Right, my car is going in for a service next week and I'm changing the oil from Mobil 1 due to the extortionate prices (£35 for 4 litres - £11 for 1 litre top ups, give me a break!!) Normally I buy stuff for the willy regardless of cost, but Mob1 seriously piss me off with their 4L bottles (and then a seperate 1L for oil changes, it can't be that much better then other synthetic oils can it?) Plus it's so difficult to get hold of, the only place I've been able to source it is Halfords. I've heard people on here say they use Total Quartz 9000 fully syn which is the same as Elf oil, what grade do you recommend, I'm currenty using 15W/50 Mob1, which was recommended by the previous owner, but to be honest the car runs like shit at idle (not sure if it's to do with the oil but never runs smoothly until it's warmed up), and I've been told a few times this oil is too thick?
Help would be much appreciated!
