Petrol or Diesel Cars
Petrol or Diesel Cars?
The decision from a cost saving perspective as to whether you should select a petrol or diesel car or van is not just dependant on the cost of the fuel per litre and the mileage you will do each year so let us look at the factors you may need to consider before reaching your decision.
Fuel prices
Currently, here in the UK, diesel is several pence more per litre than petrol but the gap does vary. On the plus side a diesel does more miles to the litre than a petrol vehicle. The number of miles you do each year could have a major impact on your decision which type of fuel to go for. As a rough rule of thumb you may need to be driving at least 10,000 miles per annum to make a diesel car potentially more cost effective that a petrol car assuming that you will retain the vehicle for 3 to 4 years.
Residual value
The residual value of a diesel car tends to be greater than that of a petrol vehicle especially at the moment with road tax tending to be lower for diesels and better fuel economy (subject to the above).
Car tax
Because of lower CO2 emissions diesel cars have lower road tax charges than the petrol version of the same vehicle.
Servicing
Diesel cars tend to be more expensive to service and repair although the periods between servicing can be longer than that of petrol.
Some people are of the opinion that diesel engines are more reliable but nowadays there is likely to be nothing to choose between them.
There are a number of websites that allow you to calculate the period of time to re-coup the cost of running a diesel vehicle when compared to that of a petrol car making numerous assumptions that you may find useful
