I get around 500 miles in the GTD but can be more/less depending on conditions/journeys by + or - 50 miles
Based on £1.40 litre for Diesel and £1.32 for Petrol and 500 miles / 350 miles per tank respectively, the cost per mile is around 15p for diesel and 21p for petrol (just the fuel not any other running costs)
Question: Is the 5p per mile extra for a petrol enging worth it to you or is the 5p per mile saving for going GTD worth losing the petrol engine?
^^Hope that makes sense?
