Just trying to help. Here is some more, too bad i don't have any exxon stations here, there would be a little more of a piece of mind..


Here is some more info about exxon fuels: FAQ

What is diesel fuel?
Diesel fuel is principally a blend of petroleum-derived compounds called middle distillates (heavier than gasoline but lighter than lube oil) and may or may not contain additional additives. Other middle distillates include kerosene and No. 2 Heating Oil. Diesel fuel is designed to operate in a diesel engine where it is injected into the compressed, high-temperature air in the combustion chamber and ignites spontaneously. This differs from gasoline, which is ignited in a gasoline engine by the spark plugs.

What specification requirements of diesel fuel should concern me and why?
Sulfur content, Cetane number (ignition quality), cleanliness, lubricity, low-temperature operability and stability are the diesel fuel requirements of principal concern to you.

With the introduction of the 2007 model year, diesel powered vehicles have to meet stringent emissions limits. The equipment used by vehicles to meet those standards depend upon a fuel with very low sulfur content, 15 parts per million (ppm) or less, referred to as Ultra Low Sulfur Diesel (ULSD). Use of LSD, with sulfur content that can be as high as 500 ppm, can, in a single tank full, permanently damage the emission control equipment of the new vehicles. We should note that ULSD is suitable for all diesel engines including those manufactured before 2007. All diesel dispensers have a decal on them indicated the type of diesel fuel being dispensed. Look for the ULSD decal for 2007 model vehicles and newer.

The cetane number is a measure of the ease with which the fuel is ignited in your engine. It is most significant in relation to low-temperature startability, warm-up and smooth, even combustion. The cetane number of the fuel should meet your engine manufacturer's minimum recommendation for the type of service. A cetane number higher than required does not materially improve engine efficiency or operation. Most engine manufacturers recommend diesel fuels with a cetane number of at least 40. Diesel fuels sold by reputable marketers meet or exceed this requirement.

Cleanliness refers to the absence of water and particulate contamination. This characteristic is important because dirt and water can plug fuel filters in your engine and cause severe damage to your fuel injection system because of the close tolerances within fuel pumps and injectors. All diesel engine manufacturers equip their engines with fuel filters to protect the fuel delivery system. You should replace these filters according to the manufacturer's recommendations. Some manufacturers also provide filters with drain valves and recommend periodic draining of any water that may accumulate from condensation and careless handling in storage or vehicle tanks.

Lubricity is the characteristic that ensures protection against fuel pump and injector wear. Since 2005 the use of lubricity additives has become common and all Exxon diesel fuels intended for over the road use contain them.

Low-temperature operability is the ability of the fuel to flow and to be pumped through diesel fuel system filters without plugging at low temperatures. Filter plugging due to the presence of wax crystals in the fuel can be estimated by measuring the cloud point temperature or other low temperature fluidity and filterability tests.

Stability is the term used to describe a fuel's resistance to the formation of gums and insoluble oxidation products. Fuels with poor oxidation stability contain insoluble particles that can plug fuel filters. This may lead to decreased engine performance or engine stalling from fuel starvation.

Is all diesel fuel sold at gas stations and truck stops in the U.s. now ULSD?
No. At present the EPA requires only 80% of the highway diesel fuel manufactured in the U.S. to be ULSD. Consumers may still find some LSD at services stations and truck stops until December 1, 2010 when EPA regulations will require all highway diesel fuel to be ULSD.

Does Exxon have ULSD available at all of its service stations?
No. At most Exxon retail locations where diesel fuel is sold, the product will be ULSD. However, some Exxon locations will still be selling LSD, particularly over the next several months as we make the transition from LSD to ULSD.

How will I know whether a pump is dispensing ULSD or the higher sulfur LSD fuel?
Federal regulations require all diesel fuel pumps to have labels specifying the type of fuel dispensed (except in California where all diesel fuel must be ULSD). Look for this decal.




What vehicles require ULSD?
Vehicles with diesel engines manufactured in the 2007 model year or later require the use of ULSD for proper operation. Using LSD or other improper fuel may reduce the efficiency and durability of engines, permanently damage advanced emissions control systems, reduce fuel economy and possibly prevent the vehicles from running at all. Additionally, manufacturer warranties are likely to be voided by improper fuel use.

How can I determine if my vehicle requires ULSD?
Instrument panel and fuel inlet/fill cap labeling is being mandated for 2007 and newer model year engines and vehicles that require ULSD fuel. Also, you can check yor owner's manual for vehicle fuel requirements.

Can I use ULSD in diesel engines manufactured before the 2007 model year?
Yes. ULSD is acceptable for use in all diesel engines.

I have heard that removing the sulfur from diesel can cause problems in older engines. Is ULSD going to harm the engine in my pre-2007 diesel vehicle?
Some of the sulfur compounds naturally occurring in diesel fuel provide some wear protection or lubricity. To compensate for the sulfur removal in ULSD Exxon branded diesel fuel is treated with additives to improve lubricity. Customers can be confident in choosing exxon because our branded ULSD fuel meets ASTM D 975 diesel fuel specifications, which provide standards for lubricity, cetane number and other performance characteristics.

I know that when we do an oil analysis it comes back with all kinds of stuff in it. I am still learning how to read those tests...I do think that they even break it down into the additives in the oil, because for example we have a local trucking company doing a test for us, they send the oil sample to thier lab, and we send a sample to our lab and compare results. THey have a 07 problematic ISX cummins in it and on the Delo LE the truck used a total of 3.5 gallons during a 21k mile oil change interval. We have them on a conoco phillips product called Guardol ECT with titanium now. During the first test on the LE, the truck was using 3.5 gal of oil on a 21k run. On a short service (10k), the truck needed 1.5 gal of oil. The sample come back as normal as it has been, meaning both tests said the same thing. On the titanium oil, on a short service the truck only used 1.5 QUARTS of oil. And on the 21k oil interval it use a total of 3 QUARTS, but the test actually showed 86ppm of titanium in it. pretty neat that the product tests like it is advertised. So i am thinking that ya maybe the additives can be filtered out....:humm:

Tinman - the king of cut 'n paste! Woo hoo! :choochoo:

Am I gonna trust XOM or BP, or Shell or any other big profit-driven oil company to make sure the right stuff is in my fuel?

With the EPA/govt. telling them what to do?

Uh, no. :td:

So Tinman, did you know that because of FAA regulation WRT the pipeline system, fuel adds cannot be introduced until the last terminal before local delivery?

i use powerserve in the white bottle in my duramax and in my john deeres aswell, last winter was a constant problem for gellin and that stuff did the trick

I run cenpeco in everything. Motor, fuel, front end, rear end, tranny. When i bought my truck was getting 18mpg, when i switched it all over it bumped me up 2mpg. This stuff is crazy take some time to look it up.

I don't care about copy and paste!
It's useful information provided by the knowledge of where to find it.
Great, that you allow us access to those informations.

The fog begins to clear!
Thank you!:tu:

first off umm duh. and second thing your the one demanding the proof. So show us where government tells them everything to do. But let me guess, its what you "heard". They do to an extent just as everything in life, but not all. I remember poor donny k gettin run through the ringer for proof.. Manufacturers for one thing are not going to come right out and tell the public exactly the processes and what additives and so on and so fourth to make up products. That is what I and a guy like Heath is for. A go to source for info, regarding certain products. So I am finding info that is publicly available to those who dont' want to research it and for those stubborn enough to admit when they have been corrected or are wrong. Did you know that Mobil offers a complete replacement warranty if something happens due to fault of thier lubes? How many other manufacturers do that? For the ones who care regarding the maximum filtration of oil well here is mobils recommendation and yes it is copied and pasted from my email. But someone still won't believe it... :tttt:

Mobil1 oil filters down to a nominal 10 microns, filtering any finer
than this can filter out the oil additives.--
Thank you for choosing ExxonMobil products.
If you need further assistance, please contact ExxonMobil at 1-800-ASK-MOBIL

Hey Tinman, is Lukoil same as Mobil? For some reason most Mobil station by me changed to Lukoil and most of the Exxon's around me don't carry diesel!! :dang: I'm going to see if I can find one next fill up!! Any word on hess fuels?

Yes, maybe in all your research you should try to find out how many times it has been successfully invoked. I'll give you a hint: It's a small number less than one. Many have similar "warranties" that are in all reality worth less than the paper they are printed on. Amsoil for one, has had several court cases over it through the years.

Maybe you should ask Heath about that? :humm:

The naivete seen here sometimes is remarkable. :w2:

Mr. Point, how many people do you know have filed for warranty through Mobil? At least when a customer buys through us the mobil rep and we make it right! :tu: Then again, failures due to Exxon Mobil oil, (not poor consumer application) probably is below the zero mark:yeah: By the by no lack of sophistication or worldliness on my part.

Just for the sake of driving this thread even further off topic.... :w2:

A motor oil warranty is about as useful as a tree warranty. Once it is established and running (growing), any catastrophic mechanical failure (death of the tree) especially in the case of a lube-related failure, can almost without exception, be attributed to lack of proper maintenance by the owner (failure to water or prune the tree).

Within the various classes and grades of lubricants there are virtually no measureable differences in performance or ingredients between the major producers. Sure they all tout their new, advanced high-tech formula, blah, blah, blah. Whatever. They are all doing pretty much the same things in slightly different ways producing nearly the same results within the same class/price point of lubricant. Premium labels like Amsoil and Schaeffers may be a little better for a lot more money.

Motor oil warranties are simple marketing ploys to get unwitting sheeple who don't know any better to buy the product. Nothing more. None has ever or will ever pay out on a warranty claim. That would be like trying to get the landscaper who planted the tree in your front yard five years ago to replace it because it died.

OBTW, this is a ridiculously assinine statement:

Mobil1 oil filters down to a nominal 10 microns, filtering any finer
than this can filter out the oil additives.--
