Possible 6th GEN 4TR in 2016?

When I got rid of my 20's and put SR5 wheels and stock size on I saw zero difference in mileage. Driving in Cali versus Canada probably makes a bigger difference.
lol, what do the wheels have to do with anything? I never mentioned them in that context. I do run 17s in the winter, but I don't notice a difference either. I suspect the difference in mpg is due to the full-time 4wd and extra weight associated with the LE. I found the SR5 pulled itself along more effortlessly, again probably because it has 2wd.

As for the fuel, each regional jurisdiction imposes their own rules. California does not require ethanol in gasoline, but neither does Nova Scotia. Some stations in Nova Scotia do have ethanol gas and I understand it's widely used in California. Our local refinery actually refines gasoline to the same standards that is required in California so I can't imagine there is much difference.

The mountain passes and elevation changes on those Cali highways is way more significant than anything I see around here.

Sorry my post didn't really explain what was in my head, haha. When I switched to the stock SR5 wheels/tires I was still getting the great mileage you got in that truck. I averaged close to 20mpg in mixed driving and could easily get low 20's on the highway with my limited and 265/70/17's driving around Denver and up into our mtns. This was all before I bolted a bunch of steel to it, lifted it, and put these heavy Duratracs on.. Still getting 18mpg now with mixed driving.
 
But there isn't a milage difference between all the grades of 4runners currently. I suppose that could change, but you're still dealing with poor aerodynamics and body on frame weight. It's a truck, more specifically - it's a land cruiser in a different body.

There is. Awd has more driveline friction. All else equal, the LE gets worse mpg than a sr5 in 2hi. Smaller lighter low resistance OEM tires on the LE help it match the other models. The common reports indicate part time 4wd conversions on most land cruisers return 1-2mpg.
