To all those new Gladiator owners. I am using E10 as recommended here in Australia which is 94 octane. I am struggling to get below 20L/100km which equates to 11.76 US mpg. I don't drive erratically. Most of the driving is around town at around 50 - 60 km/h. I find the gearing seems to hold the revs too high also. On a long trip cannot get below 15L/100km or 15.68 US mpg. Any tips would be appreciated.
