Fuel Supplements

[Bob Beauchaine]

I thought that it might be beneficial to post information on Diesel Fuel Supplements. I do not recommend any one of these supplements over another. I have used two of the three and currently I am trying to find a source for the third.

Power Service (from their web site)

www.powerservice.com

Mfg. Benefits

Diesel Fuel Supplement (Winter)
>Prevents Gelling as low as -40 degrees.
>Lowers (CFPP) Cold Filter Plugging Points as much as 36 degrees keeps fuel filters from plugging with wax.
>Boosts Cetane up to 4 numbers for faster cold starts.
>Contains SlickDiesel lubricators for maximum fuel lubrication
>Protects pumps and injectors from accelerated wear

Diesel Kleen (Summer)
>Cleans dirty injectors and prevents injector sticking including HPCR systems.
>Boosts Cetane up to 6 numbers - engines run smother with less power lag and faster cold starts.
>Improves fuel economy up 8% - fuel savings exceed cost of additive.

Stanadyne Fuel Additive (from their web site)

www.stanadyne.com

Mfg. Benefits

Diesel Fuel Additive
>Improver performance and horse power.
>Cold weather protection.
>Lubricates, cleans and protects.
>Corrosion preventative.
>Exhaust After treatment safe.
>ULSD & B20 compatible.

Enertech Labs (From their web site)

www.enertechlabs.com

Complete Fuel Treatment
>Provides lubricity to meet or exceed all OEM specifications.
>Provides anti-gel protection - will lower CFFP and PP 25 to 35 degrees.
>Disperses water both dissolved and free water.
>Improves fuel injector cleanliness to meet or exceed Cummins N-14 specification.
>Raises Cetane 4 to 6 points.
>Disolves gum, Varnishes and carbon deposits and prevents new ones from forming.

I don't believe on using any fuel additives.

No fuel aditives might be fine if you dont pput many miles on or have it dealer serviced of which im shure they put it in and you dont know it , alot of fuel you buy has additives but usally not enough .

 

[Bob Beauchaine]

One point that needs to be remembered is that the ULSD now mandated by the government holds more water in suspension than previous blends. What can happen in colder areas is that this water can freeze out of suspension and clog fuel filters. Current supplements do not seem to handle this problem as well as they did previously. It has also been found that temps in the mid 40s up to the upper 50s are needed to bring it back into suspension.

Another problem for VE is that the pump is cooled by fuel. Fuel supplements also help to keep the fuel system cleaner thus extending the life of fuel system components from tank to injectors.

Here is some more information on ULSD problems:

There are also additional technical articles on the Enertec Labs web site if you are interested.

Fuel cold weather information

I was prompted to look into this problem by two posts on different web sites both of which had problems in cold temps. Both saw these problems correct when the ambient temp went above 45 degrees - it took over 48 hours for the suspended water to migrate back into the fuel.

I also found that there is no longer a winter blend because ULSD does not "play well" with the fuel used to "winterize No 1.

I use Amalgamated TDR WDA. They have a summer one as well and one, well two (summer and winter) for the newer common rail fuel systems. Have been using it for many years never a freeze or gel problem even as low as -29f.

I myself run the Stanadye performance additive and I can tell when ever I forget to put it in the tank, I drop 1 to 2 mpg.

 

[DVolk]

Howes and Lucas are good products as well but the lower priced diesel service works good too

 

[Bob Beauchaine]

I talked with a certified Bosch rebuild tech about 10 years ago and he told me that it was not uncommon to see 300,000 miles on VEs using Stanadyne Performance Formula. I have used both Stanadyne and Power Service with equal results. I have not tried Power Service Silver in the summer but will try it this year.

This is why I started this thread - to stir up input about additives.

There was a study about additives and their respective lubricity posted a few years ago. It was interesting that many of the additives actually reduced lubricity.
If I can find that article I will try to post it here.

Its kind of funny back in the early days all they used was ATF , now with all the new stuff ATF changed , Im un shure if Ford Type F changed or not . I know for the real old pumps its a good idea to use 2 stroke oil or 10 or 20 weight motor oil is almost mandated .

 

[Bob Beauchaine]

The last I heard Type F was not compatible with any other ATF. My old Red Line "Cheat Sheet" does not even show it let alone a cross reference for it. While it was a good product I personally would stay away from it and not use it as an lubricant in diesel fuel addative.

I have been using the Stanadyne Lubricity formula. It seems to be working fine. Ill let ya`ll know next month how it does on the mileage

When I went to go get parts for my pump at a certified Bosch repair shop They reccomended it to me... so we will see

ATF is a poor lubricant. I learned this while working with bearing engineers for much of my career. They didn't like applications using ATF because bearing life was reduced.
You are much better off with one of the additives that performed well in the study I attached, or with 2 cycle oil.

 

[RSchwarzli]

Yeah, I tend to run 2 stroke Shell at 100/1 in mine.
