I won't pay for your gas just to prove something thats already been proven many times over. However, I will explain it to you. WOT (actually, as much throttle as you can get without going into closed loop mode) combined with short shifting is where you see the gains. High engine load with low rpm is what gives you the best efficiency. This is how the MPG challenge racers do it. Even with your 300hp engine, your not putting out massive horsepower at 1500 rpm, so your not going to break your tires loose. If you are spinning your tires at that rpm/load you engine is way too powerful for your car. Also, wear isn't a big deal as torque will also be low at real low rpms. Combine that with low piston speeds due to low rpm and you actually have less wear on components.

Now, there is one shortfall and that is that you can't do it with an automatic transmission since you can't combine WOT with short shifting. In this case you have to make due using fake or false shifting technique.

Nice and easy driving does it, that's the best way, it's the only way.
Tell that to the guys getting 10+mpg over EPA's highway estimates using P&G.
