Until January 2006 I had always had my car regularly services by a dealer, I won't name them, but you don't have to 'Look' very far.
After that I have always done the serviceing myself, with major jobs done by Mark.
The first time I came to change the oil, I had to get the sump plug off using a breaker bar, and the oil filter off using a filter wrench.
In January 2007, MOT time, I let a different dealer change the oil and filter, to get my service book stamped.
3 months on, oil change due, and guess what, breaker bar to remove the sump plug, almost completely knackered (good job I'd got a new one), and filter wrench to remove the oil filter.
Why did I bother for the sake of getting my service book stamped.
