2023 Tahoe/oil additives

[SMITH2]

The dealership talked me into the oil additive in my 2023 Tahoe 6.2 engine and said to use every third oil change. Good idea or not???? This was my third change so I did. Should I continue???

No. Just use a quality synthetic. There just making $$ off you.

If you want some more in depth knowledge, this guy is VERY knowledgeable.

Here’s a pro tip if you can’t decide. If it’s not in the owners manual, and the dealer profits from the upsell it’s probably not necessary. If it really did anything they would provide a warranty or back it up somehow.

The dealership talked me into the oil additive ...

If you have no clue which specific oil additive -
THE oil additive? REALLY? -
then there's no way to know if the additive is helpful, harmless, useless, or bad for your engine.

To skip over a bunch of schidt, if you change your oil when the Oil Life Monitor says 25% instead of less,
and you change it with a high quality synthetic from Mobil1, Valvoline, Quaker State, or Pennzoil,
no motor oil additive should be necessary.
