Frequently asked questions about diesel cars

Is it worth buying a used diesel car in 2026?
Yes, if you drive more than 20,000 miles/year mainly on motorways. Modern Euro 6 diesels (from 2019) return 55-65mpg on motorways. For urban-only or under 15,000 miles/year, a hybrid is more cost-effective.
What road tax do diesel cars pay in the UK?
Diesel cars in the UK pay road tax (VED) based on CO2 emissions in the first year, then a standard annual rate (around £190/year for most cars registered since 2017). Pre-2017 diesels pay a CO2-banded rate. Diesels not meeting RDE2 standards face a higher first-year rate.
How long does a diesel engine last?
A well-maintained diesel engine can last 250,000-400,000 miles. Mercedes, BMW and Volvo are known for durability. Key: oil changes every 12,000 miles and filters as per manufacturer schedule.
What are common problems with used diesels?
Common issues include clogged EGR valves, worn turbos, injectors and diesel particulate filter (DPF). Check service history and do a long test drive. Diesels under 100,000 miles are usually fine.
Will diesel cars be banned in the UK?
The UK plans to end sales of new petrol and diesel cars by 2035 (new pure petrol/diesel by 2030 under current policy). Used diesels will remain road-legal for many years. However, Clean Air Zone and ULEZ charges may apply in some cities.

Your next diesel car, hassle-free

Yes, diesels are under scrutiny, but let's be realistic: if you do high annual mileage or your journeys are mainly on the motorway, a used diesel is still a very sensible economic choice.

When a used diesel makes sense

If you drive more than 20,000 miles a year and most of it is on the motorway, the fuel economy of a modern diesel is hard to beat. A Euro 6 diesel (2019 onwards) is cleaner than you might think and offers incredible efficiency at 55-65mpg on the motorway.

That said, if you live in a city centre and drive mainly in urban areas, a hybrid might work out better for you. Diesel shines on long journeys where its 55-65mpg really makes a difference.
