Overview
- Scotty Kilmer, who posted a YouTube video Tuesday, told drivers to disable auto start/stop and said it could double engine life.
- He argues most wear happens at startup, citing a claim that 97% of engine wear occurs when the engine fires back up.
- He also warns that frequent restarts can strain starters and smaller lead‑acid batteries that are not designed for constant cycling.
- Articles explain the feature can be turned off with a dashboard button marked with an A in a circular arrow, with a light showing when it is off.
- Start/stop exists to save fuel and cut emissions, but the reports include no independent studies or automaker comments to verify his quantitative claim.
