I've got 3 bottles of redex that i havent used yet, but today I put 40 litres of BP ultmiate into my car, meaining that there was about 15 litres of (ASDA) regular diesel still in tank.
Wondering if its worth me putting a shot of red-ex in as well to boost cleaning properties, or could this be overdoing it and cause problems?
