I had forgotten about the Glenelg Ferry until I saw the turning and fancied it as we had time. So I had not filled up in Broadford / Harrapool. I missed Shiel Bridge by turning left onto A87 (not being familiar). By the time I got to the Jet station at Inverinate we had been on the flashing light 15 miles. I got 21 litres into a 22 litre tank.
