G'day lads. Time has come to dump the factory fill from my 11 XR6T as it's just clicked over 2 years old and done 30K. What's the best method with the FGs? Previous cars I've just dumped from the bung, flush with hose, fill with demin, run with heater on, dump and repeat (until clear). Also, what brand / type are you good folk running? Cheers in advance Rossco
