off road diesel

[Doc_Bob]

As will I Bob. Mine needs..??..4.3 qts..to fill..and with my low hrs usage..Im not going to let oil sit in the crankcase for 2-3 YEARS..I mean GEEZE!!!

Double GEEZE! (Or was that double cheese?) Oil is cheap, repairs cost money. My tractor is my baby!

If you find off road diesel that has more than the current 500ppm of sulfer that the on road diesel has, it is extremely rare.

There is very little diesel making it into the system that has more than 500ppm sulfer. The 2007 standard will be 15ppm sulfer. For a while, that will be primary directed at on road use. Eventually, most if not all of the diesel will be 15ppm.

The only difference in on and off road diesel is the dye, which designates the fuel as exempt from road taxes. That dye is mixed in at the terminal when the fuel is loaded on the tanker truck. I know these things since I have delivered the product.

Diesel is ALL the same at the terminal (at least until advent of ULSD), the additives specified by the individual stations/users as well as any dye is programmed in at the time of the loading. It is cool to watch the various lights on different tanks turn on/off as the individual additives are injected into the fuel stream.

Just get the off road to save the money and don't worry about the sulfer content.

Yes.Yes coepie1. Most definite. DON'T worry!

If you don't use your tractor than you may want to change the oil every few years or hours per...which ever comes first...

I just change more oil frequently. Easy, relatively cheap (2 gallons) and satisfying to do.

Bob you just purchased your TN a month ago, just how often have you been changing your oil since you got it?

Bob you just purchased your TN a month ago, just how often have you been changing your oil since you got it?

Hahaha, I was going to say...???
I've had my tractor for 1 year and only changed the oil 2 times. Once at 50hours and just last month at 200 hours.

Any fuel above 500 ppm (parts per million) is high sulfur. Any thing below 500 pmm is low sulfur. Ultra low sulfer will be only 15 ppm or less. Thats what the new EPA standard will be. It is supposed to be available by Oct of this year,but will start showing up here and there anytime. Thats why you are starting to see pumps marked with what they are dispencing.Sulfur actually acts as a lubricant in diesel fuel.

Sulfur actually acts as a lubricant in diesel fuel

Not really, but since 2005 ALL diesel fuel has met the ASTM D975 specification for lubricity. ULSD also meets that specification. Hence, the reduction in sulphur should have no bearing on the lubricity of the fuel used in your vehicle. A non-issue, so to speak.

From the Chevron diesel FAQ site:

Lubricity is a measure of the fuel's ability to lubricate and protect the various parts of the engine's fuel injection system from wear. The processing required to reduce sulfur to 15 ppm also removes naturally-occurring lubricity agents in diesel fuel. To manage this change the American Society for Testing and Materials (ASTM) adopted the lubricity specification defined in ASTM D975 for all diesel fuels and this standard went into effect January 1, 2005.

The D975 specification is based on the High Frequency Reciprocating Rig (HFRR) test (D 6079) and requires a wear scar no larger than 520 microns.

Any fuel above 500 ppm (parts per million) is high sulfur. Any thing below 500 pmm is low sulfur. Ultra low sulfer will be only 15 ppm or less. Thats what the new EPA standard will be.

I don't know what is considered high sulfer, medium sulfer, and ultra low sulfer, but I noticed yesterday when filling my truck that there was a new sticker proclaiming the diesel I was purchasing as "premium #2 diesel with less than 500 ppm of sulfer". There also was a big sticker right under that saying "WARNING use of this fuel in certain 2007 diesel vehicles will cause serious engine damage".

What's that all about?

Oh yeah, it was nice to fill up and only have it cost me $112.50.

 

[SkyPup]

The 500PPM sulfur concentration warning you saw, Dargo, means that using the fuel in any diesel engine built in the year 2007 or later will destroy the catalytic convertor immediately, which will also lead to more expensive engine problems on down the line.

And by the way, Sulfur is NOT a lubricant.
