Oil leaks again

Took the car to a family get-together - 80ish mile round trip - all good but it's sprung a leak from the remote oil filter again ho hum.

That aside is cruised at an easy 65-70 although it was very windy and I got grit in my eyes a couple of times. I'll be interested to find out how much of the 23 quid or so's worth fuel I put in it I've used.
