Modern Car Fuel Injectors Could Be ADP Target | Agriculture




I have a 2019 Subaru Ascent that I really like. It has just under 22,000 miles.

My question is, at this mileage, do the injectors need to be cleaned, or for that matter, does anything have to be done to them? It runs well and gas mileage is good, but I am getting pressured by the dealership to have “fuel injector service” done for $ 300.

I had my last vehicle for 10 years and I have never touched the injectors. Call me curious.

You’re right to be curious, Rod. And resistant.

The short answer is no. Your fuel injectors should not need any type of maintenance at 22,000 miles. Neither should anything else on this engine. At 22,000 miles, unless there is a performance problem, oil changes should be sufficient. The car is brand new. And if there is something wrong with the fuel injectors at 22,000 miles, that should be covered by warranty, right?

I’m afraid your dealer is looking for what we call ADP – Additional Dealer Profit. So I would go on Google Maps, give him the route to the nearest lake, and suggest he go there and jump in.

Several decades ago, fuel injectors got dirty after a few tens of thousands of kilometers. And we had a big machine in the garage that we called the Wallet Vac. It was actually called the MotorVac.
