I desperatley need to oil change my recently purchased mk1 cupra 1.8T (180). Nxt weekend ideally! Castrol, Millers, and Shell aside, Quantum seems to be the oil that you can't go wrong with according to weeks of reading forums, making phonecalls, and umming and arring! I've been on the quantum website (not sure how i did that because i can't find it now - but i took notes). And ive whittled it down to Quantum Platinum 5w40 being the most suited. They also promoted longlife, but i just don't like the sound of that! But when i check on web for prices, the platinum sellers seem to advertise for the diesels. Does anybody use this oil in there Cupra 180 petrol?
