Re: Diesel mpg - way of driving? the days of changing up ASAP are long gone. Years ago you really would reduce engine life if you ever went over 3000rpm.
Those days are gone. Engine design has changed and has moved on.
Fuel usage is affected most by driving style than any other factor in the equation.
Some drivers can wring 40mpg plus from a 4 litre petrol car with automatic transmission.
Others can struggle to see 30mpg from a 1.2 litre supermini.
Neither is wrong. It's just folks and strokes. |
