I love the stuff for my old 2 strokes but I dont think I will be putting it in the d-max. It shouldnot have that much build up where I would need to.

I Used It Twice. The First Time I Drove 220 Miles Empty @ 60 Mph And 110 Miles Pulling A Steel Two Horse Trailer @ 65 Mph. I Hoped It Would Correct My Surging Idle, But It Didn't. On The Good Side It Did Average 19.37 Mpg. The Second Time I Put It In A Tank Full Of B100 Biodiesel On A Road Trip Empty But I Only Made 20.61 Mpg. Both Trips Where On Mostly 2 Lane Highway With Several Towns To Slow Down Thru. Like I Said It Didn't Help With The Surge. I Have A Couple Of Shell Stations That I Try To Use Because I Have Found Out That My Truck Doesn't Surge With Then. With Most Diesel It Does Surge. Dealer Said It Was The Fuel Pressure Regulator, But I Didn't Have The $1150.00 They Wanted To Replace It, So I Have Lived With It For The 20,000 Miles.

I steer clear of any alcohol based additives - but then, I run homebrewed biodiesel blends and it's better on the injectors and CP3 than anything else I've tried.

Let me clarify: I don't use alcohol based additives in my diesel. For my gas burner, it's okay.

I just used it in my DMAX and It has done very good. My mileage went up and feels like it doesn't lag as much. I just swapped my fuel filter and filled it up with Seafoam then installed it and bled the system.

I would not recommend using ANY additive with alcohol, Period. The alcohol can and will dry out your seals in your fuel system over time and defeats the purpose of lubricating the system. As for the added mileage, I would not be able to speak to that as I will not run it in my Maxes, but I will say that if you add alcohol to the combustion process you will probably see an increase in the efficiency of the fuel burn. I just would not add it through the fuel system as an additive. Injectors may not be a very big issue for non-LB7 owners, but believe me, if you run additives formulated with alcohol, they will become an issue before you expect them too. At the very least you will have added weeping of the fuel into the crank case as a result of dried out seals.

As does GM- I was told that when I had some problems with my 03 and was told by the service manager/head tech at my local garage NOT to use anything containing ALCOHOL in the Dmax, per GM. Have some people used these products, yes. I just know that since I was told direct and have to bring my truck in for work and they know that I have been told not to use it- I want that to be out of the question.

I would suggest using Howes additive. I runn it in 30 semis, 2 d-max's, 2 cummins', and a 6.5. From my experiance it helps power, fuel eco., and it helped surging in my 05 d-max. It also helps keep the injectors clean. There is regular Howes, which i use regularly, and theres a Howes Meaner Power Cleaner for more extreme conditions. The power cleaner is what stopped my surging.:gearjamin

Where did you Amsoil reps get the idea that Seafoam is alcohol based? It is 100% petroleum based. Do you know something no one else knows or just like spreading rumors?:mad:
