Fuel Injection Cleaning - - Waste?

[Tommo]

I'm taking my OBS in for it's 60k maintenance service and I know the dealer
will be suggesting that I spend $120.00 (with coupon) to clean my fuel
injectors. Am I wrong to balk at that service? Won't a $5 additive that I
buy at the store do the same thing?

Please enlighten me.

I use Techtron by Chevron. Works great just add it to a tank of gas. Jeff

Techron once or twice a year, Chevron
gas at least every other tank. I've
never had any problems.

I've been using Techron Fuel System cleaner for about 15 years and
never had to do a dealer/service cleaning. Most of my cars were driven
to 150,000 + miles. I use the"TECHRON FUEL SYSTEM CLEANER" which is
the more concentrated over the INJECTOR version. Wal-Mart for about 6
dollars every 10,000 miles or so. In addition I use major brand gas
always.

Hi,

Limited experience here of all my previous cars vs the one I most
recently acquired: I've never had fuel injectors "serviced" or "cleaned"
on mine, the newest addition (Toyota Camry, not a Subie) had it done
regularly by the dealer. As far as I can tell comparing within my small
sample, injector cleaning doesn't hurt, except maybe the pocketbook.
Whether it helps is arguable.

I currently use Berryman's B-12 (available at Wally World and all major
auto parts chains) in both my Subie and the Toyota and have used Techron
in Subie in the past. I can't tell any real difference between the
performance of the two products, though Techron's about twice the price
of B-12.

Are you sure that's not "Techron Concentrate"? The other Chevron
products containing "Techron" are marketed as "Pro-Gard".

I don't know about the Berryman product, but I know what Chevron
uses. It's a concentrated form of what they already add to their
gas (polyether amines) and not some mystery fuel additive. Chevron
claims that the stuff in their gas isn't a "dilution" but that the
individua formulations are designed for different purposes.

I don't know if they still have this warning, but Chevron used to
warn that their Techron Concentrate might not be suitable for more
than one use per oil change because the high concentration might
cause accelerated depletion of the oil additive package. They also
recommended that it be done just before an oil change.

Unless you specifically suspect the injectors are dirty, then stay away
from the service. As long as you don't introduce contaminants into the
system by running no-name gas, running until empty, or sugar in your gas
tank, it should stay clean for quite a long time. I have never had the
service performed and other parts of the car fail long before any
injector problems were experienced.

I'm with Rick on the use of Berryman's B-12. Been using it for yrs on
anything that is related to cleaning fuel systems. Old engines with
carbs, you can spray directly on and down the carb and see the crud
washed away. I try and put one can in a tank of fuel once a yr for PM
and have never had any problems. I typ keep my vehicles at least 10
yrs and/or 200k miles. My 30 yr old garden tractor usually gets a
couple oz. in the tank once a yr and never had a carb problem.
