My oil pressure shows in the middle when idling before a trip. After a 20 mile cruise and taking it out of gear it's one bar down from where it was. I've checked it cold and it shows in the safe zone on the stick. Is this due to the oil getting hotter and thus shows lower pressure? Anyone else experience this? I put many miles on it running 25-26 knots at 4100-4300 rpms. Do they use oil? My 225F never seemed to use oil between changes. My oil was changed int the fall by Yamaha tech.
