Do diesel drivers subsidise the price of petrol?
You probably won't remember a time when diesel was cheaper than petrol in the UK. It was 1990 when the tables turned. Over the last 15 years, diesel has averaged 4.3 pence per litre more than unleaded petrol. At the peak of the price gap - in 2008, garages charged a whopping 15 pence per litre more for diesel! So why the difference when both diesel and petrol are made from the same feedstock, via the same process, by the same industry?
