Diesel Fuel Treatment Question

[RKassl]

Because of the Ultra Sulfur diesel fuel, I always have added Power Service to my Duramax year round. But I have noticed that the prices have skyrocketed and it looks like Howes Supplement is much cheaper. Do we have any users of Howes diesel treatment out there, any comments with long term use?


Thanks

I use Standine lubricity formula but I don’t think there is much difference in them. What you need is the lubricant in whatever you use. Your high pressure fuel pump works at up to 30,000 pounds or more and needs all the help it can get.

We us Lucus Diesel treatment for the last 6 years, you can hear the difference in the engine if you skip a tank. Without the treatment in the 65 gal tank we loose 2.4 miles per gallon when towing. IMHO use anyone of the fuel additives but do use something, your engine will operate better,

Power Service and Cummins have entered a marketing agreement together and Cummins is endorsing the Power Service products. Try your local Cummins parts counter for the Diesel Kleen. I’ve been paying 10.44 for the 80oz jugs for a few years now. Much cheaper than WM.
I also add Stanadyne Lubricity formula when I’m towing. It scores very well in the astm ball wear scar tests and neither of those products will harm anything if slightly overdosed so you don’t need to worry about precise measuring at the pump.

I’ve been impressed with lab results for Opti-lube XL Extreme. Opti-lube products are available from Amazon. The XL gallon provides lubricity improvement to 1280 gallons of fuel. Current cost is $67.17 gallon.

I've tried Power Service, Howe's, Lucas, Hot Shot, and Opti-Lube all just for grins. I will acknowledge any added lubricity for the high-pressure fuel pump can't be bad in any way. Tractor Supply, Atwoods, and sometimes Orscheln's beat Wally World prices hands down. For those that will mention improved milage, I'll just react with "you don't say?" because I, my neighbor, as well as our RV traveling companions might claim quieter operating engines, but no joy at the pump.

I tried different additive brands over 18 years of driving my Ford diesels. Couldn’t tell any difference in when using any one of them and not using any at all.

I gotta ask a dumb question. How come the diesel engine designers and manufacturers, and the petroleum refiners have not figured out that these engines need more lubricity for the high pressure fuel pump to operate more efficiently? I’m not disputing that additives may add good stuff for the engine…I just wonder. I used diesel kleen in my two previous Chevys just because. Haven’t used anything in this one yet.

Have never used an additive for diesel but regularly change fuel filters. I use injector cleaner one a year or so in gas engines.

I don’t think that is a dumb question. I am not aware of any manufacturer stating that you MUST use an additive to prevent injection system issues. To me that means these engines are designed to run on ULSD without additives. Do the additives provide some benefit? Ok. Necessary? No.

I don’t think they would manufacturer an engine that required additives. And even if they did, not without strict instructions to always use them.

I use fuel catalyst & Howes.

I have a 2017 F350 with 6.7 PowerStroke engine. It has the Bosch CP4 fuel pump that was designed for European formulated diesel which has lubricants missing from US diesel. There are many horror stories about this pump self destructing causing a $15,000 repair. Ram also used this pump, and has recalled these trucks to install the CP3 pump which doesn't have this issue. Ford hasn't issued a recall.

I used Archoil oil and fuel treatments in my old F250 6.0, and I use these products in my F350.

I believe that the modern common rail diesels probably do not need much if any additives. The refineries add lubricity to make up for the lack of sulfur in the fuel. I have a pair of older mechanical Cummins motors in my boat that I religiously treat with Diesel Kleen and Stanadyne because those motors were not designed to run on ulsd and boat motors are always “running uphill” in pushing the boat through water. The boat also has an “open to the atmosphere” fuel system that can get moisture from condensation in the tanks so I use Clear Diesel as well. I guess I personally feel that diesel kleen and a little Stanadyne when pulling won’t hurt the truck. Kind of like me eating and maintaining a well balanced diet and still taking my Centrum 50+ everyday.

I like that analogy! Makes complete sense.

These engines may not or probably don’t need a fuel additive but it’s really cheap insurance for a hard working fuel pump. A little extra lubricant can’t hurt.

The CP4 is the problem on the Fords. Its a disaster when it destructs itself and contaminates the entire fuel system. There is an aftermarket fuel pump being released soon to replace the CP4 pump without those issues. Ill wait a bit to see how that goes.

I use hotshot lubricity additive and Howes when I need antigel. Stanadyne is also good, I used it in my VW diesel for years in Wisconsin without gelling up.

They also make a "disaster prevention kit" that is supposed to protect things if the fuel pump self distructs.

I used Stanadyne performance formula and Lubricity formula in my 2001 Chevy 3500 dually for 20 years and its still running strong. I second the "gets better fuel mileage - you don't say", comment. It doesn't . Rural King also offers larger quantities at a reduced cost per use.

The process for refining to ultra low sulfur diesel takes the lubricity out of the fuel, probably not much the diesel manufacturer can do about that.

the cp4 replaced the cp3 because they wanted better fuel spray.Chevy quit using them in 2017 model because of failure. more pressure and less lube in pumps spelled eventual destruction. its not the engine design its the fuel delivery system use a lubricant
