I've just been quoted £109 by Arnold Clarks St. Helens for my 24K service - thats bringing my own oil. From doing a quick search this seems to be quite a reasonable price and from the the few times I've been in to AC I'm very happy with their service and work. First Q is (and this is because I've become a lazy sod and can't be bothered doing another search) which oil do i get? I'm not mechanically minded so a short explanation will also be needed. 2nd Q how much do I need and finally where do i get it from Halfords/Motorworld etc. Will be done just in time for the NW late run so it will be purring nicely when up in them thar hills.
