To be honest have been using unleaded, not had any issues. Tony (Tcwozere) and myself went round to Drivers Wharf today to get the rib weighed, averaged 40 knots both ways, 50 knots at one point back down Southampton Water and used total of 28litres per engine which I thought was very good considering we did 40 miles.
