Do you guys use any fuel additive on your trucks? I used Opti-lube XPD on my Duramax before and everyone on the Duramax forums swore by it. Being new to Ford, I am interested in what you all do.

 

I like to use the Ford PM22 cetane booster. It may add a bit more lubricity to the ULSD we have to use now. However, the Ford manual clearly states no additives are necessary.

 

Opti-Lube XPD or Archoil 6200.

 

I use power service have in my 2014 and 2015.no issues.

 

The infamous diesel fuel additive study:

i also ran ran this until I figured out it was costing me at least 1 to 1.5 mpgs. Strange because the whole reason I bought it was for increasing mpgs. Did the same thing on my old 2014 6.7. Maybe our cetane was already at optimal levels.

 

How could it cost you mpg?

 

I don't have a clue. Ran it for 3 tanks and driving the exact same speed and route my mpg went down by 1.5. Stopped using it and mpg went back up. Repeated test on different vehicle. Same result. I know cetane affects the combustion rating of the diesel and being more combustible past a certain point must reduce efficiency. Just guessing though.

 

I add Power Service Diesel Kleen to my '08 6.4L and it increases MPG by about 1. The engine also idles smoother and quieter as well, and seems to have just a bit more pep.

 

Interesting. I've run with it and without, never noticed any mpg changes. Cetane rating should be listed on the pump, much like Octane. Ford claims the minimum cetane for all powerstrokes is 45. The pumps in my town are labeled 40. However, the Ford lit stating as much is from 2008. I'm pretty sure I've seen the 6.7L minimum is 40...but it doesn't appear to be in the owners manual.

Used Power Service in my Cummins..... Quieted it down and smoothed it right out. Now in my 2017 I started using pm22. I don't see any difference when using it so far anyway.

 

Opti lube Sumer formula, can be mixed 2,560:1 and works. Fuel is treated already for winter conditions so no need to add anything as anti gel

 

What is the reasoning for not having the additives right from the pump? How many people add to gasses?

 

I run Sta-Bil in all my off-road equipment... Generator, ATV, Chainsaw etc. Chevron's Teckron gets used once a year in auto and Off-Road equipment too. Other than than... not much.

 

Cetane percentage is not listed on the pumps around here.

As far as additives, I have run Stanadyne, Optilube, Archoil and Power Service in my 6.7's. None showed any fuel economy increase over the other. This may be because cetane level is higher in parts of Texas (48 minimum in 110 counties)
