dye they wouldn't be able to tell what fuel you have. With the dye, you can't hide it. That is the only reason for the dye. The dye says this fuel is exempt from highway use since it has no highway taxes on it. If you get caught using this fuel in a highway vehicle, you will pay a steep fine.
the sole purpose of the dye is for taxes, origonally the fuel was 5000 ppm, thats why big trucks used to smoke like freight trains. then it dropped to 500 ppm for on road and offroad stayed 5000. then a few years back it dropped to 500 ppm across the board. then the last kick dropped it all to 15 ppm. to my knowlege the only place that runs the old high sulfer fuel is ocean freighters
