This may get moved but because I am new, I was wondering what the difference is in diesel 1 and diesel 2 fuel is at the gas pump? Do not put #1 in your truck. It's basically kerosene.

It will run on it in a pinch, but #2 is the correct fuel.

Numbers 1 and 2 Diesel Fuel are the primary fuel for mobile diesel engine applications. Number 1 Diesel Fuel is commonly labeled at the pump as "Premium Diesel" or with a Cetane number of 44 or 45. It is not as thick as Number 2 Diesel Fuel and for this reason is the choice for motorists during the cold winter months. The disadvantage of Number 1 Diesel Fuel is that it does not have the lubricating qualities associated with Number 2 Diesel Fuel. While Number 2 Diesel Fuel has a higher lubricating quality than Number 1 Diesel, its thickness can cause rough starting in a cold engine and rough-running in cold weather. Number 2 Diesel Fuel is usually labeled at the pump with a Cetane number of 40

I've never heard of that before.:confused: Why would any company label a fuel with a lower energy content as premium?

:wtf1:

I have been using prem. diesel whenever I can. I thought it was supposed to be like #2 w/ additives in it already. Kinda like adding Power Service, Stanadyne, etc to #2. If this isn't the case and it is just #1 diesel:confused: , then I won't use it. I'll just add Power Service to my #2.

I'm not sure what Premium Diesel is. I haven't seen it before.

Find the fuel brand and call them. If it is #1, that's news to me.

:rolleyes:
Stopped at a truck stop last year that had "Premium Diesel" pumps so I went into the Fuel Desk and asked the clerk what it was since it was about 10 cents per gallon more expensive. The clerk had no idea and neither did the fuel desk manager. Who knows?

I know that they do use #1 D up north to prevent fuel gelling.

I thought that #1, #2 and Premium were all different. I seem to remember getting better mileage with Premium diesel, both in the Colorado Rockies in winter and down in Texas in summer. I try to only buy fuel from Shell truckstops the diesel techs in S.A. say it's the best in this area. I don't buy premium all the time, usually only when going long distances and as a treat for the engine.

premium is not #1, cetane point on premium should be 45-50, and reg #2 would be 40-45. that is why better mileage with premium(blend stock), fuel conditioners raise cetane and boost lub. lot of euro engines used to run on #1, not many american diesel tho.

:cool2: :thankyou2 ...I'll keep running it then.

AAAH YEAH!:exactly:

Also ALL DIESEL in the US has "VLS" (very low sulfur) < 500 PPM sulfur (reason for the new higher cost in the fuel, my opinion) in 2009 EPA will require sulfur to be < 20 PPM. I think we will see some big increases then. Transport companies are whining that their transport systems will need to be "overhauled" to deliver diesel "ULS" (ultra low sulfur) I know this is very bad news for all of us, I think we will see MUCH more Biodiesel. It already fits the 2009 requirements. "Information from Medium Duty Truck magazine and my uneducated opinion with a little help dear old dad the petrochemical engineer with 50+ years designing refinery systems - now retired (mostly)"

I work at a fuel company and #1 diesel is low pour(meaning it will not start to gell untill about -50C while #2 is heavier and will start to gel at -29C btw #1 is not baisically kerosine it is quite a bit heavier and it is fine to run in these trucks in cold weather applications it is just a good idea to add something for lubrication

arguy, sulfur was just a by product(carry-over i think they call it, like benzene the EPA has talked about removing also, but drops) premium has more parafin stock(wax, which gives slow burn energy). i believe if sulfur were to stay that it would cause erosion problems with high pressure common rail injection systems, not help. and transport companies i think complain about everything they can to keep politicians and the wan-a-bee's(EPA) from dropping the hammer on them. a member reported back in winter oil co. were exporting diesel to euro after filling tanks here to control market and get better price there(fill storage tanks and load rest on tanker to europe). i am not a chemist but had to know what i burned on my boats and aircraft in the service. the engines on one boat was desired to use #1 diesel back in the 80's. funny thing is people pick a brand to use, but if you find a fuel loading terminal you will see most oil company trucks loading at same time? i think that bio will probably be best for these engines and USA. were i grew up the peanut farmers used to give state scrap/waste oil to burn in truck during summer never heard of any problems and that was in 60/70's so its not new just better accepted. best.

Hi keith_2500hd,
Sulfur is a natural part of crude oil. I remember back in the 80's BP was having problems with sulfur in the Alaska pipeline attacking the metal. You are correct, sulfur is a bad thing and the EPA want's it out of the fuel. The article I was reading talked about the high sulfur content in the distribution system, and how it will be difficult to get the system cleaned up.
Bio is the way to go, algae is probably the best solution for the oil stock.
Thank's for the reply...

No choice here. In mid October they switch to #1, and in mid April they switch back to #2. We run an additive all year round. We did have an issue with the auxiliary fuel tank's filter in the bed gelling going down the ALCAN, but it was -48F, if not lower. That was with #1. We've never had an issues in town with gelling.
