I have learned the secret to getting over 24 MPG on the highway. I live in a hilly area so I was happy with 24.8 mpg on the hghway and if I was driving in some place flat, I think I could do even better than 25 MPG. I took the car out at night, on the freeway. I did this for about 3 weeks till I figured out how to consistantly get over 24 MPG. For anyone who wants to try what I am about to propose, please be safe, and do it when there are very fiew people on the road. To figure out how you should drive your landcruiser, first take it out at night, after 9 PM on a weekday to a nearby highway that should be mostly empty. Second, reset the gauge that has the MPG to zero. Next do not have the trip miles gaue up, this does nothing to teach you how to drive the car. Change the gauge in this video ( ) that has the trip miles to the one that has the Turbo BOOST (not electric boost showing batteries). Now start driving. Your goal is to drive without spinning up the turbo, or if you must to get to speed as quick as possible, and then lay off the boost. What you will see is when you glide- the whiteline on the mpg gauge goes to 60 mph(and your rpms will be 0), when you push gas, but do not activate the boost gage, you will be below the blue line or it may be above the blue line close to 30 if the battery kicked in. Now the important part, drive while trying to maintian spead and watch the turbo gauge- the goal is to not spool it up at all. Then drive and experiment with increasing speed to feel how the vehicle reacts when you jump up in speed (watch the spooler) and then level and maintian your speed....this will help you learn how your spooling and mpg is effected and its correlation to your actions. once you think you have it figured out, take it out the next night and try again and see iff you keep getting the same results. Like I said I am in a hilly area so that means 50% of the time I am going uphill, and 50% I am going down hill on the way back. In a flat place, I think you can do better than 24.8 mpg.
