Frequently asked questions about diesel cars

Is it worth buying a used diesel car in 2026?
Yes, if you drive more than 20,000 km/year mainly on motorways. Modern Euro 6 diesels (from 2019) consume 4-5L/100km on motorways. For urban-only or under 15,000 km/year, a hybrid is more cost-effective.
What road tax do diesel cars pay in Ireland?
Diesel cars in Ireland pay motor tax based on CO2 emissions. Newer diesels (Euro 6) tend to fall in bands A3-B1 (€190-€270/year). Older diesels may pay higher rates based on engine size.
How long does a diesel engine last?
A well-maintained diesel engine can last 400,000-600,000 km. Mercedes, BMW and Volvo are known for durability. Key: oil changes every 15,000 km 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 km are usually fine.
Will diesel cars be banned in Ireland?
Ireland has no announced ban on diesel cars. The 2030 target is for new car sales only. Used diesels will remain roadworthy for many years. However, urban restrictions may increase over time.

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 km 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 4-5L/100km 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 4-5L/100km really makes a difference.
