its just you were saying use millers xf longlife 5w-30 and then said about using millers sport 4, after i mentioned flushing the engine. so i was confused as to what you meant.
does some of the oil get stuck in the oil cooler, is there even one on these cars? will i need a 1ltr top up, as i make it 5.2ltrs total. or like my 850 will it usually not quite take all the oil before reaching the max mark.
wheres teh cheapest place for the quantum stuff
Went to the main dealer to day for a service kit and they said that they use 5/30 in the pd engines and charge £14 a liter which i think is a lot of money.
£14 a liter is a lot of money.... in fact that is an incredible amount of money for any motor oil, no matter how good it is. Try other suppliers.
In your case I'd suggest not. The oil they used was a pd engine specific oil, and it was changed every 5k miles, twice as often as required. It was a slightly thicker viscosity grade than Seat require but at least it was specific to the vag engine, and Repsol make a decent oil anyway.
