fuel additives
 

for an 04? I have been using marvels mystery oil in a 99 powersoak, but dont know if I need to run any fuel additive for an 04 cummins or not. If so, what do you guys suggest.

Thanks

stanadyne,
recommended by my local dodge dealership

schaeffee oil,
recommended by my local over the road truck repair shop, shop forman said this stuff helps lube the fuel injectors as the government has taken lube out of the fuel, he had trucks in for regular service with
600K+ miles.

both products seem to work fine, no fuel related problems (2005 model), with my truck and it gets good fuel mpg.

Have used Lucas with good results and I like the fact iIcan use it in the wife's gas engine, but if you need anti gel for the winter then Howes or Power Service in the white jug.

Fuel Additives
 

I use about 8oz's of Diesel Kleen in every tank of my 2000 Ram. I runs a little quieter and I get 1 mile per gallon increase in fuel mileage consistently. I didn't believe it and stopped and started using several times and each time gained the extra mile per gallon. As stated on the bottle, the benefit is worth more than the cost of the additive.

It also comes in a winter anti gel blend if you need it

You may want to add some lub to the fuel.

The ULSD has had the lubricants removed when the sulphur is removed. The lub is supposed to be added back, but is it or enough to lub the injectors?

I started adding 2/3 oz of 2 stroke oil to my fuel in '06 when the ULSD first hit the market and am still adding the same amount. There are better lubs available but may not be as easily obtained. 10% bio diesel is the best if you can get it.

The 2 stroke oil to use needs to be TCW-3 ashless. I get the gallon jug at Wally world. I keep four 16oz bottles under the rear seat to use and refill from the gallon jug.

Be carfull with useing some additives, if it contains alcohol or a solvent do not use it. A sticking injector can sometimes be cleared up with the solvent additives but should only be used when needed.

I understand that Marvel Mystery oil is not good for the CR engines.

That is true. They do offer a anti gel diesel additive that is also a fuel treatment.

Diesel Kleen....

Diesel Kleen in the gray bottle. Had a very rough idle on start up when I first bought this truck with 22k miles on the clock. The dealer replaced two injectors and a harness but occasionally it still idled very rough after starting it up. After about 30 seconds it leveled out and ran good.

Tried a bottle of diesel kleen simply because Wally World carries it and I know they don't stock merchandise that does not move. It corrected my problem immediately!!!! On the initial dose I used the recommeded strength and then use about 6 oz per fill up since then. After over two years I have not had one single event of rough idle.

I also run TC-W3, about 16oz per tank. Every third of fourth tank I add 8oz of Power Service Diesel Kleen.

Don't need it. Just buy good quality fuel at a place that moves alot.

Finally found the chart...this was a study conducted by Arlen Spicer and published in depth at Diesel Place.com. If you're interested in the entire .pdf PM your e-mail and I'll send a copy.

I've used the Opti-Lube XPD, and it smoothed the engine out quite a bit, but I got no mileage gains and it was so inconvenient to purchase (shipping to AK bites) that I've not bothered to use it anymore. For day-to-day I use the Power Services gray bottle in the summer and the white bottle in the winter. Never had a gel or water issue, and when you're going from a heated garage to subzero temps every day, that's more difficult than many realize.

I developed injector problems @ 80K - rough idle. Local diesel shop recommended, and I did, 5-gal of his high spec bio-fuel and two bottles of redline diesel fuel catalyst... that was two years ago and have not had a problem since. I'm now at 103K, and I continue to use redline and PS mix with every fillup. Engine runs more quiet and smooth - and there is about 1-mpg increase.

There was a study done that was posted in 2007 on The Diesel Place. Just found the link.

The Two Stroke oil was way up there and Lucas was way down there.

I have been running Amsoil diesel concentrate with good results. seems to be getting 1-2 mpg better and overall smoother feel to it as well. I noticed they have anti-gel, cetane boost, and cleaners as well when i was on their site.
