I add about 8 ounces per fill up. On the initial time, I added about 16 ounces and then the next time was about 12 ounces and then 8-10 ounces per fill up.

I just found out today more about this stuff and what it does. On the bottle it said it lubricates the injectors. I didn't know they needed lubricating, but found out today from a diesel mechanic that they do need lubrication and he told me all the reasons which I now can't remember them all.

He said what this stuff does, it cleans all the injectors, and it keeps them clean and working like new. It also cleans the combustion chamber. And all the valves, gets rid of carbons that build up inside there.

It is also a Cetane Booster and bunch of other stuff. Mixing like I do, I get the extra 6 points so my Cetane should be about 56 or 57. I also run premium diesel fuel - religeously (spelling don't look right)

I told that diesel mechanic I didn't notice a real improvement right away, that it took about 350 miles or so. He said that was because it was cleaning everything inside. And that it should have been a gradual thing, which it was.

My W115 240D used to produce some large black clouds of smoke! I am talking those clouds like some semi's put out! You know where it blocks the sun and you have shade for a bit? :-)

No more clouds of smoke and the car actually runs better now.

The bottle is a silver color, the label is Black and Red and some white. Black cap.

Apparently a lot of farmers in this area like it a lot too, cause A-1 Truck Parts now carries a min. stock of 10 cases of the stuff!
I was in there one day buying my couple quarts and a guy bought 2 cases!
He said it was the best thing he's ever found for his motors. So obviously some people have tried a lot of things before finding Diesel Kleen.
I will swear by it! And you will too once you see the difference! I am thoroughly impressed.

I don't know what the difference is between Diesel Supplement and Diesel Kleen, but what ever it is, I am a firm believer! And they are both made by the same company.
