Cheeky monkey.....
That's right I now spend less time putting oil in and instead cleaned the windows on the car as I ran out of time to clean her for the next 1,600 miles this week. But I'll give her a clean Wed night me thinks.
(I did pop half a litre into the engine, which now shows full, so we shall see what difference there is now in the mileage before top ups rather than refills)
Thanks BTW
