Will the new ultra low sulfer fuel go over well in my '99?

 

Run some sort of diesel additive like diesel kleen. Since the ULSD has less lubricity than the LSD in it. The ULSD has been out for a while, you probably have pumped it before without knowing it, unless you go to the same station all the time. No, your truck wont just explode if you dont use an additive but its a good idea since the thought of less lubricity is not good. Supposedly they add something to bring it back, but I don't trust the fuel stations.

 

It should be fine. Remember, only the raw ULSD is not recommended. I wouldn't recommend wasting money with the snake oils (aka additives). Currently no real proof that they extend the life of your motor significantly. In fact, no real proof that they even pay for themselves. OTOH, if you were selling the stuff, you would say it cures the common cold and herpes in 2 weeks of use.

By law, at terminal level, they have to add some additives already to bring it up to spec. I think of it like food. If 1 plate fills you up, think 3 plates will do more?

 

I have run it in my truck b-4. I noticed a couple of o-ring replacements on my fuel bowl. I found a station that was still selling LSD, so i have been lucky till now. They just switched the pump to ULSD. I guess i will find out how much less lubrication there is.

 

Thanks guys. Just wondering because the station near me has ultra low sulfer and its cheaper than everyone else.

 

The only issue I see with ULSD is that it can leach out the sulfur from the rings. That, no additive without sulfur in it can help.

 

Huh.......I've seen the ULSD blamed for a lot of things but that's the 1st time for that.

 

It does cause the seals to shrink and harden and thus cause it to leak.

 

Ah, so you meant o-rings.

 

Yes I did. I tend to call them "c**k rings" and I remembered that I should not refer to them in that way on the site so I erased the word and forgot to put the "o" back in it.

 

It will work fine. But B5 biodiesel will work even better. So will some 2-stroke oil.

 

How better? Certainly not in the mileage and power department.

Will that do something with the injectors?

 

Better lubrication. It is also said to quiet down the motor quite a bit, do to lubrication. It may extend the life of injectors.

I get B5 for the same price as non-biodiesel....so its a no-brainer for me.

I've also be running B50 in my boat...and the engine runs much quieter and smoother. No problems at all with a 1977 marine engine and fuel system (been running biodiesel since ULSD came to the pump).

 

Look at the Regulated Return. It quietened the motor too. #8 was running in a different condition than the rest. As such, the combustion characteristics were different and caused the noise. B5 does the same thing. It changes the way the explosion in the cylinders take place. That changes the sound. The little bit of lubrication difference will not change the sound. I doubt you can hear the difference without expensive and sophisticated filtering equipment and software.

That part is speculation. I haven't seen anything that proves that bio can make a difference in the life of the injectors.

If you can, it might be ok since they get about the same mileage and power.

 

Since Sept. 2007 we have ran 20,000 gallons of ULSD through the engines below, we never use additives. Some of the engines are as old as 1992 and have not had any issues.
