I later took the governer off started crusing at 67 mph and rpm went up to 1500 1/2. At 70 mph the rpm is at 1600. I don’t really run it there unless I want to pass a truck or car quickly. When doing 70 through the rpm sounds really angry and loud so I always thought that was too much. Runnig at 67 I get good fuel milage especially on i10 and i20 because it’s flat. When grossed out if you don’t punch the rpm up to 1700+ when catching up to road speed youll be really slow. Truck is not deleted also

How much is the fuel consumption with gear lower revs 1600-1800 cruising at 55mph vs 65mph and 1400rpm.

55mph means less fuel consumption, less wear, more time to react to something unexpected happening
