2014 hilux SR5 dual cab, had a Steel canopy for ages, most other mods don't change air resistance, but listed anyway:
For the total life 59,301 km I have 9.66L/100km avg worst 13.34L/100km, best 8.68L/100Km
typical is 9-9.5L/100km, lower for long 100kph drives, usually highest headed out to the nullarbor on 110kph roads with hills and headwinds.
pre 2 inch lift, road tyres, from time canopy installed: 9.74L/100km (32,199kms)
2 inch lift road tyres: 9.73L/100km (10,500kms)
2 inch lift Bridgestone dueler A/T (265/65/r17): 9.86L/100km (6,500kms)
so it seems overall none of the mods I've made have made a great deal of difference, but I guess it's usually more where and how I'm driving that is impacting fuel economy the most (on/off road, peak hour/open road, 100kph/110kph etc)
