What mode do you drive in?Took the stock gx OT on the freeway for a 40 mile loop. Going 65mph , 29.7 on the way there and 22 coming back . That’s 26mpg combined. As for city driving on I’m getting 2 mpg less compared to stock lc, averaging 15
I live on high elevation and driving to work is a 6 mile route with many lights , going down to work I get 19-24mpg and the drive back 12-15 depending on how many red lights I encounter with total city average around 16 . I’d say my numbers are on par with motor trend 75mph test which returned 21mpg
