NC Bill Posted February 2, 2011 Report Share Posted February 2, 2011 Just watched the ASA video ROTAX 912 ENGINE INTRODUCTION with Phil Lockwood. In it he advises that if you are going to use 100LL as primary fuel there are 4 things to do to increase engine life: 1- use dinosaur oil - no synthetics 2- use Declan 3- adhere to 25 hour oil/filter changes & clean bowl at least every 100 hours to remove lead deposits. 4- cruise at 5000RPM or higher The first 3 sound pretty basic. Is running at or above 5000RPM generally agreed? Link to comment Share on other sites More sharing options...
