    Independent shop recommended it as: “Performing a fuel induction service every 30,000 miles is important because it cleans carbon buildup from the fuel system, improving engine performance, fuel efficiency, and reducing emissions.”

    I purchased a 2006 Prius at 122000 miles, doing the standard maintenance at 125000. When I do my own oil changes, I always use a bottle of Techron in the next fueling. The last “Fuel system cleaned/serviced” on record from previous owner was 12/17/2019 at 97,671 mi.

    Sorry; either you misunderstood or someone is feeding you BS. There is NO carbon build-up in your fuel delivery system ONLY on the injector tips in and around the combustion chamber. IMHO, your Techcron treatments is enough. There are plenty of people well pass 200K miles that have NEVER done anything to their fuel delivery system - NO additives at all; just whatever mixed in with the gas station's blend.
    I'd be more inclined to change out fluids not mentioned in the OEM manual (ie. brake fluid and ATF). They've gone almost 20 years and over 100K miles, so probably prudent to change with a fresh batch.

    Just my two cents....

    Get some rags and some carb cleaner and stuff them down the throttle body and you will have cleaned up the oil that builds up in the intake manifold and varnish that builds up in the throttle body. That's equivalent, maybe even better than an induction cleaning.
