84 4runner LS400 ECU/Engine (91) using supreme fuel in the US and it is getting about 15L/100KMs. This is with a guage that is accurately adjusted for fuel consumption AND speed. I am able to see instantaneous mileage/consumption as well. The engine reports "running" as normal when put in to diagnostics mode, not to mention it runs very well. Running the R150F manual transmission. 37' tires with 5.29 gears (switching to 4.10s and downsizing tires 2-3").
I get better mileage in town lugging around than on the highway. Most likely due to the large tires (37 Toyo MTs on steelies).
The 1UZ can be a very efficient engine, from what I've seen and heard, if it is fit with an aftermarket ECU. I've been told it runs quite rich with very conservative timing. My belief is that there should be quite a bit of room for improvement with an aftermarket ECU.
If putting the 1UZ in a truck with large tires, this is about what you will get. Don't expect or think it will be better. It might get a little better with 4.10 or other gears, but I still don't think it will deviate much. Even with the 5.29s I have to give it a decent amount of throttle to keep 'er moving on the highway.
