Actually there is fuel at Islay. Got some last month, think I paid aboot £1.25 litre + vat. But while you're in the area, why not venture 25 minutes up the coast to Oban and get fuel there ? Think it's about £1.15 litre +vat. Prestwick is aboot £1.23 +vat at the moment.
And then, after Oban, you could drop into Mull and get some of Brendan and Alison bambi-burgers !!
