Might not be recommended (for obvious reasons - they want you to buy their own over inflated oil) but works fine.

Plus it costs me £5 a litre. Can see no point spending more than is required. Mobil 1 is widely respected, and has worked fine in all of my cars - literally since I started driving.

I can get Castrol oils at similar prices, but I've stuck with what I know. The previous owner used the same oil, and I thought I'd stick with it as the car's still running, and not using any oil (well, 500ml in 5000 miles.)
