Well I live in houston. Going 55 ish (90KM?), might get me killed, lol. So I have to keep up and go 65-70. which puts my RPMS around 2800. but even in the city 10-11, downhill, uphill. Loaded or unloaded. Same MPG. maybe I should check for a 15 year old gas leak. Always thought they were just thirsty engines.
