That's very good, I have a strange sense of satisfaction when running a car to high miles, like I'm sticking two fingers up to the modern car industry, keep it going!
I have been waiting for this number to come up. Fortunately I was at Gravelly Hill on the A38 in Brum rather than a mile further on the A38(M)!
Of course hubris caught up with me 2 miles down the road in the underpass tunnels in town; the gearbox slipped into neutral as it changed down as I came to a stop. Manually popped it out of D, into N and then back and all good again but clearly I need to dip check the gearbox level.
On the contrary, I'd say that it's a testament to the modern car industry and the fact that car design has reached a point where pretty much any vehicle should be able to do a few hundred thousand miles without major incident.
As for the modern car sales industry, that's another question...
Gearbox update - added 100ml of fluid without dip checking and everything does feel smoother. When is get round to it I will get it dip checked too so am keeping the extra fluid in the boot for that moment
