Wow! Well caught sir! As an aside I am staying in a (US) hotel at the moment where there is no 13th floor (button) on the elevator (lift to us folk) it goes 11,12,14... Now I'm pretty sure there is not a "thirteenth" floor laying empty so with my Engineer's logic I'm think the 14th floor remains the 13th in the real world?

Likewise Ryanair (and probably others) delete row 13... (Signage only)

All that nonsense aside I reckon you will be good for many more miles with regular fluid changes! Well I hope so anyway since I'm in the same boat as you
