Coming up on 4000 miles on the Silkolene Pro 4 15W50 in the Duc and the shifting still feels good, valve train still quiet (quiet being a relative term with the Desmo bits). 150hp liquid cooled, oil cooled, shared sump 1200cc 90 degree twin, 11K redline for those not familiar.
Back when I switched to Silkolene, the tech rep for Fuchs said Pro 4 15W50 will go the 7500 mile manufacturer's OCI. Of course, I won't run it that long, but I am kicking around going to 5000 on it then change and UOA.
