i should hand calculate what I am getting for milage on the trip from NC to Maine and back....never really have and I know running 90 I get reallllll crap for milage compared to the 60 or 65...hah

 

I am running on ULSD.... all we get here also. But that is all I hav eran it on. On my 01', never really saw a drastic drop from lsd to ulsd. Just popped the reset button on the overhead for grins, running 69 back and forth, ran about 60 miles, overhead sitting at 15.6, calculate 14% addition.. 17.78... I'll take that all day. But before all the adds.. it was a DOG. Had to pull the PMT off for warranty work... thought I was going to get run over.. and sufferred huge on milage.

 

If you want a larger diameter tire that would not hurt the MPG as much
consider the 19.5 commercial wheels and tires.

You can see these factory installed
on the new Cummins 6.7 3500 Cab/Chassis Rams
showing up at the dealerships

 

i know this sounds like a retarded question but how do you know what fuel is being used in your area.. i live in NC and never even knew there were 2 different types of fuel..

 

one way is to look at the pump. . .there will be a sticker that will tell you if it is LSD(500 PPM sulfur) or ULSD (15PPM sulfur)

another way is to look at the foam, yellow tinted foam is LSD, white foam is ULSD.

 

o alright that makes sense know
yeah every where i got hasthe 15....so i guess its the USLD in Maine and NC

 

come down to georgia and you will still run into places that still sell LSD. the Flying J outside of Jackson on I-75 sells LSD where as the T&A across the HWY sells ULSD.

you can tell where I go instead

 

All I have been seeing around Arizona is ulsd.

 

what is the better stuff? the 15ppm or the other stuff?

 

LSD. . .it has a slightly higher cetane rateing and better lubrication from the higher sulfur content.
