What fuel additive do you use?

[magothy1]

Just started running the Power Service the last few tanks. Took a trip up I-95 for Christmas, truck seems to be quieter at 70 mph and up, and also has a bit more pop if I accelerate to change lanes. Mileage seemed to be a touch better at those speeds, too. 'Course, if you spend money to try something new, you sure want to believe it helps, but the noise at those speeds is definately better. Used half a bottle, 16 oz I think, per fill up of 23 to 25 gallons.

'03 3500

Amsoil Additives

I use Amsoil Diesel Concentrate, Cetane Boost and when needed Cold Flow improver. Cetane Boost has improved fuel mileage.

16oz PS + 16oz 2-stroke oil

Power Service and Marvil Mystery oil cocktail is what I have used.

Could be, I don't know who makes it exactly. And while your thinking is not at all flawed with using what they recommend, they would not be able to deny you warranty for using another diesel fuel additive. The Federal Magnuson/Moss protects you there. Since a product, marketed as a diesel fuel additive is used, they cannot void warranty because you used another product properly for its intended purpose. However, the Magnuson/Moss act does not protect consumers who use a product for other than its marketed or intended purpose. The best example of this around these circles is guys who put 2 stroke gasoline mix oil in their diesel fuel. That product is intended for 2 stroke gasoline engines. It is not intended, by the manufacturer, for diesel use. Because of this "misuse" by definition, a manufacturer COULD rightly void warranty coverage for running 2 stroke oil, if they could determine that is what happened.



What's the point? Don't worry about using whatever diesel fuel additive works for you. I'm sure the stuff marketed by Fleetguard is fine. But I would caution guys who want to retain engine or fuel system warranty against using 2 stroke oil or some other product other than those intended and marketed as diesel fuel additives.

There is a October 2005 article in a magazine called Diesel Progress North American Edition that I just pulled up on the internet that says Fleetguard had just signed a blending agreement with a company caled Clean Diesel Technologies for the sale of Clean Diesels Platinum Plus Fuel-Borne Catalyst (FBC). To quote the article. " Fleetguard will purchase Platinum Plus FBC concentrate from Clean Diesel for blending into finished products for sale under the Fleet-tech brand to distributers and end users in the on-highway, off-road, marine and power generation sectors. "

Seems to answer the question as to who makes Fleet-tech's additive.

Good info. Thanks!

I could be wrong about this. I just checked out Clean Diesel Trechnologies website and also found an article in another magazine on the subject called Business Wire. The Platinum Plus product may be used for emisions reduction and control only and not a all around fuel additive. Anyone have any direct knowledge on who makes the Fleet-tech diesel additive?

I use 12 oz MMO, 8 oz PS, and a full pint of Stanadyne on every fill-up. It maybe overkill but I've seen a 2-3 MPG increase and better engine performance. I just don't trust the whole ULSD lubrication properties to let a fill-up go without additives.

 

[GBergen]

I voted Power Service. I actually use PS Grey and MMO. I have tried the 2-stroke oil but didn't note any difference in performance. Could be cause I'm only at 33k... . I'm still only seeing 16 MPG or so. . I use a 1 gallon plastic fuel can, add 96 oz of PS and a 32oz of MMO. Shaken not stirred. Then about . 5oz per gal when I add fuel. With prices where they are, I don't fill to the neck as often as I used to. I haven't seen Stanadyne in my area (could be I'm not looking hard enough ) and there is a Rocky Mountain Cummins dealer at the other end of the valley (30+ miles one way) so I haven't tried the Fleet tech yet.

Thanks for this thread, it's been enlightening.

Sense I have been using it before Oct, 2005, I wonder who actually makes it?? I should just get a hold of Fleetguard and ask I guess!

See what you can find out. Have you been using the Fleet-tech All Season Additive or the asphaltine conditioner? How well does it work?

 

[JEstes]

What about automatic transmission fluid? I've heard of guys using that alot too.

 

[Duluth Diesel]

Use anything but ATF. ATF has friction modifiers that can screw up your fuel system. Using ATF in diesel fuel is old school advice, from back when transmission fluid was just gear or hydraulic fluid. Old advice that doesn't apply to new ATF fluids and our fuel systems. Use at your own risk.

Ps/mmo

16 oz. Powerservice with 8 oz MMO.

 

[TMarszalek]

3 to 1 mix of Power Service to MMO, 1 ounce per gallon of fuel!

 

[JEstes]

Thanks Duluth Diesel! I didn't even think about the friction modifiers/detergents. I had just heard about alot of people using it.

 

[Soupy]

I use John Deere Fuel conditioner. It is always in stock and is suited for low sulphur fuels. They have a winter and summer blend. Used to use Howes but the JD stuff is easier to find and is probably a bit more money.

 

[Duluth Diesel]

Well the question comes down to "Who makes it for John Deere?"

See if the label says who makes it. Just curious.

 

[Soupy]

It simply says "Made for Deere and Company" Moline, Illinois. I have asked around however no one will say or perhaps they are not interested in knowing. All of the ULSD in this area is used for ag, on hwy, etc. There is no LSD anymore in this area. My JD dealer indicated that this conditioner is warranty approved (obviously) for their new tractors that will be using the new fuel . As such I have no reservations in using it in my '03 truck. It would be nice though to know who does make it. Their engine oil is refined by Imperial Oil (Esso) for Canadian market and I use that as well in my tractors and truck.

Guys,



FWIW, I just got off the phone with a friend of mine who works for Cummins. He had asked several of their engineers about the ULSD in an '03 truck. I know one of the engineers is in charge of handling Dodge specifically. Anyway, here's what they said:



Cummins has known that the ULSD has been coming for a long time. Therefore, they have made changes in pre-2007 engines since many of these will still be covered under the 100,000 mile warranty when the ULSD change occurs. The engineers said that they have done extensive testing on these engines and components. They said my '03 is fine. I would assume it would be the same on all pre-2007 3rd-gen trucks. My friend said they have also been testing older trucks aswell, but he didn't go into detail. He did mention one other interesting note. These engines use alot of the same parts as those sold in Europe, where ULSD has been mandatory for quite some time. Some of the engines are almost identical. Because of this, many of the parts were designed to work with ULSD in the first place.



The way I look at it, if Cummins is sure enough about this to stand behind a 100,000 mile warranty, they've probably done their homework.





Just thought I'd pass this along.
