Driving with load allows the gas engine to run in a more efficient regime.

If you can find it, look for a fuel consumption map for your particular engine.

I drive a Honda Insight, and the BMSC map for my engine shows that I should run between 1500 and 2500 rpm, and about 80% throttle for the greatest engine efficiency.

I use this approach when going up hills and getting up to speed.

Using DWL is the most effective way to work with EOC, Engine Off Coasting. When I do that effectively, I get over 150 mpg in the summer months.

HTH, Jim.
