fuel injector cleaners

With today's gasoline detergent additives, are fuel injector cleaners
(gumout, stp, etc.) needed? If so, how often should they be used?

 

i heard not to use gumout, it gets to hot and will burn the injectors. I
dont know which to recommend but supposable every oil change your suppose to
use fuel injector cleaner, but i am not positive on that.

In Canada, you can just use Mohawk Gasohol every now and then . . Seems
to keep my injectors clean, and cured a dripping one.

Best stuff I used is SeaFoam great! Do google on it.

In the USA, Shell (and probably Chevron) are good. I used to have a Nissan
300ZX that was very sensitive to gasoline detergency. I used cheapo stuff
until the idle got lumpy and the clutch got touchy, then would use a bottle
of fuel injector cleaner or a tank of Texaco (now owned by Shell), depending
on how much gas was in the tank when I decided to do something about it.
Either one would have the engine purring within about 100 miles. IMO the
tank of good gas worked as well as a bottle of the cleaner and was cheaper.

Mike,
I agree with you. I saw an ad. several months ago from Chevron. The ad.
said that they have the cleanest gasoline since they use the most
detergents. I realize that we can't believe everything we hear or see in
an advertisement but I have never had problems when I used Chevron gas and
other major brands of gasoline. Back to the original question:: When
should you use fuel injector cleaner? My answer--I'll tell you when I use
it--when I notice any problems related to fuel flow.

That works for me. Stumbling or surging or hard starting (because of the
fuel pump check valve not sealing well) are good reasons to try better gas
or fuel injector cleaner. Easy and cheap solutions for vague problems are a
good place to start.

I recall one gasoline brand used to invite customers to try it for five
tanks, but I think one tank of quality gasoline does as much good as five.

Mike,
Agreed. The only exception that I can think of is to use it whenever a
major tune-up is done. The local Honda dealership encourages its customers
to have a tune-up every 30,000 miles.
