What is the difference between "regular #2 diesel and "light duty" diesel? A store near where I work has the light duty stuff for about ten cents a gallon cheaper and the little voice in my head tells me to suck it up and pay the cash for the regular #2 and up with the additives.

 

I've never heard of it.
Are you sure they are not talking about kerosene? It is called #1 diesel. Don't run much of it in your Cummins under load. Winter is ok in COLD weather. It gells at a lower temp.

 

I my experience, at least at bigger truck stops, they label the "light duty diesel" because it has the smaller nozzle on the end of the hose....where the "Regular" has the bigger nozzle for REAL trucks!!

there is no difference in the fuel [both truck pump and car pump come from the same underground tank, just different nozzle size] both are #2 in summer... once cold weather hits, they will switch to #1 [#1 is not the same as kero] so the fuel has a lower gel point so your fuel can flow without being heated..

now if it was off road fuel, if you are getting good offroad fuel, it is identical in every way to road #2 or #1 fuel other than color... modern off road equipment has identical engines to road trucks so you can't feed them garbage fuel... the color means no road tax on the fuel, so it is cheaper, but illigal to run on road, and fines for getting caught running it on road can be expensive

 

Isn't the price difference 'cause you are in AZ and there is extra tax on the Highway trucks but not on the "personal/recreational" use fuel?

 

In AZ the "passenger" fuel is .08c cheaper. If it isn't posted at the pump that it has the .08 taken off the price, you can go inside to get the difference.

True at Truck stops, not normally at regular places. Most local stations can't accomadate vehicle with over 26 K#gross anyway. At a lot of T/S they have seperate pumps (smaller nozzles as said above that take for ever to pump 30 gal) that carry the reduced tax price.

Thanks guys, it makes sense now why Flying J has a price listed on the street and the pump is always eight cents cheaper.
