The debate at the pumps has been raging for years. But how do you choose between petrol and diesel power?ring up this subject and you will quickly realise that there are no grey areas in drivers' minds on the matter of petrol versus diesel. As both diesel and petrol technology improves, the difference increasingly comes down to personal driving preferences.One group will insist that petrol is far better, largely because petrol cars are faster, quieter and cheaper. Diesel fans will, of course, highlight the vastly better fuel consumption plus the improved torque from a diesel engine, which gives good pulling power and less gear changing, making driving in everyday, rather than race-track, conditions a pleasant experience. There are also the muddy waters of exhaust emissions, with strong arguments on both sides of the fence.
So what is the objective truth? Diesel engines inherently use less fuel than petrol cars, and so will undoubtedly save you money in the long run. This is particularly true in town driving, if you make a lot of short runs, or if you do towing, where the differences are even more marked. On long trips at motorway speeds the differential closes. Diesel fuel in the UK is usually priced close to unleaded petrol, so figure out the difference in hard figures comes down to a straight MPG comparison. However, if you travel a lot through France, you'll find that diesel is approximately two-thirds the price of petrol, enhancing the savings even further.
