Worth it?
If so, who to use?
Witch Hunter was good to me and let me know I sent a bad set of injectors that should not be serviced. I'd say it's not a bad idea once per decade or so or if the injectors sat for a while.
I picked up a rebuild set for my injectors at http://www.mrinjectorparts.com. He offers cleaning services as well, but I have not used them. Customer service was perfect. He was able to answer any questions I had and his turnaround time was short.
I just use Chevron Techron before I change the oil and always buy quality fuel. Never have a problem.
I think the EvoD guys will do it for you (well they offer it as a service for Evos for sure). It's important if you use E85 to clean them periodically. For race applications, I'd want to have them both cleaned and flow checked to verify that they're flowing correctly still. In that case you might contact your injector manufacturer to see who they recommend (assuming you're not using OEM injectors).
You probably can't feel the reduction in power from reduced atomization due to stuff caught at the nozzle/pintle.Quote:

I've not seen it in my non-E85 tuned vehicles, but there's enough anecdotal evidence around mowers, boats and other small engines that leads me to believe that ethanol corrosion/gunkiness is a real issue.
Oh wow.
Read an article in the SCCA magazine 9 months or a year ago, they recommended GumOut. Of course they had a full page add in the magazine.
Gum Out is a major SCCA sponsor. That does not mean the product doesn't work, but just sayin.
lol @ people thinking that dumping Gum Out in the tank is the same as back-flowing injectors with super-chem solvent and replacing tired parts.
I use Berryman's B-12 Chemtool every once in a while and it's made a noticeable improvement in my Miata. I would still say getting them cleaned/rebuilt by someone like this (http://witchhunter.com/) is the best route and the only real way to get them in proper working order. I'd still recommend the occasional fuel treatment though to get rid of moisture and that "goop" pictured above. Never noticed anything remotely that bad on any of my vehicles before though. I've had clogged and failed injectors, but they still looked okay externally.
Gum out is a sponsor, but I can say that the free samples of stuff I got from them at Nationals fixed up my mower and edger lickity split. Several guys in the know Including AH felt it was a good product, as well as their AT conditioning stuff.
I've always felt that a little injector treatment periodically over the life of a car was the best way to prevent these really nasty stuff. techron is very good.
I've Used rc engineering & miatacage. 100 bucks for blueprinted set with exchange. Someone told me injector rx in Houston was good.
I had to spend 400. to fix an issue with my mower last year from ethanol holding the needle seats open in my carb and flooding the engine with gas which pushed the oil out of ever place it could come out.
I also had to have the carb cleaned twice on my echo chainsaw for the same reason.
I was told to use Stabil in all the gas in these two machines and super unleaded and havent had a problem since.
I was also told that the higher the grade the less the ethanol.
But I can attest to the fact that it does jack up your small engines.
Sounds like a country song. Throw in a runaway wife and you might have a hit. ;)Quote:

I tease him about his ethanol removing still.
Its not hard.
I need to, its sure screwed up my lawn tractor.
thats my country song, and i'm sticking to it!
Does he jar the ethanol for consumption later? ;-)
Between the inspection problems and the ethanol in gasoline stories you guys are talking about, I'm glad I live in Cooke County. No smog inspections and two stations in town with straight, alcohol free, gasoline.
You own a mower worth more than $400?Quote:

My plan is to buy less mower and more tires.
The grasshopper wants to know how do that? Run it through your moonshine distiller?Quote:
