Off Road diesel

[JHardwick]

what does cetane actually do for a diesel?



I know that some equate octane with power in the gas world, but in reality it only allows for more compression before detonation ... ... ..... so, what gives with cetane?

JH

Cetane is to Diesel what octane is to Gasoline. Cetane enhancer is added in the blending phase of production and provides stability to the diesel and prohibit predetonation during the compression stroke.



49 state 40. 0 minimum.

(CARB Diesel) Calif only 50. 7 minimum . The CTD loves this stuff

JH if your ever in Ca with your truck you'll see what I mean. It really gets rid of the harshness and vibration, but nothing really noticable as far as power and econmy. I travel between Ca and Wa st often Or and Wa both use the EPA.

Wow, while relatively new to diesels, I've never even heard of anyone I know gettting their fuel checked. Maybe our california fuel is already so overpriced



Probably has more to do with fuel oil not being used for heating here. Except in the mountains, where they use propane theres not much diesel used for anything but automotive use here.



Good to know though, could come as a pretty big shock traveling.

Macdaddy - maybe you guys don't make it, but other companies do make 5000ppm HS offroad fuel.



Here is some info from BP's website.



Controlled Sulfur Content for Minimum Engine Oil Contamination and Engine Wear - Sulfur is a natural impurity occurring in petroleum products. Too much sulfur in diesel fuel can cause deterioration in engine oil quality by combining with moisture and forming acids. These conditions can lead to corrosion and wear problems. Amoco controls the amount of sulfur in Amoco Premier Diesel Fuel, HS Off-Road to levels lower than those specified in the ASTM requirements for off-road diesel fuels. Furthermore, this sulfur control, along with Amoco Premier’s superior ignition quality,

provides cleaner diesel exhaust with reduced levels of undesirable particulates.



Here's a link to the Premier HS pdf - http://www.bpdirect.com/pdfs/Amoco_Premier_Diesel_HS_Off_Road.pdf



Here's info on where premier is distributed - Available at selected terminals in IA, IL, IN, MI, and WI. Available in Low Sulfur, Low Sulfur Dyed and High Sulfur. In select terminals, Amoco Premier LS is available with a winterized additive for improved low-temperature performance



BP Diesel Supreme is simply better from the start. That's because BP Diesel Supreme is formulated from straight-run refinery stocks. BP Diesel Supreme offers superior performance with a minimum 50 cetane number, reliable cold weather starts, and long-term storage stability without sludge formation.



BP Supreme - Available at selected terminals in OH and KY. Available in Low Sulfur, Low Sulfur Dyed and High Sulfur.

There was a lot of sampling in northern California last summer, they targeted mostly farmers and construction.

I've been checked twice in northern CA in my Freightliner. Both times at scales, but it was IRS agents that did the test, :--) the CHP commercial officers were just there for enforcment. I've also seen them checking pick-ups in Nor Cal at a livestock auction,on a farm road in the Sacramento area, and at a rest area in the central valley.

Alright Light

It looks as though you've straightened me out. It is also clear that it is a regional blend that I was not aware of. My hats off to you for all your foot work. I am a DCS console operator and am currently running a 30 MBPD Diesel Hydrotreater our spec sheet calls our EPA diesel Blend stock 49 state EPA Diesel. I only know of our product and the marketing region that we provide for which sounds like the climate is a contributing factor when it comes to the off road diesel you mentioned. As you know the Gasoline, Jet and Diesel that we produce here in Ca has to meet the smallest target in the country I thought I knew it all.

I work at EWR airport in Joisey where there are lots of diesel powered equipment and big emergency gensets. Continental Airlines has two parallel 5kV gensets good for 3MW combined (V-16 Onan/Cummins). Not one piece of equipment is run on #2 Diesel. They use sumped Jet-A as it is no longer suitable for aviation use once sumped. They claim they use an "additive" to provide the proper lubrication to Diesel Fuel Systems... if it aint #2 Diesel, I don't know what they mean by "additive", LOL! I haven't seen a problem with any Diesel-powerd equipment in the five years I've been there. Maybe they're on to something. I wouldn't use it in my Cummins as I'm not willing to bet my bank account or my truck on a gamble, but there you have it.

I was working in the city on a job, driving my 5 ton International, a guy walked up showed me a badge and said he was checking for off road fuel. He checked the tank, everything was ok and was on his way. I never had up to that day, had anyone check any of my diesel tanks, kind of caught me by suprise!

 

[jsimpson]

[The fine is BIG! The station gets fined 10,000 too.

QUOTE=gravedigger]Yes illegal, people caught running it will be fined. [/QUOTE]

 

[jsimpson]

Not always true. Offroad diesel is dyed but offered in two grades typically - low sulfur and high sulfur. Some folks still get the high sulfur stuff for tractors and farm use. On road diesel and offroad low sulfur are in fact the same thing, the latter just having red dye. High sulfur fuel would be bad for your CTD.

Assuming no cat, why would high sulfur fuel be bad for a CTD? I remember a great deal of concern about CTD reliability when low sulfur fuel was mandated.

 

[jsimpson]

If you're operating on public roads, they have the right to ensure that you've paid the requisite fuel tax to do so. Those that run off-road fuel are using our public roads but leaving it up to those of us who pay the fuel taxes to build and maintain the roads. Does that sound "right" to you?



Rusty

And it's right that we're paying the 18 wheeler tax rate even though we are not impacting the roads nearly as severely???

does "probable cause" or "warrant" only happen on NYPD Blue

Haaa... only the guilty are innocent until proven guilty... or something like that! :-laf

When you sign up for a CDL you sign away certain rights like they can search vehicle without warrant. You must submit to breathalyzer, drug testing in event of accident and a few other rights you give up in order to get right to drive for a living with large weights on US highways.

 

[WyattEarp]

Well as we all know farm fuel is illegal but im sorry to say but our heating oil that we used to get, same truck, same tank, same fuel as the off road diesel down here.

I found out because i asked, they just up the price on the supposed heating oil, ie diesel fuel. But instead of being red dye it was a pretty purple color . As far as the IRS/GOV't is concerned i have no good words for any of them, unless it is : "Bite me" end quote. its not that im cocky at all, its that im tired of being ran over by those ignorant, arrogant,_________. Used your imagination and fill in the blank LMAO

Beside only in a country where they have the majority believing there free when were really living under a legalized form of communism. Some may disagree but this is my opinion...

I do know also that down here you can run Farm fuel in a truck as long as it is strictly run from farm to farm or out in the fields and nothing else, basically either a honeytruck spreader or beater truck, as they have done away with the farm use vehicle in Va. if you use a truck as such you must now have insurance on it the same as a regular private used vehicle.

 

[LightmanE300]

Macdaddy - I'd trade being right 100 times to have all the good diesel you guys do Interesting how different regions have different quality of fuel. In general, the diesel around this area is terrible, barely 40 cetane, high aromatic garbage truck fuel.

 

[CRuth]

Well I guess I better be ready to be checked. Not that I'd have a problem, I don't even know where to get dyed fuel around here. I do think I'll go get a locking gas cap though. Hate to have someone play a little trick on me.

 

[bkroupa]

I heard a guy talking about the red fuel additive/preservative "Stabil".

He carries a half empty bottle around with him & using it, is why his fuel is red.

Just dont tick off the guy next door. He could put a quart of ATF in your tank and then you too will have red fuel for aboyt 7 to 10 tanks. .
