Petrol Cars vs Diesel Cars – Which One To Choose

Choosing from the two variants of petrol and diesel puts a dilemma and raises a question mark in the minds of a good number of prospective car buyers. The debate has been raging for many years with supporters on either side unwilling to let the guard down. Facts first, it is plainly the type of usage that determines whether one has to buy a petrol version or a diesel one. Allaying the doubts of either side, each variant has its own share of benefits and it all settles down, to reiterate, depending on every person needs and to be sure, it does differ. As we unravel the pros and cons of both the iterations under various aspects, it is the customer who would emerge in possession of unalloyed details.

The priority for price

Laying bare a straight fact, the diesel cars are quite expensive than their counterparts running on petrol. There is a considerable difference in the price with the diesel variants on most counts pegged at least by a lakh higher than the petrol version. When the factor of on-road price is taken into account the gap further widens as the registration procedure for the diesel variant involves a steep fee. The fee swings in between 1 to 3% with respect to the cost of the vehicle and again depending on the state where the purchase is made. Upping the ante for the diesel cars is the element of comparatively lower price of the fuel retailing in the country which needs to be configured in positively.


The overall expenditure involved in the maintenance of diesel vehicles is usually on the higher side. This does not mean the petrol vehicles do not pinch much, but lesser while pitted against the diesel dependents. The underlying reason for the inequality is attributed to the highly priced consumables ranging from the engine oil to spares utilized in the diesel models.

The Effect on Environment

We live in an age and time where the objective of safe environment is being accorded one of the top priorities. The diesel fuel is free from any form of lead or rather emissions arising from regulated pollutants mainly from nitrogen oxide and carbon monoxide. But this virtue is slashed by the creation of higher emissions of nitrogen oxides and the relevant particulate matter which are flagged for their carcinogenic nature while compared with the petrol based vehicles. Fitting a particulate filter in diesel car enables to have a check on the pollution caused by the vehicle. The quality of burning is more optimized in petrol and this is at times cited as one of the reasons for turning away from the diesel cars.

The Resale Value

Compared to the petrol versions, the diesel cars command a good resale value. And this is explicitly overriding the fact that the petrol engines are long-lasting. The second hand cars of the diesel variant have enough buyers in the domestic market. So, without any guess it has to be inferred the depreciation of the diesel variants is less than the petrol ones.


The diesel vehicles score all the brownie points when it comes to the mileage. A diesel engine does not require a spark plug and this is responsible for the higher compression. It in turn leads to maximum utilization of fuel by the diesel engine as against the petrol engines. Most of the diesel car owners, in foresight, make a purchase in favour of it despite the higher price tag due to the additional mileage it offers and they seem to recover the cost in due course of time.

In a nutshell, it is the usage as highlighted earlier that has a say on the vehicle choice. For shorter commutes the petrol variant is an ideal one whereas for the longer journeys the diesel based model suits the best.
