My '07 Accord 6 cyl with 30K miles has developed some dirty fuel injector symptoms. The dealer recommended he put in a gas additive called BG 44K. That stuff is many times more expensive that the additives you find in the auto supply store. I'd gladly have him put some BG 44K in if it really works-- but is it any better than STP/GumOut/Lucas/Chevron Techron, etc.?
What, specifically, are those symptoms? Honda (and the dealer ought to know this) prohibits the use of ANY additives or cleaners of ANY kind.
a quick Google scan shows a lot of positive comments for BG44K. seems Autozone carries it,and one post mentioned they have buy 1,get 1 free sales,perhaps with a coupon? -- Jim Yanik jyanik at localnet dot com
Slight engine roughness for a a minute or two after the first cold start in the morning, slightly rough idle after it warms up. Most driving is local/suburban. About once a month, I drive a 350 interstate trip and for a few days after that, the idle is fine.

They don't recommend anything, and they recommend that you don't use anything. But their dealers, being independent businesses, don't hesitate to say things that contradict what the manufacturer says. That all being said, I had great luck on an older Lexus by using Shell 93 for several tanks, to clean things out, then going back to Shell 87 to keep them clean. My gas mileage went up significantly.
it's also worth pointing out that honda are part of the "top tier gas" consortium that advocates higher detergent content of fuel to keep the engine running better. it's hard to see how a blanket "all additives are bad" statement can be reconciled with that.

Honda appears to have no problem with injector services and aftermarket fuel additives. Personal experience leads me to recommend Motorvac, which some garages offer. Techron, applied as per the label on the bottle, may suffice as a cheap alternative, but paying the $100 or so for a genuine Motorvac service is the best one can do.
In the past, the MSDS for BG 44K indicated that it included the same active ingredient as Techron. Later MSDS's for the same product indicated it was no longer included Techron. I wondered if the positive comments for BG44K were generated when it included Techron and now that it is pretty much the same as the stuff STP sells, it is less effective. I persoanlly like the Chevron Techron products, but if you are only going by persoanl; testimonials, it is difficult to say the Chevron prducts are better than others that claim to do the same thing. I know people who swear "Sea Foam" will fix almost any problem. To hear them talk, pouring it over the outside of the engine will restore the engine to new. I also know people who claim Split Fire Spark Plugs increae power by 25%, who claim K&N air filter improve fuel economy by 15%, who think teflon chunks in oil make engines lat forever, etc., etc., etc. I had a guy accost me at the gas pumps one day telling me how STP fuel system cleaner improved his fuel mile by 30%. I don' think BG44K will hurt your engine. So try it. Persoanlly, I'd try the Chevron Techron product first. I know the Techron product includes a useful active ingredient. Ed
IIRC, the hot recommendation on this NG a couple or more years ago was Chevron's Techron, which I've gone ahead with added more or less annually. My 2003 Accord sedan, I4, 5AT, etc., still runs great with 72,000 miles on the odometer. Whatever you decide to use, please post back and let us know the results, good or bad. TIA
OK, the consensus in my price range seems to be Chevron Techron so I bought a bottle of Concentrate Plus. The instructions say it treats up to 15 gallons. My tank currently is full so I'll need to wait a few days until I burn off a few gallons and then I'll dump the Techron in there. No doubt I'll have to jump back out of the way quickly to avoid being injured by the suddenly smooth running fire-breather my Accord will become again. Thanks for the input-- I'll let y'all know how it goes...
No, you can dump it in right now. But I think the best thing to do is to dump it into an empty tank and then immediately fill said tank. That will mix it well with the fresh gas.
