I tried it once, didn't do anything for my motor.

I know, but recently I paid an insane price for 50 cetane fuel.... Got 25.49 mpg vs my normal 24.90 mpg....... Not worth 15 cents/gal.......

in reality, I really don't think these engines care as long as it's liquid and oily and burns.........

I only run additive as a ULSD protection...........

Ahh the smell of Diesel Fuel, it's like coffee in the morning!

My Car:

I have been getting around 26.5 avg,

after putting in a half a bottle of the small Diesel Kleen, I got 29.5, my best fuel mileage in the last 12 months (same commute, no changes)

The bottle is like $6 a bottle, so $3 worth got me around an extra 45 miles on the tank. One gallon of gas is around $2.75, so it did pay for the bottle, and gained about another $2.50 or so....

i put a bottle in my tank when the car goes into storage for the winter... i dunno if it does anything or not but it starts right up

I think I'll stick to just plain ol' clean diesel instead.

Really?? Whats the alcohol content in 4-6oz (recommended dose) mixing with 17 gallons of diesel fuel, i wonder.

And y'all buyin those itty-bitty bottles, splurge and get a gallon at/near $20 from truck stops for cryin out loud. Dont pig out on the stuff and it'll last you couple of months. Just add 2 sec. splash everytime you fill the tank, thats all it takes. Those adding 4x-6x doses like an entire 32 oz bottle are probly scorchin valves seats and wearing down injector tips. Even worst, the overdosing crowd risks scorching bores, pistons and rings by diluting bore lubricating qualities of regular diesel fuel from the equation.

DK additives are excellent stuff, been giving each tank the 2 second splash treatment for years. I keep a gallon under the hood behind the windshield washer bottle - jammed in there next to a gallon of synthetic oil.

The Kerosene in D1 probably reduces lubricity FAR more than a few oz of Diesel Kleen.

I had to call the Power Service Diesel Kleen people to find out what the heck their bottle means. I have no clue what cetane is, and they didn't say how much to use per tank, or per gallon or anything. The large bottle also has no way to really dispense it into your tank.

But the guy said to put 4 ounces in per tank (mine's 15 gallons), or double that if you want more cetane and quieter running car.

As to savings on fuel, he said I'd get about 5%, because it makes the fuel explode quicker and easier or something.

If you ran pure diesel kleene thru your IP then yeah, I can see it effecting seals in some miniscule way, but when you add maybe an ounce to 82 litres of fuel, then I think the bad effects are greatly overtaken by the sheer amount of diesel fuel. My 2c

You know that Diesel Anti Gel addatives are almost 90% alcohol based?

Yeah but Kerosene itself has lubricating qualities thats why painters use it for cleaning brushes - it leaves oily residue and never dries completely. Evaporation rate of solvents i think determines the level of lubricity they rob from Diesel fuel. For example, fast evaporating acetone is probly the worst thing you could throw into fuel tank - sure it'll make heat up engine performance though.

I saw 50 Cetane fuel in Virginia last weekend and it was way over 3 bucks a gallon. I put in 5 gallons worth as I was near empty. The car ran great, at least until I found another station with crap diesel for 2.89/gallon.

As I said, I have been trying the Lucas Fuel Treatment ever since reading about it in "Star Magazine" at 3oz./tank, it seems to help. The DK goes in at about a three count pf pouring into a funnel. I get at least ten tanks per gallon bottle. I have been running it since we went to ULSD so I do not know what it is doing for my mpg.

I had a rough idle when I first got my SD. I used the lucas fuel treatment for a couple of months at the recommended dosage. Fuel economy went up around 3 mpg but didn't lose the rough idle until I started using the diesiel kleen. It didn't happen overnight but she's as smooth as silk now. I use the recommended dosage of 1 quart to 300 gallons of fuel but haven't noticed a difference in fuel economy. Don't believe I will ever have to do a diesiel purge if I keep using it.

I wrote to the guy at Diesel Kleen, he says.....

Cetane is a very powerful energy compound that helps the fuel to ignite
a split second sooner which helps the fuel burn more completely, reduces
engine knock and helps reduce emissions.

The Department of Energy, Clean Cities Tennessee and Wal Mart
Transportation all conducted their own testing using their own equipment
and test set up and they found that fuel economy did improve, usually
around 5% for mix fleets or vehicles, that emissions went down and the
vehicles had better performance. Clean Cities TN also ran NOx emissions
and found that Diesel Kleen reduce NOx by 9% (running) to 28% (idle).
Total Fina did a study with new injectors and found that when using a
strong detergent and strong Cetane Boost fuel economy increased 2%.

you must come to the GTG



Diesel Kleen is good stuff... my milage dropped by 2 mpg with the ULSD so some DK every full tank has improved my milage.. I average around 24-25 mpg ... 1,000-1,500 miles a month as well (takes about 17 gallons to fill with the R light on)

full tank with Diesel Kleen will yield me 430-440 miles til the R light comes on.. I always fill when that comes on

Cetane number or CN is a measure of the combustion quality of diesel fuel via the compression ignition process. Cetane number is a significant expression of diesel fuel quality among a number of other measurements that determine overall diesel fuel quality. Cetane number is actually a measure of a fuel's ignition delay; the time period between the start of injection and start of combustion (ignition) of the fuel. In a particular diesel engine, higher cetane fuels will have shorter ignition delay periods than lower cetane fuels. Cetane numbers are only used for the relatively light distillate diesel oils.]

Cetane is an alkane molecule that ignites very easily under compression, so it was assigned a cetane number of 100. All other hydrocarbons in diesel fuel are indexed to cetane as to how well they ignite under compression. The cetane number therefore measures how quickly the fuel starts to burn (auto-ignites) under diesel engine conditions. Since there are hundreds of components in diesel fuel, with each having a different cetane quality, the overall cetane number of the diesel is the average cetane quality of all the components. There is very little actual cetane in diesel fuel.

And where is this test result? Did they do it in a controlled environment? Can they duplicate the results?
