It's mostly a profit center for the dealership. Echlin hooked up directly to the fuel rail does clean injectors very well though and can help those engines that are fed a steady diet of low quality fuel. Chevron's Techron in the little bottles is also very good at cleaning the injectors.My Dealer says I’m due for fuel injection service @ 30,000 mi. We never discussed price or what they do. Is this necessary? 5.3 engine.
