It's a Hyundai CRETA/ ix25 model... clocked 1800kms on the odometer, diesel spec engine 1.6 crdi unit, manual transmission! It has redline at about 4800rpm in the tachometer. When i took it for service! the idiotic mechanic FREE REVVED the engine upto 4000rpm for 2-3 times:@ both in neutral and in running the vehicle with clutch in ... i've heard that free revving an engine damages it!

I felt really annoyed. Does it eat up engines life?

I'm worried!...Please help

    Short answer - no. It's perfectly okay. And , it's also perfectly okay to be annoyed. It's one of those things mechanics like to do (no offence to anyone). Similar to endlessly hitting refresh on a windows machine. Your car has a rev limiter and unless you've crossed that by downshifting, there's no need to be worried.

Short answer - no. It's perfectly okay. And , it's also perfectly okay to be annoyed. It's one of those things mechanics like to do (no offence to anyone). Similar to endlessly hitting refresh on a windows machine. Your car, as do most modern cars, has a rev-limiter and unless you've crossed that by downshifting, there's no need to be worried.

Please comment if there's anything you'd like me to elaborate on.

    I remember "mechanic friends" doing this to my car and my dad's car when we asked for their help and it really annoyed us. There might not be anything wrong with it, but when you're in the "try and take it easy on the car" mindset, this is infuriating.
