Petrol?? That's doing well lol! Well like said can get 10w40 cheap as from work fully symth! So ill prob go for that to be honest.
both petrol, came the conclusion that 1.8T motors are really reliable once you have a spare and don't care if or are expecting it to pop then they magicaly become indestructable. spend money time and or effort on looking after them they seem to ether clog there oil pickup or drop a valve ether way renders them scrap
both those engiens were abused to hell on bargain basement 10/40 semi synth AC DELCO mixed fleet oil
th enoticable diffrence was a lack of tappet rattel when cold and they din't burn any unlike 5-30, only real differance is the 10/40 is going to be thicker when cold cost you a bit of fuel economy on cold engine but the tappets won't bleed down over night if there a bit tired
