•4wI own a 2019 Ford EcoSport diesel and am planning to switch to a petrol car, as my daily commute has drastically reduced. Since the EcoSport is a 1.5 TDCi turbo-diesel, I am used to its power and torque. My daily runs will be less than 8km and a maximum of 300km per month. Will such short runs affect a turbo-petrol engine like the one in the Mahindra 3XO (Turbo Multi-Port Fuel Injection)? I have heard it requires a cool-down method of idling for a minute before starting and stopping the engine, which might be cumbersome on a daily basis. I hope there are no DPF-type issues in a turbo-petrol engine with low usage. Please suggest whether I should opt for a naturally aspirated engine with less power and torque to avoid potential problems due to low usage.

In general, it is a good habit to leave the engine idling for a few seconds before shutting it down. This is because turbos spin at extremely high rpms when driven. Shutting down an engine stops the oil circulation while the turbine shaft is still freely spinning due to inertia. Thus, leaving the engine to idle allows the turbos' revs to come down, while the lubrication system is still on.
Earlier, you had to leave turbocharged cars idling for about a minute, but with today's modern engines and advanced lubricants, it is generally recommended to leave them on for just a few seconds. So, you can safely buy a turbocharged car, just remember to shut down after a few seconds while you unbuckle and gather your phone and other items.
