I called the refineries to ask if it was true or not this is what they said.. They said it is refined out to 15ppm but they also said they add additive before leaves the refinery. the reason I checked is because a farmer buddy who buys about 10000 gallons a month and that is what he said they told him. So this is why checked up on it. Tell me what you think?

 

I've heard alot of things but has got to take it all. Why would they put a luburcant in when they took one out. Dosn't make any sense.

 

Why Not???????? I think that they realized the issues that were going to happen if they did not add the additives. Better be safe then sorry though! I would still add a lubricant to my fuel!----------The new ULSD that Ihave been running gets on the average 1.4mpg different that the regular LSD!

 

buddy of mine is having the pump rebuilt on his old 92 jetta that mysteriously started to leak about 2 weeks ago.the pump guy says they have been getting in way to many pumps lately,and run an additive for lubrication.

 

The sulphur reduction process necessary to refine ULSD also removes some of the aromatics and their lubricative qualities. Additives are reportedly blended in post-refinery and prior to your fuel tank, but I use silver PS just to make sure. Even with LSD, it kept my injectors cleaner and helped a tad on the mileage.

 

XLR8R is correct about the lubricating aromatics. The refiners are adding lubricants, but like anything manufactured, there is a learning curve concerning the least expensive way to get proper additives for lubrication. Don't kid yourselves, they make the fuel as inexpensive as they can to meet the fuel regulations and until it becomes more familiar to them, an additive is just good insurance.

 

By law all diesel fuel must meet a certain lubricity. Besides abiding by the law refiners know that if lube isn't added back lots of engines will die, not real good for repeat business.

Not surprised the '92 Jetta is having problems. Engines built before 1994 often have rubber materials that are incompatible with USLD or bio.

 

I wouldn't worry about it. Cenex is my refiner and I haven't had any problems.

 

Cenex is one of the few refinery I would consider trusting to do it right. Around here, you have no idea who the refinery is.
I'm not as trusting as Bill, or don't have as good a local dealer: I think cost out weighs service and they are adding just enough of the cheapest stuff they can get!
I'll add my own to be sure something decent is in there... at least till the dust settles and the results are in on the side effects of ULSD.

I agree - what can it hurt to add some more of the good stuff?

 

Ok, I'm new to the CTD scene, what is "silver PS"? I know it is an additive that lubricates, but what brand?
Thanks in advance,

Power Service in the silver bottle or jug - manufactured by Diesel Kleen and found at Walmarts everywhere.

 

Thanks XLR8R! We have many Walmarts here...

Anytime...

 

The silver PS doesn't provide winter anti-gel protection whereas the white jug does.
