What should I do if I misfuel?
What will happen to a Land Rover Discovery 3 if it's misfuelled?
Depends on how much of the wrong fuel was poured in. Less than 10 litres, a dose of diesel treatment with lubricity enhancer and the use of superdiesel from now on and forever may help as long as you do not let the tank run below half full for 2000 miles. More than 10 litres, I'd start to worry and have the tank drained.
