A dealership or lube franchise says I should get a “fuel injector flush” every 15,000 miles as maintenance. What do you think?
Don’t get me started! I have yet to see an owner’s manual that contains any such recommendation for ANY make of car! This service falls under the category of “additional profit,” perhaps to offset a “loss-leader” oil and filter change price. Your warranty does not require this service and no domestic or Asian vehicle manufacturer recommends it. 15-20 years ago when fuel injected vehicles were not common there were some problems with gasoline causing deposits in the fuel injectors, but those days are long gone. If you have a high mileage vehicle that is sluggish and all other causes have been ruled out, a couple cans of Techron additive in the gas tank won’t hurt and, in rare cases, may help. This product is available at most auto parts stores.
