Re: E 85
Sadly, E85 while it uses a more renewable source of energy, does have a lot less energy per volume unit than normal 87 Octane gasoline.
Really, though, getting better fuel economy is something that doesn't change with the type of fuel you're using.
* Don't stomp on the gas. Ease into the pedal when possible.
* Let the engine do the braking as much as possible, and slow down early. When reversse torque is applied to the engine, the PCM cuts fuel delivery to a minimum. If you have a manual transmission, holding the clutch in or putting it into N while slowing down actually takes more fuel than letting the engine do the braking. If you slow down earlier your engine spends more time under negative torque and burns less fuel.
* Shift early. This goes with the rule about leadfooting it. Once you're moving, stay in the highest gear you can. If you have an automatic transmission, leave overdrive ON and leave it in the highest gear possible.
* Make sure your tires are properly inflated. Underinflated tires don't roll as easily and will adversely affect fuel economy.
* A/C puts a load on the engine. when possible, don't use the A/C
* Driving with the windows all the way down creates excessive aerodynamic drag. When possible, leave them only slightly rolled down. Rolled all the way up is best.
* Slower is better. Especially with the massive frontal area that our trucks have, faster speeds dramatically increase drag, which increasingly adds to the amount of effort the engine needs to supply to maintain a given speed. Also, higher speeds in top gear run at a higher RPM. Past 100 km/h or 60 MPH, your fuel economy will get worse and worse the faster you drive.
* Avoid stop and go traffic or erratic traffic speed changes. Keeping a steady RPM and speed is essential to getting good fuel economy. Learn how to time stop lights and flow with traffic. Use highways when possible.
Best of luck, and thanks for using E85!
