the white bottle is the Diesel Klean, I'm not sure what the grey bottle is called. I personally have not seen any of the other products that they offer, just the diesel klean white & grey bottles...

 

Iv been using the Power Service in the white botle and have had good results from it.

 

My self the only colors I have seen for PSD is White, Gray and RED. The gray bottle is what I use in the summer as it gives a higher Cetane number to the fuel. The White is for winter as it gives anti-gel to the fuel but a lower Cetane number. The RED 911 is for an emergency when the fuel has gelled in the fuel filter and or tank.

FYI: Some parts houses charge a lot for PSD one of the cheapest places is Walmart so check prices before you buy as it can save you $4.00 or more per 96 oz jug.

 

right now wallyworld isnt selling the PSD in any form so your stuck getting it from whoever will sell it. I was able to pick up a bottle of the grey stuff for (gulp) $7 bux a quart. Being that I have some left in the garage, I wont hurt too bad [sm=boohoo.gif] while walmart gets restocked again...

 

That sucks as here in Iowa I can get a 96oz jug of white PS for $10.00 + tax at my local Mills Fleet Farm. Sad part is they do not sell the gray bottle PS so I too have to wait on wallys to restock

 

I used the mix for the first time yesterday, haven't driven much but I can definately tell a difference. I bought the grey bottle, it was around $18 I believe. I'm going to give it a whirl and if I get 1-3 mpg better then it has already payed for itself.

 

Isn't 16-20oz. to a tank full a bit much? According to the PSD manufacturer the ratio should be 1:400 which comes out to about 8-10oz. per fill up. That is what I use in my truck and I fill up at 1/4 tank which takes about 26 gallons (26*128)/8=1:416. I noticed after running a few tanks (6 or more) at the 16-20oz. level, it started not running good. The next fillup, I did not put any additive in and it ran good again. And running 8-10oz. has not resulted in the problems.
So, I run 8-10oz. of PSD with 8 oz. of MMO.

 

this is where personal findings come into effect. I started with only 8oz and noticed a fuel mileage increase, went to 16 oz and got 2x the mileage increase, when I tried 24oz just for giggles I didnt have any extra increase. but the MMO did help some and I found 16oz PS and 8 MMO is my personal sweet spot
