Took the girlfriend's car in for the free oil change over the weekend at the local Chevrolet dealer (she has a 2014 Malibu).
First thing they wanted to do was to sell her a "Lower Engine Cleaning Additive" for $59.95. They told me it was for cleaning the crud that builds up in the crankcase and should be done every 15K. Basically what they do is add an additive, high idle the engine for 15 minutes, then change the oil and filter. That sounds an awful like like an "engine flush".
I read the owner's manual for her car and GM states this:
Quote:
Engine Oil Additives/Engine Oil Flushes
Do not add anything to the oil. The recommended oils with the dexos specification and displaying the dexos certification mark are all that is needed for good performance and engine protection.
Engine oil system flushes are not recommended and could cause engine damage not covered by the vehicle warranty.
Hmm, so they want to do something that GM says specifically NOT TO DO!!!!!
They then tried to sell her an "Air-Fuel Induction Service" for $144.95. What they basically do is to clean the throttle body. Nowhere in the manual does it state that the throttle body needs periodic cleaning.
