Hi Autocar Team, I am interested in buying a Hyundai Creta, but I am confused between the petrol and diesel variants. I drive around 10,000 km per year, with a mix of short trips, long trips, and city driving. I am concerned about DPF issues with the diesel engine and the mileage of the petrol engine. Q1. How often do we need to drive a diesel car? Is there any rule that we need to start and drive it daily? Q2. If we don't drive the car, will soot still form in the DPF? Q3. If I don't drive the car for two weeks and then drive it only in the city for the next two weeks, how would DPF clogging occur? Basically, how should we maintain these diesel engines? Please guide me in understanding this.
At 10,000km a year, buy the Hyundai Creta petrol. A diesel only pays off at much higher mileage, and its higher price would take many years to recover. The petrol’s fuel bill will be higher, but at your running, the difference is only around Rs 2,000-2,500 a month.
To answer your DPF questions:
No, you don’t have to drive a diesel every day. Soot only forms while the engine is running, so a car parked for two weeks builds up nothing. The bigger risk then is a flat battery. The filter cleans itself by burning off the soot, but it needs heat to do it. That takes 15-20 minutes of steady driving at highway speeds. Short city trips never get it hot enough, so the soot keeps building until a warning light comes on.
Your pattern is the risk. Two weeks parked does no harm, but two weeks of only city driving is exactly what fills the filter. A diesel car owner in your position would need a proper highway run every couple of weeks and avoid switching off midway through a cleaning cycle.
None of this is difficult, but it’s a routine you have to keep up, and with a petrol car you don’t have to think about it.
