Just finished driving? Don't turn that engine off straight away! 🏎️💨
If your car is turbocharged, turning the engine off immediately after a drive can end up costing you thousands in repairs.
Here’s why:
Your turbocharger spins at upwards of 200,000 RPM and runs at blistering temperatures. While the engine is running, fresh oil is constantly pumped through the turbo to cool it down and keep it lubricated.
When you shut the engine off, that oil pump stops instantly. But the turbo doesn't stop—it keeps spinning on momentum with zero oil pressure. Even worse, the oil trapped inside the red-hot turbo bakes onto the bearings, turning into a hard, gritty carbon buildup called "oil coking."
Over time, that baked oil starves the turbo, destroys the bearings, and leads to total turbo failure.
What to do instead:
After a highway drive, towing, or hard acceleration, let your car idle for 1 to 2 minutes before switching it off.
This gives the oil time to flow through the turbo, carry away the intense heat, and let everything cool down safely while still lubricated.
It takes 60 seconds, costs $0, and can save you a massive repair bill down the track.
