How to stop dealership service upsells you don't need

Dealership service departments frequently push unauthorized additives like oil fortifiers and unverified maintenance additions during routine visits. These unnecessary recommendations inflate repair bills and force vehicle owners to waste time deciphering which services are actually required by the manufacturer.

“Buddy I love the advice and my blood is still boiling from a bad tech experience. Three months after buying our house unit was tripping out, called a “reputable” top rated big company. $850 later I had it charged. Dude said they can leak test for a thousand or just charge it, they weren’t sure how bad a leak could be since we just bought. I opted for just charging it. He also was upselling big time claiming the 7 year old trane starts having a “lot of problems” around that age and we should consider replacement. The upselling disgusts me.”source ↗
