My roommate has a 06 Powerstroke and he was doing some research and found out that this new low-sulfer diesel that's showed up at all the pumps lately is hard on inner workings (at least on his 6.0). I've also heard this from my old man when he was researching the possibility of getting a diesel truck. He talked to some performance diesel folks down in S.C. and they told him the same thing about low-sulfer diesel fuel messing with diesels (at least the new ones). Something about the process that removes the sulfer also removes certain lubricating properties of diesel fuel that certain parts of our engines and/or fuel pumps rely on.

My question is: how does this affect my 1994 dodge 12V?? Should I be worried? Adding some sort of additive? I don't want to have to buy a new P-pump a few years down the road just because our wonderful EPA decided my truck wasn't efficiant enough already...

Thanks!

Search on here for the ULSD info.

Many of us are running 2 cycle oil to make up for the loss in lubricity. It is recommended to use 1 oz. per gallon or in my 97 I use 1 quart when I fill up. You can buy a gallon of the Wal-Mart 2 cycle TCW3 for $8.00. Make sure that it isnt synthetic and is ashless.
Do a search on here for 2 cycle also. There is alot to read.

 

i dont think it will have as much as an effect on 12 valves because they arent as fragile as a 6.0 power stroke

 

Old mechanics tales never die.
Oil companys and fed standards are not going to generade pumps.
A few years ago when sluphur was reduced the first time the same story made it's rounds. There was like no failures that were not already dying.
The ULSD has additive added for needed lube feature. Even if you got a shot of untreated(unlikey) it would be fine for one or two fillups from leftover treated fuel and no telling how much longer.
On the other hand, there may be problems getting the emission systems to accept various driving styles and operating conditions. Manufactures are working like crazy to alleviate the variations that showed up after engines were certified. It is my understanding many "engine check" lights are active and repairs are not prefected in eliminating condition.

 

There are a few guys around here that run ATF in their trucks. Makes sense. If you ever tear apart a tranny, look how clean everything is. Only downside is turning the fuel red. I guess you better have a locking fuel cap.

 

Ouch, a gallon of 2stroke oil for $8.00 each time you fill up? I just use Diesel Kleene (has that cetane booster), which comes in those 32 ounce bottles that'll treat about 4 tanks, and it only costs $6.00.

 

Most guys use a quart or 2 cycle per fill. I'm about to go back to running a little WMO per tank.

 

DOES ANYONE ACTUALLY READ THE POSTS ANYMORE?

1 quart per fillup.

I personally run 1 quart 2 cycle and the injection pump is quiter and I get about 1.5-2 mpg more versus not using it.

 

Back in the late 80's california went to a low sulfer fuel & the guys running N14's had a problem with leaking O rings in the fuel pumps & had to change to nitrile seals like those on the series 60's, this was only a problem for california fuel & older N14's.

 

I run Schaeffer's winter fuel additive and my 1 gallon container will treat 1000 gallons of fuel. It costs around $45 for a gallon.

 

throw in a gallon of used petrol oil for every tank... cummins says you can run up to 5% of used motor oil in the 12v's and 1 gal to 30 gal of fuel is only 3.33%. I just fill the empty rotella bottles with used oil and keep 1 in the truck for a fill up and heck its another gallon of fuel to burn for free.

 

I think maybe one point was overlooked. In-line injection pumps are lubed by engine oil, where a rotary type pump (VE or VP44) is lubed by fuel. ULSD should not affect the 12V engines with the P-pump. I haven't heard of any failures of P-pumps due to ULSD fuel either.

 

The ppump is lubed and cooled by fuel and oil.
