Petrol and diesel, to the untrained mind, might seem like the same thing, anyway. What’s the big deal, it’s all oil, anyway, you might ask. But there’s a whole ocean of science behind it – what with the kind of impact their usage has on the world around them. What would work more practically for you, as a vehicle user? Here’s a comparison of Petrol and Diesel usage!
- Petrol is expensive, while diesel is more pocket friendly. This shouldn’t come as a surprise to you if you’ve known and seen enough people whose eyebrows disappear into their hairlines when they read about petrol price hikes. The key is to identify what works for you in terms of your budget.
- A second factor is to understand how much your usage itself will be. Are you likely to use your vehicle to travel about 70 kilometres and above in a day? Then diesel makes more sense, while for all other kinds of minimised travel, petrol is your buddy.
- If you have a vehicle for personal needs, you should be best off with a petrol variant, but a commercial vehicle gains more from a diesel fuel engine. According to a research study by the folks at CRISIL, buying a diesel car makes economic sense only if justified by usage.
- If your concern is with mileage, diesel makes sense if it is for a bigger car. Typically, a car with a couple of litres petrol engine will give an average mileage of eight to nine kms a litre, while a diesel variant will give an average of 20 percent better mileage!
- Your manufacturer preference can also alter your choice of fuel – a car that is European in make works great with diesel engines, because European vehicles are more diesel centric. But Japanese and American vehicles are petrol centred.
- A petrol engine doesn’t last as long as a diesel engine, so if your concern is about the engines you will be working with, your best bet is to indulge in diesel.
- Another concern would be the depreciation cost, or the value that a car loses over a certain time period, expressed in monetary terms. Petrol cars tend to be better performers when compared to diesel cars, but even in such situations, the demand for second-hand diesel cars in the domestic auto market is far more. That is why the depreciation cost of petrol cars are more compared to the diesel ones.
- The crown jewel in your decision making, though, would be performance. In general, petrol engines are considered to be far more efficient, as they can operate at high revs (RPM), due to lightweight parts. Moreover, petrol engines use spark ignition while diesel engines use compression ignition. So, they have smaller compression ratios and have better performance capacities.
