Thanks Graeme, I didn't take it as a criticsm at all just explaining it for dad who read it out of context between posts I think you could well have a point, I do ask an awful lot from the car, we covered over 500 miles in 24 hours last weekend, and absolutely thrashed it on track all day long with very little down time between sessions, as it simply didn't need it. After one session, dad and I swapped round, and went to head straight back out. One chap asked me as I was jumping in 'arnt you even going to check it over?' I said, " oh yea, great idea" Opened the bonnet, no oil or water visible on the outside. They must still be inside then.... 'yup, it's still there!' Shut the bonnet and headed straight out Didn't use a drop of oil all day, didn't fill the catch can, just worked, perfectly. Still so happy with it.
