95 or 98 ron?
My new 02 A4 1.8T sport 163ps states that it needs 95 Ron fuel, it doesn't mention 98 ron for this engine.
I usually use Optimax or BP Ultimate because of the cleaning additives and increased mpg, but is there any point with this engine/ECU? Will the ECU adjust for this fuel or will I be wasting my money?
Re: 95 or 98 ron?
Mine also only states 95 Ron but i continue to use the better quality 98. I have noticed the performance increase even if it is ever so slight. At the end of the day its a better fuel for your engine and for the extra 200 quid or so a year that it adds on to my fuel bill then what the hell if its better for the engine!
