While filing my ten year old ford escort van with diesel this morning I was looking at the price of petrol.
I got thinking about a 90% diesel 10% petrol mix similar to what is suggested in the handbook for winter use.
Taking in mind that this would increase the calorific content of the fuel, what would you opinion on using a mix of this for a prolonged length of time.
I was thinking of a slight increase in engine wear (not a great concern with a ten year old rusty vehicle) against a small increase in power and fuel saving being able to go up the gears more quickly.
