POWER SERVICE ADDAITVE ?

[George2615]

I just got a case of PS (white bottle). On the bottle it says to use 32oz for 100 gallon, 24oz - 75 gal., 16oz. - 50 gallon, 8oz. - 25 gallon. I can only guess that 12 1/2 gallon would use 4oz. so 6 1/4 gallon should only require 2oz. It won't hurt to put in a little extra. I usually mix in 4-5oz per 5 gallons which is double what is required.

Does it cause fuel dilution of the oil, damage the injectors, is it corrosive, what? Not disagreeing, just hoping for more info.

Your wear #'s will be off the scale big time by adding too much.

Your wear #'s will be off the scale big time by adding too much.

Which wear #s, and why? Again, I'm not disagreeing, I just want more info. For wear to increase it must either be diluting the oil or be highly corrosive and not burning inside the combustion chamber. The latter seems unlikely, so, guessing from minimal info, it sounds like it would be diluting the oil. Why? How would it be getting into the oil in the first place?

I have no financial relationship with PS, I just have a couple bottles of their product in my garage which were about to be added to diesel fuel, and I want to know if there's a reason I shouldn't be adding it in this winter.

I put either Gray/White bottle PS in the tractor fuel. A few years ago a bunch of water go in the fuel. What a mess but it only tooks a couple of hours to fix.

I have owned two diesel trucks since 1995 and neither has been given PS. Just figured the winterized fuel would work and since the truck uses up the fuel every two weeks it would be ok from gelling. While it does not get real cold down here for very long it does get in the teens every once in awhile. Never had a problem in the trucks with gelling.

Its supposed to be in the upper 70s here today so I don't think gelling will be an issue anytime soon. Momma Nature likes to average things out so I bet we are going to get real cold sometime this winter.

Since the tractor can sit for awhile on the same tank of fuel and my earlier water issue every 5 gallons of fuel gets PS. I man measure the same way Soundguy does, a careful couple of glugs.

The truck and tractor get UOA. The only wear item that is showing up on the tractor is silicon. Not at a high level just enough to be noticed. It could be a filter issue but I really don't operate in a dirt dusty environment and the filters are find. It could also be from sealents or gaskets.

There are only a couple UOAs on the tractor and I don't think the lab has seen many Yanmar engines. So there is not a big database on to draw averages. The next oil sample will be interesting.

Later,

Fuel additives will indeed show up in the oil from blowby, just like soot accumulates in diesel oil, as it too is from blowby.
The only wear metal I've ever seen from PowerService that is higher than normal is copper.
Something in the PS is believed to "leach" copper out of the bearing alloys. I've asked all over and no one can tell me if it is harmful- ie so my copper is a few PPMs high on my 7.3 Powerstroke. Does that mean the bearings will wear out in 500,000 miles when they would have gone 501,000 miles otherwise or is it a major issue
No one seems to know the definitive answer to the question of how much is too much if it is coming from leaching and not actual wear...remember oil can be leaching from all over the bearing material, not just the part the crank rides on...

 

[frank_miller]

Not all fuel adds will show up in UOA ie. Like Lucas will not, Fuel Power+ will not and some others.

I used PS and my copper, lead and some items where through the roof. I stopping using PS, as advise from oil testing people, and all went back to normal.

Your oil testing people, if you select a good company, will tell you if bad or not.

 

[Skyco]

I think ALL fuel additives will show up in oil, they just aren't testing for them The copper from PowerService isn't from the PowerService but is caused by it acting on the copper and lead. To be sure I'm clear the oil analysis labs are detecting the result of the additive not the additive itself
Like you I had high copper in my PSD and stopped using the PowerService for one oil change cycle, and it came down. I still use it but use less of it. The truck definitely runs better with it in there.....when I run out of what I have I'm going to start running a B2 mix instead- unless I have a spot problem where I need the PS.

Added later- here is an interesting read about oil analysis in general and a section about copper in particular-Wear Limits Vs. Trends

I should have worded that better. I ment it works like an octane booster.

Actually, no.

Octane boosters make the fuel burn slower, so there is less "ping" and pre-ignition.

Cetane boosters make the fuel burn faster, so the ignition is easier with cold temps.


The result of either when used correctly, is a better running engine. So in that regard it is correct.


Last winter nearly everyone was gelled up with the USLD fuel. -15F and it was lights out. PS didn't do diddly. Switched to Howes Diesel Treat and for winter use have to give it the nod.

For lubricity, I add 2 cycle oil at a dilution of 150:1 or so.



I think the ingredients in PS are mostly mineral spirits. Not good for lubricity!

In doing so, you've become an environmental criminal by the laws set by the EPA unless that 2 cycle oil is approved to be added to ULSD. Off to jail with you!

I think it is petroleum distillate, ie, #1 diesel fuel, aka kerosene.

In the eyes of EPA, we're ALL environmental criminals... I'm waiting for the potholes in my dirt road to be declared federally protected wetlands as "Waters of the United States." Then it will be fun seeing the county road crews get arrested by EPA.
