Fuel Injection Cleaning - - Waste?

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.

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.
