Should I buy diesel or petrol?Back

PetrolvDieselThere are many pros and cons to buying both diesel and petrol cars but it is your individual circumstances which will ultimately determine which type of fuel is right for you.

Petrol is currently cheaper to buy at the pump in the UK, but diesel uses less fuel so you can effectively travel further, hence the reason why some motorists struggle to determine which type is best.

Ultimately, our advice would be this – if you are buying a used car, opting for a petrol engine is more cost-effective despite the gap in fuel efficiency. The main reason for this is the buying price.

In general, used petrol cars are significantly cheaper to buy, so unless you are covering a large amount of mileage, and planning to hold onto the car for a number of years, you may never make up the difference in the price of a more expensive diesel model.

For further information on whether a diesel or petrol car is the right choice for you, take a look at some of Trusted Dealers facts below:


Cost – is less to buy and at the pump.

Durability – petrol cars have the ability to last longer in between services providing they are well looked after.

Fuel – not only does it cost less but you are less likely to make a mistake at the pump!

Choice – if you are looking for a second-hand car, you’ll find more choice of petrol cars than diesel, which adds to the reason why they cost less to buy.


Economical – you should be able to achieve around 10 miles more per gallon than a petrol engine.

Greener – Diesel cars are kinder on the environment offering less CO2 emissions, with some less than 99g/km which exempts drivers from paying road tax. If you drive a company car you’ll also pay less car benefit tax.

Shelf life – is longer as diesel engine cars are built to run on lower revs which preserves their life better.

Cost – if you buy new, diesel cars will generally cost more. Second-hand models are still usually more expensive but prices are becoming less competitive as the demand for diesel cars increases.
