what spec/brand of oil do you use and where do you buy from?
i've always used a semi-synthetic for my standard 8v
is this ok or is there anything to be gained from using something more advanced/expensive?
where is the cheapest place to buy oil from (not halfords - too expensive!), i'm guessing main dealers is a rip off. is GSF any good?
in the past i've paid around £12 for 5 litres
