Mechanic says turning off one thing in your car can 'double the life of your engine'

A driving expert has claimed a simple adjustment could "double the life of your engine".

With over 50 years of experience as a mechanic, Scotty Kilmer has suggested that a widely used feature in modern vehicles may actually be harming their performance.

In a YouTube video, he advised drivers to switch off the auto start/stop setting on their cars.

Although this feature has become popular due to its promise of improved fuel economy and reduced emissions, Scotty contends it may increase engine wear.

He asserted: "[Turning it off] is a smart thing to do. Start/stop technology is the dumbest thing that's come out in years. 97% of the wear happens when you start the car so do you want to keep starting and stopping it? Not if you want your car to last longer."

The stop/start function can typically be deactivated using a distinct button located on the dashboard, often marked by an 'A' encircled by an arrow. A small light usually signals when the setting is turned off.

After hearing Scotty's advice, social media users were left amazed, reports Birmingham Live.

One user shared: "I recently was driving a rental with this feature and after realizing it wasn't the car stalling at every red light I realized what was going on."

"I thought this was... worse for the engine than just idling."

Another chimed in: "I test-drove a car once with that function and I found it annoying."
