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???

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.

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.

My Dealer did a "major" 20k service yesterday on our Denali. I asked for Mobil 1 and they also added the oil additive. I am seriously considering buying the extended warranty. It gets me 6 years or to 60k miles from when I buy it for $3,100.00. Right now I am at 3 years and 20k miles. To extend the warranty to the 5 year 60k powertrain coverage is $2,100.00.

If I could talk 'em down to $2,875 for the 6 yr 60k warranty I'd consider it,
'cause it's likely you'll spend $2,875 fixing its various sundry issues over the next 6 years.

Yea, I just got an email from GM offering several levels of an extended warranty. Prices are all higher that what the Dealer is offering from some in-state outfit. The GM 5 yr 60k is $5k.

Check Knapp or James Black Cadillac and see what their pricing would be.

I wouldn't do any oil additives. My dealership tried to push those on me and I discovered the owners of the dealership also had a financial stake in the oil additive company.
