I have a 2021 Mazda CX5 that Scotty told me to buy. I've been keeping up with the scheduled maintenance, and now at 62k miles, I've been told I should do a fuel line service. Are these really necessary with this mileage, or is it another make money service that doesn't need to be done? I've had no trouble with the car at all.

Absolutely not. You're being hoodwinked. Where did you go ... the stealership?
@imperator The previous owner went there. I was still under warranty until the 60k mark, so I went to the dealer for oil and a warranty fix. They recommended it and a general internet search said maybe, so I came here for the straight info. I figured I probably didn't need it.
Modern detergent fuels do a pretty good job of keeping injectors clean for a long time. It's way too soon for yours. The bigger problem, however, is the direct injection technology the skyactive engines use. It makes engine valves very, very dirty and engines probably suffer a premature death because of it. The fuel line service you mentioned does nothing to mitigate this. It needs walnut shell blasting or something similar. The valves can be inspected fairly easily with a scope.
@imperator And how costly is that?
Depends where you are and the particular service that is being offered. You'll have to call your shop. I have no idea as I've never owned a direct injection engine (and hopefully never will).
