I found some interesting document about the way that diesel fuel is shipped and I'm going to share these document with you... http://www.arb.ca.gov/regact/dieslub/notice.pdf <- Some information on how diesel fuel is now shipped. http://www.arb.ca.gov/regact/dieslub/hor.pdf <- More on how diesel fuel is handled. http://www.ncagr.com/standard/diesellub ... r11504.pdf <- How North Carolina is handling diesel fuel. Basically diesel fuel after being refined is well above the 520 HFRR rating which is unacceptable by any standards. So its up to the delivery personal to add the lubricant package to the truck before delivery. Currently I cannot find anything that insures that said delivery of diesel fuel will comply with the HFRR 520 limit. As far I see there is no test of the fuel after its loaded on the truck to insure it is within compliance or if the additive package was even added. Like North Carolina is saying "It is our understanding that currently 40% to 60% of the diesel fuel supply meets the new standard without the addition of a lubricity additive." Now how are we as consumers to be sure that the lubricant package was used when its needed? I'm sure the delivery personal are not testing every truck load of diesel before it delivered to your local fuel station. RAW DIESEL FACTS - BEFORE A ADDITIVE PACKAGE Ultra Low Sulfur #2 Diesel by law cannot contain more than .0015% (15 ppm) of sulfur. This fuel will generally have an HFRR rating of 600-800. Ultra Low Sulfur #1 Diesel by law cannot contain more than .0015% (15 ppm) of sulfur. This fuel will generally have an HFRR rating of 700-900. Remember: 1000 Microns = 0.039369999999999995 Inch As you can see above raw untreated USLD diesel is well outside the range of the 520 HFRR limit. It requires a additive package. But once again the is no regulation that insure that package was added to the truck in proper quantity for that load. Now saying this... I know there isn't a single diesel additive product on the market today that can promise to improve the diesel fuel lubricity below 520 HFRR level! Especially if its untreated diesel fuel with a HFRR value of 700-900!!! Just something to think about when you buying a fuel additive. But I know that 2 cycle oil is reducing that number for sure!

The easiest way to remember mix ratio for 2 cycle oil for your truck is 1 ounce of oil for every gallon of fuel. So basically if you put 20 gallons of fuel in you need 20 ounces of oil. This will work out to about 128:1 ratio which is very safe to use! Just for information purpose. Cummins authorizes up to 5% of WEO (waste engine oil) to be blended into diesel fuel. Knowing this now you can add up to 1.75 gallons of 2 cycle oil for a 35 gallon tank. But I would only stick to using 2 cycle oil and mixing 1 oz of oil to 1 gallon of fuel...

I'm still researching products and more research I'm doing the more I keep finding that diesel additive are using mineral spirits, xylene, naptha as a anti-gel and/or certane booster. But remember these chemical are NOT lubricants. I'm also finding that some of the chemical that they are using in fuel conditioners are cancer causing and have high health hazards. Like I told one user on Cummins Forum I've got a whole gallon of Xylene in the shop for paint thinner but I won't add that to my diesel fuel!We are trying to find additives to add to our fuel that contain lubricants and not thinners. With the on set of ULSD and lack of lubricants it has the last thing your injection pump wants is more thinners. The whole idea is to put more lubricants in the fuel. I got to admit all of the above chemicals would break down the waxy chains of diesel fuel and improve the pour point. But It comes with a price of enhanced wear on your fuel system. So far I haven't found any kind of product that is like 2 cycle oil for properties.

More Information on ULSD... First, I want to concentrate on the loss of the sulfur and why this is important to you. Sulfur is an Extreme Pressure (EP) lubricant. It is regularly added to lubricating oils and greases to increase the lubricity and to raise the amount of pressure that the lubricant can handle before the lubricating molecular barrier begins to break down. Sulfur has always been a vitally important factor in providing lubrication to diesel engine fuel pumps, fuel injectors, and to a lesser degree engine valves. The reduction now being made takes on-highway diesel from less than 500 ppm to less than 15 ppm, which for all practical purposes eliminates sulfur as a lubricant in the fuel. There are several methods of determining lubricity in fuels. The most common are: Ball on Cylinder Lubricity Evaluator (BOCLE), Scuffing Load on Ball Lubricity Evaluator (SLBOCLE), and High Frequency Reciprocating Rig (HFRR). The HFRR has emerged as the world standard and has been adopted by the ASTM and all of the engine manufacturers as the de-facto standard for measuring lubricity of fuels. HFRR ratings are counter-intuitive with the lower number showing better lubricity than a higher number. On an HFRR test the number given is a measurement of the scar diameter (microns) produced during the test. The larger the scar diameter, the lower the lubricity, the smaller the scar the better the lubricity Here is a few ASTM HFRR Standards... In the matter of Lubricity the ASTM after many years of discussion, has set its standard at HFRR 520 for diesel fuel as a minimum. Amount of lubricant in diesel fuel at 1 Gallon and 35 Gallons of ULSD diesel fuel. When you look at it from this stand point the amount of lubricants have been reduced to next to nothing.

Introduction I've been adding 2 cycle oil to my diesel fuel for the last about 20,000+ miles. So far I've found out that it has improved a few things like engine noise is reduced, fuel mileage increased slightly, and knowing the the fuel system is being lubricated is always a plus! I've been adding a quart every time I fill up with fuel. So if I pump 20-25 gallons I'll add a quart of 2 cycle oil. It makes it roughly 80:1 to 120:1 ratio of fuel to 2 cycle oil. This is relatively low ratio and with not cause any harm engine as far as I known. There is another reason why I'm adding 2 cycle oil to my fuel. It because of EPA changing the sulfur levels in the diesel fuel. This will reduce the lubricity. Knowing that VP44 injection pumps are a touchy subject you might as well add oil to the fuel.
