Power service white or grey

[HOBrian]

I was at WM yesterday and saw that power service was in a grey and a white jug. What is the difference between the two of them and which would be the best to run in my truck 03 305/555. Thanks in advance for all info Oo.

The grey offers a greater amount of cetane additive.

 

[RobertP]

i run the grey in the warmer months and the white in the colder months due to the fact that the white has a anti gel addative in it.

 

[JGheen]

Yeah, they are basically the same except the white bottle supplement has an anti-gel in it and the grey bottle is supplement plus cetane booster.



Here's a question I have been wondering about... ... what happens if you mix too much of the stuff with one tank of fuel. I have not done this to the new truck but have always wondered the results, so for example, the bottle says 32oz. treats 100 gallons. Well, if one were to add an entire bottle to a 34 gallon tank instead of the typical 1/3 of a bottle per tank that I usually do, would this be detrimental to the engine? I am sure it would raise the cetane to a very high level but would this high level hurt anything?



Thanks, Joe

I put half a bottle (the big bottle) in less than 1/8th of a tank everytime I sledpull.



The engine is still alive.

SeaFoam?

How good is this SeaFoam with the ULSF?

Little help on the Cetane, ehh?

Yeah, It puts me right over the 500 mark!

I dumped the whole quart in one time. The engine sounded very quiet and really smooth until I refueled. Can't remember why I tried that little experiment but it did sound nice. Guess that's what all diesels would sound like if our fuel was 60 cetane.

I put the entire 32oz bottle into the tank every three months or so, been doing it like this for 43K miles. My engine runs absolutely flawless, can't say it has hurt anything.

I actually tried running the full bottle one time in my '98 12v and it did seem to run quieter and smoother now that i think about it. I never did it again after that thinking for some reason it was detrimental to my enigne so I have just been getting about 3 tanks per one 32 oz bottle. Good to hear others have not had any issues with running the entire bottle for one tank.

One time, on a long unloaded highway run, I pulled off to change fluids (mine, not the truck's). Although it had been running fine at speed, it was running rough at low speeds. I bough a grey quart bottle of PS. My next stop was about 50 miles down the road and was a planned fuel stop. There, I dumped in the whole bottle and filled up. The next time I pulled off, she was running smooth as silk.



That's when I quit using Howe's Meaner Power Cleaner. Apparently, it wasn't doing the job.



Lately I've been running 16 oz of PS and 16 oz of MMO per tank. Everything seems good, but I'm going to reduce the amout I'm using to save a few bucks.



This past summer I accidently filled my truck with gas (didn't start it, thank goodness). After siphoning the tank out, I added a full gallon of Howe's Diesel Treat (the only thing they had) in the hopes of offsetting any gas that was still in the tank. On that tank, my engine ran smoother and quieter than it ever has, before or since.

I just can't get away from a 50/50 mix of PS & 2 stroke injector oil. With ULSD the injector oil is probably as important as the PS.

I use 12 oz of PS and 4 oz of MM with every fill up of 20 to 30 gallons of fuel. I find a recycled 16 oz water bottle makes a good container to carry the additives. Seems to run smooth and hopefully will compensate for the low lube characteristic of the ultra low sulfur fuel. The white bottle of PS is used from Nov through March due to its the anti gel properties.

It is interesting that the grey bottle (cetane boost) would be nice to run with winter fuel, but the white bottle has the anti-gel in it? I might run the grey bottle and see how things go. I have never had a problem with gelling so the cetane boost will be nice... I hope Oo.

How 'bout 100% PowerService!!!

Well, I hate to admit my own foolishness, but here goes... On the way to work last week, and truck sputters... I knew fuel was low, but overhead still showed 40 miles. Anyway, truck died, and I coasted into a new fueling station, only to discover they didn't sell diesel, or even kerosene! I made several calls, and noone could bail me out.



All I had was my "mixture" of additive... 60 oz of PowerService and 36 oz of Marvel Mystery. Yeah, you guessed it. :-laf I poured the whole container in, primed the fuel system, and drove it reeeeal easy about 4 miles to the next station and filled up. The truck didn't smoke at all, and really didn't seem to run any different, although I drove real slow. Injectors should be squeaky clean to say the least!

They both have cetane booster don't they?



Whats the deal with cetane in a diesel anyway?



I know that adding an octane booster to a gas engine does nothing unless you have a high compression engine, like 12:1 or something, that would be prone to detonation on a lower octane fuel. But what does cetane do for a diesel engine?
