Diesel or Petrol? It is a question that every prospective car buyer is confronted with. Virtually every other carmaker has a separate diesel and petrol engine option for its lineup of cars and in the end, it all comes down to personal options, driving demands and the economy. Rule of thumb here says that though expensive upfront, Diesel motors are proven to provide better gas savings than their Petrol counterparts. Add to the fuel speed gap between the two has always been north of Rs. 10/litre and also for big tank fuel guzzler diesel which do matter.

Honda learned it the hard way when it lost a great deal of market owing to the lack of a diesel engine in its portfolio and had to give in eventually, with the introduction of its i-DTEC diesel motor, which now does rounds in its existing offerings. In a market as diverse as ours, there is a fair discussion of the two petrol and diesel on the roads. Petrolheads argue that diesel engines tend to expire early, are eerily high on NVH levels and require regular maintenance to keep sailing. Better yet not, we love our diesel automobiles and in this section, we talk about the way you can happily (and easily) keep your diesel car.

But before beginning on our tips lets first understand why and how are diesel engines distinct from petrol or other gas engines, for that matters.

Diesel engines are, like petrol, depending on the principle of the internal combustion. The identical drill, air goes inside the room, gets compressed, the temperature is raised and the gas then pumped burns off to move the pistons. While a normal petrol engine permeates the atmosphere by approximately 10 days, a Diesel engine does even more work to compress it by a factor of 25-30. This produces enough heat to ignite whatever little fuel is injected into the system in agreement with the energy demanded by the motorist. In the procedure, the need for spark plugs is also bypassed.

Since it does more work, there’s an exponential increase in the wear process the car manufacturers have to counter. Better mechanics and high-grade materials translate into increased costs and thus, the engines powering the pricier cars in the segment churn out relishing performances on the streets.

Diesel Engine Car Maintenance Tips

Every car needs maintenance and it holds good for our cherished diesel automobiles too. There’s just this set of general advice/tips for maintaining your car immaculate and registering more miles from the odometer. These are, naturally, general information, which holds great for most diesel cars out there but not all, as the difference in mechanics and motor parts exist among different manufacturers.

Changing your Driving Practices

    Diesel engines don’t have spark plugs and ignition is based totally on the battery power, so it becomes all the more important to utilize minimal of the car’s electricals (most significantly the AC) while turning to the Car.


  • PREHEAT: Your diesel engine needs to create some initial heat to operate. Most cars today come equipped with a preheating mechanism and everything you have to do is wait patiently for the preheat’ index to go off before turning the ignition. During winters, it helps to heat the motor for 5 minutes before gaining momentum.

ENGAGE THE CLUTCH DURING IGNITION: This helps reduce the load on the starter motor, which has the work of kick-starting the heavy diesel motor to life. Helping the engine by simply engaging the clutch will ensure long term longevity and a decrease maintenance bill in the future.

Higher revs over the 4000-5000 mark generate more sound, kill fuel market and don’t generate equal power to nonrev driving. Keep the revs low around 2000-3000 rpm mark and you may be certain of keeping your engine happy.

  • Service & General Maintenance
    Every once in awhile your vehicle should juice up, rather than always on diesel only. Bi-annual or quarterly support schedules should be followed closely to top on motor oils, coolants and for changing of air and oil filters. Gaskets need special attention during these solutions.


    Tyre pressure vastly impacts the kind of performance you receive from the engineĀ and consequently, it is highly advisable to maintain the tire pressure kept in the optimal amount indicated in the car manual.


    A dry engine may stall any time along with the fuel pump stops. Manual distribution of fuel into the motor is necessary to start the engine. There is also a chance of rusting related to conducting a dry engine. Some contemporary engines now scatter the supply below 2-3 liter of gasoline as a security mechanism.

With good maintenance and regular support, diesel cars may give their gas counterparts a run for their money. But having said that, Diesel are taxing on the environment and petrol cars are much cleaner and more economical because of sense. Aged diesel engines are a menace for the atmosphere and so, a car that has passed its life is better disposed of.
