I was curious to see what would be the best fuel additive for my 12 valve. I want to keep her running strong and healthy and want to get the most out of her please let me know thanks!

 

hey dude, i use power service or lucas in mine

 

That stuff that looks kind of tannish right? And is in the clear bottle? I also have recently started using that

 

Define "best."

I use PowerService in my '03 but for the old 12-valves, I've heard nothing beats a couple ounces of automatic transmission fluid. A small bottle of 2-cycle oil is also supposed to keep em running happy. Unfortunately, my common rail injection pressures are way too high to use any kind of "heavy oils" like those without risking pump/injector damage, or I would be.

 

Hmmmmm thank you I never knew any of that would help whst exactly does it do???

 

Dieseldude, didn't you just have another thread recently about some issue with failed injectors?

 

Yep. Unfortunately, that was me. Still feeling the sting from that one.

At least in my case it wasn't totally unexpected. The 03-04 Common rail Dodges are kinda known to have injector issues. No one really really knows why. Some say it's the fact the injectors weren't engineered with ULSD in mind, while others say it's a lack of filtration.

Some people get lucky and don't have any trouble. Though my type of failure is documented by the Cummins Engineering team, mine failed in a different way than most go out. At least I got 102,000 miles out of 'em. Heard of some guys having to replace them at 60,000!

It's an old truck driver's trick. Supposedly it lubes the pump and injectors and changes the burn rate of the fuel for an increase in fuel mileage. There's a few threads on here about the use of 2-cycle oil and such as additives.

 

I've been running a 70/30 mix of WMO/2-stroke at a 60-to-1 treat rate in my '07 for almost two years/20k miles. I see no issues with running that type add in a commonrail. Engine runs smooth and quiet. I don't recommend Powerservice due to the largely solvent-like petroleum distillate nature of it. It ranks lower for lubricity properties than almost all other diesel fuel treatments. If I had to take a wild-assed guess as to what happened to your injectors I'd be considering the Powerservice.
