Just had my car service the long life one. I thought this was meant to be a 20.000 mile one as my counter started off at 19000 something once it had sorted itself out, I have done about 1500 miles its now down to 17k. its now dropping 100 miles everytime I go out this could be just 2 miles. At this rate I will be in for another service in 5000 miles if that. would I be better just to calculate 20k miles from the time I had the service. Its dear enough as it is, dont want to have to be doing 3 services for one really.
