We are comstantly searching for ways to increase fuel milage, of course when you are employing company drivers you have those that use the cruise control a lot, drive resonable speeds, and get 6-7 MPG everywhere they go. You also have those who drive flat foot to the floor everywhere they go and try to get around 4.5 MPG (that hurts) For you company fellas out there the difference between 5MPG and 6MPG on a 2800 mile week is somewhere around $600 in fuel, that blows all the tractors profits right out the stacks.

Anyhow here are a few of the least expensive options we have found, there is the Vortex Cyclone which is a metal apparatus that you house inside your air inlet sleeve comming off the turbo, this cost about $70, it's supposed to twist the air as it goes into the intake manifold causing higher fuel burn & less emissions. "A tornado creates much more dammage than a wind storm".

Another we've found is the Turbo 3000D Fuel Saver for around $190, goes in line with the fuel inlet before the injectors to Shrink the rate of fuel down while increasing pressure. This allows less fuel to actually be used, and allsow the large diesel to consume all fuel provided (no waste), all the while your not starving the engine nor loosing any horsepower. This particular company proposes around a 10% savings in fuel consumption.

Finally we've explored the option of replacing the belt driven engine fan with an electric engine fan, the kit for a Detroit Series 60 is around $450. Of course with simple mechanics I would expect some increase in horsepower and fuel milage since there is less drag on the engine itself.

Has anyone used these techniques? If so I would be very interested in hearing your feedback on these options. Also if there are any other GOOD options (reasonably priced) to be considered I'd like to hear your input on that as well.
