Very true Steve! Always service my cars in the autumn, so they are ready for the winter, and then again in spring if I think I will do over 10,000 miles in the year.
I know that the VW507 oil is good for much more than 10,000 miles, but I would rather change twice a year if I am doing 15,000 miles.
I also missed out the step of sticking the kettle on afterwards, so apologies for it not being utterly comprehensive.
