Engine/Transmission (1994 - 1998) ultra-low sulfur

[KB0OU]

Yea, I am tired of playing GAmes anyway.

I ran a 18 wheeler to Anchorage and back for 5 years and have owned 7 diesels of my own, including the 18 wheeler. I rode submarines on every ocean and ran diesels on them too. I think I know a little about lubrication. I now make water for a living and have a degree in Civil Engieering. But hey, I am still trying to get it right and learning every day. I am a young 58 and looking for ward to simi retireing in about 7 years.



Original poster, Power Service is okay, but it is expensive for what you get.



See Ya,

Yes,i got my answer it seems ultra-low is ok. i work for a freightliner dealership & all new trucks have to run this fuel for a while now. i am inside all brands:cat,cummins,detroit,volvo,mercedes. the older mechanical fuel systems were easier to work on. anyone ever work on a kt600cummins?

fuel additive

from what i've read. Motor oil in the fuel will leave deposits in the engine, You don't know whats in drain oil. ULSD does not have enough lubricity for the P pump, I've seen pix. of the damage. I use power service in the white bottle year round

Why would the p pump need lubricity in the fuel when it is lubricated by engine oil. while I am not doubting you I think the damage you have seen is caused by things other than ULSD, such as water, grit from poor filtering, or poor engine oil change schedules. I don't use any additives and have not had any problems yet but than 223k is low mileage on these pumps and engines

... ... ... I've seen pix. of the damage.

I'd like to see them. Who published them (couldn't possibly be a manufacturer of additives could it?) and who determined that ULSD caused the damage?

Hello,

Engine oil does not lube everything in the P-7100 pump.

No way no how.

Correcto-mundo. Just like my ole pappy use to say. If it ain't broke, don't fix it. Some of these guys and gals must have some pretty fat pocketbooks. Being retired and on a fixed income it's hard just to pay for fuel period.

When the trucking company I drove for at the time of the switch to USLD began losing fuel system after fuel system (pump and injector problems), it was all I needed to see to know that USLD was very BAD for diesels that were not designed for it.

Since I have plenty of experience with Amsoil and Mobil 1 synthetic 2-stroke oil and the lubrication miracles it is capable of in extreme racing conditions, I have faith in it's ability to lube my P7100 pump even in very small quantities. It mixes extremely well, burns unbelievably clean, and leaves a very slippery surface behind; even after it's gone. It is not thick and heavy like 2-stroke oil was mistakenly described in an above post.

So there are 3 things I am positively convinced of:

1> USLD is BAD for my 12-valve Cummins
2> Amsoil synthetic Dominator 2-stroke oil is great stuff
3> Amsoil 2-stroke oil will always be FAR more consistent in quality and lubricity than ANY pump-diesel. I have filters and water separator to deal with fuel contaminants; but no way of knowing how good or bad any particular batch of diesel I buy is, or of dealing with low lubricity except to add my own. No filter or separator can help you with lubricity.

Much was made earlier about the questionable quality or benefits of additives when the real problem is the questionable and inconsistent quality of every tank of fuel you buy.
