Should I idle the engine of my petrol car after a long run just like you advise for turbo diesel owners?
You have wisely advised owners of diesel turbo cars to idle the engines after a fast run before switching the engine off. Is the same advise also applicable to petrol TSI cars, such as the Volkswagen Polo 1.0 TSI (110 PS)?
Even though turbos in petrol engined cars are always watercooled (as well as cooled by engine oil running through the turbo bearing), it's still wise to idle them for 30 seconds after running on the motorway, after a long ascent, or after towing.
