2023 Tahoe Fuel Induction, Injection, Throttle Body and Ethanol Service

[dmba]

2023 Tahoe LT @ 51K Miles

Dealer recommended Fuel Induction Service, Injection, Throttle Body and Ethanol Treatment at $415. Don’t know much but reading through the forum, it seems it can be done by myself with Techron cleaner?

Transmission Service to be completed this week too.

Profit center for the dealer.

Probably BG Fuel Induction Service Kit and BG Ethanol Fuel System Defender & Drier.

Money better spent on a catch can and add Techron Complete Fuel System Cleaner every 3-4k miles to the fuel tank at fill up in the correct concentration.

You could peek at the throttle body, I have no history on the DI engines and how dirty the throttle bodies get, but on my 2005 port injected Denali with 275,000 miles, I may have cleaned the throttle body once just as a preventative while I had the intake body off.
