What Fuel Treatment Do You Use?

[RadarRider]

Yes, this one's been asked a billion times, but after page 3 of trying to find a similar thread, I gave up. Anyhow, what fuel treatment do you use & why? Just out of curiosity. I've always used the Stanadyne(no, not because the Powerstroke Help guy does), but because a lot of companies I've worked for have used it in both turbo & non-turbo diesels & seems to work ok. It's somewhat reasonably priced, & they make it right next door in CT, so it doesn't take too long to get when I order it. I've also noticed I've gotten close to 2MPGs(about 1.88889 to be exact)extra. One thing is I don't trust some of the stuff they have @ AutoZone or NAPA 100%. Probably because I don't know too much about them. I would trust Lucas Oil because the last company I worked for used it & kept their F-550 pretty clean, & they've also used Howe's, but they've only used it in their drill rigs & hydraulic hammer power packs. I know there's gotta be something higher on the "diesel treatment food chain", so can people name some of what they use & give some exlpanation as to why they use it & what it did for them?

I like stanadyne performance formula in the winter time. Diesel Kleen by powerservice for the summer months.

I've used 2-stroke oil for the last 35-40K. Seemingly no problems with it. Quieted the engine down quite a bit, and gave me 2 mpg consistantly. Recently started getting a slight knock at idle in my 140 tune, so I have stopped using it to see if it makes a difference. I put a bottle of sea foam in the fuel bowl at last filter change, and started using diesel kleen, just to see if it helps. no results yet sorry.

stanadyne is an exellent product, especially for cleaning the fuel system. powerservice diesel kleen is an exellent product as well. it would be a tough battle as to which one is better, but imo the stanadyne is great for a once every two months shot for a good cleaning, and just run the diesel kleen in summer, and anti gel in the winter.

I used one bottle of Diesel Kleen on my last tank and today I put Lucas in it. Can't really say what it will do yet.

I run Diesel in my injectors... 750k and never an injector failure on three trucks... Just good filtered Diesel.

even after no lubricity from the ulsd? i have bus garages, and doh's buying seals and injectors by the dozens, they blame it on no lubricity in the new fuel
