You're doing it like the engine was designed to be run. Good on ya! Not only are you saving fuel and running the engine efficiently, you are operating it under less stress and lower heat, both of which are compatible with durability concerns. Have you run a GAMI lean test? If so, what is your GAMI spread? If not, please do one and let me know. Thanks.
