fuel system additives

Is there a necessity for those fuel injector cleaner/system cleaner
additives? I know they have cleaners in gas, but I usually put one
bottle in at each oil change, full tank. Is it worth the extra cost
to do this? Does it make a difference?

 

What have you found the results to be over the period of time that you
have been using the additives?

Do you believe that your vehicle has performed better?

Have you spent less money on fuel?

 

yes, that's why it's mandated by federal law.

there is a federal minimum. but different brands vary from that, in
some cases up to five times the minimum.

if you're having injector problems, yes. if you buy cheap gas, most
definitely. once every 3 months or so is fine.

 

A direct quote from Honda's internal dealer website:
.. Fuel injection (induction) cleaning/flushing is not recommended by
American
Honda. This is an unnecessary maintenance procedure and an improper repair
procedure. If a Honda vehicle is experiencing a fuel injector malfunction,
the
faulty injector should be replaced.
Injector O-ring and seal damage can occur.

 

the after-market cleaning/flushing sold by monkey-lube outfits /is/
unnecessary and it /can/ cause problems just like they say. but adding
detergent to your gas sufficient to clean injectors, as is frequently
cited here when people have "flooded" start problems, is a good idea and
it doesn't harm o-rings or seals.

 

Nothing but 'snake oil'. As far as I know there are no auto
manufacturers who recommend or suggest their use.

 

but additives are vital. the car manufacturers that "don't recommend or
suggest their use" /do/ however seem very anxious to ensure that crappy
gas that gums up fuel lines, leaves deposits in injectors, fouls intake
valves and carbons up the combustion chamber is not misinterpreted as
being /their/ fault.

Hi,
Be careful, you may destroy catalytic converter.

 

wow, what is this thread??? an urban legend competition?

 

I use STP gas treatment. I maybe get another mile or twoper gallon
out of that tank, so the cost is a wash. I also heard once a few
years back that if you floor your vehicle it will "blast" the
injectors clean. Is this true or myth as well?

For some reason, the 'Top Tier' labels on the Shell gas pumps have
disappeared in this area (south of Chicago). I don't know if this means
that Shell dropped the program, or just in this area, or they just don't
want to keep answering 'what's that sticker on the pump' questions.

 

myth. injectors are constant pressure. all max injection does is make
them open for longer, and that's not going to clear anything multiple
short injections won't do.
