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
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.
Well, Honda doesn't necessarily PROHIBIT anything, in that they're going
to come arrest you or something if you put it in.
They don't recommend anything, and they recommend that you don't use
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.
After digging into my records, I see I made a slight mistake: the
prohibition is for the AUTO TRANSMISSION.
Honda appears to have no problem with injector services and aftermarket
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
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
Thanks for the input-- I'll let y'all know how it goes...
