ah, looked at spec sheet:

5.25 Oz. / 155 Ml treats approximately 20 gallons gasoline or diesel
32 Oz. (1 quart) / 946 Ml treats 100 gallons gasoline or diesel
128 Oz. (1 gallon) / 3785 Ml treats 400 gallons gasoline or diesel


so 8oz for a CTD/34 gallons, sound right?

That MSDS looks like a shortened version of the one for Dirt.

 

During the Lucas portion of the test I dumped in a 5.25 oz container at every fill up. Generally I pump in 25-28 gallons.

 

I think the additives are a waste of money.There has never been any hard evidence of MPG gains. Rock did a nice job,but his data proves nothing,however if you think it helps, then why not use them,who knows??

 

hamma, i think Rock's data is as good as any.

anything you see scientific or commercial is slanted or "mean" vice "average" or some such. i track mine in an Excel spreadsheet, and i can tell stuff like that by mine.

like how fast my kid drove when she took it on vacation

what about ATF? saw some guy put that in, in one post?
put motor oil in my tank last nite, can't find additives locally

 

I don't run additives for mileage increase but for added lubrication for the injection system and to keep the injector tips clean. Our diesel fuel is crappy at best.

Does any hard data exist that suggest the failure to use fuel additives will cause pre-mature pump failure.?? what does DC and cummins say about additives??

 

Cummins states that a fuel additive shouldn't be needed for commercially obtained fuel, but they also state that when an additive is used one should verify that it's performing as advertised, and that they won't be liable for damage caused by an additive that isn't sold by Cummins. A fair number of owners in Canada experienced pump failures, evidently it's a local fuel problem, but when I asked in one of the threads if anyone who had a failure had been using a fuel additive no one replied.

As low sulfur diesel fuel continues to be sold in the United States without any requirement for lubricity, there continues to exist the potential for wear problems especially in engines with the rotary distributor fuel injection pumps. The consumer is led to believe that all is well as fuel producers would not market a “low lubricity or lubricity deficient” fuel that could promote wear. That however may or may not be the case since there is “no measuring stick” presently being used. Without the enforcement of a lubricity standard, neither consumers nor fuel distributors can be certain as to whether the fuel has adequate lubricity.

As soon as the industry standard for diesel fuel D975 incorporates a lubricity standard, the potential for wear problems will become a distant memory. This standard will most certainly be needed prior to the next planned reduction of sulfur in 2006.

 

Mr. Hammajamma.

You may want to try to get ahold of Mr. Scott Gerrard of J&S Diesel in Las Vegas, NV., the local Bosch dealer and repair facility. He has first hand information regarding what is going on with our fuel injection systems and the damage that is being done to them by the fuels that are available to us.

I've been to a number of seminars he has given and if he is only halfway right about the quality of the fuel we are using, especially in certain parts of the country, then the use of some sort of an additive that increases lubricity may be something you may want to consider for your truck engine.

I don't recall seeing anyone trying to sell any of us an additive, in this thread. I believe we're just trying to help one another try to preserve our trucks, as much as possible.

There are a number of other threads on this site that are addressing the fuel additive issues, also. If you haven't already, you may want to read them, also. I posted some of what Mr. Gerrard had to say, on one of them (post by Buffalo).

I hope these suggestions help get you the information you are looking for.
