I saw this first in Scientific American December 2008 page 42. so I looked up the original article in Energy & Fuels November 2008
Electrorheology Leads to Efficient Combustion

The typical laboratory test result of the Mercedes-Benz with a dynamometer is shown in Figure 7, At a fixed fuel consumption rate close to 500 g/h, the dynamometer measured the engine output. When the device was turned off, the average power output was 0.3677 hp. It increased to 0.4428 hp after the device was turned on. This indicates that the power output was improved by about 20.4% at the same fuel consumption rate. In other words, if the engine on the road is under the same condition as our laboratory test with the dynamometer, the fuel mileage will be increased by 20.4%. The laboratory test was repeated for 3 h and had an error within 5%.

Figure 7. Laboratory test of Mercede-Benz 300D with a dynamometer. The average power output was originally about 0.368 hp and increased to 0.443 hp after the device was turned on.
A continuous road tests of the Mecedes-Benz 300D for 6 months showed that our device increased the fuel mileage significantly. On the highway, the device increased the fuel mileage from 32 miles per gallon (mpg) to 38 mpg. In city driving, the improvement of fuel mileage was not as good as that on the highway but was averaged at 12−15%.
Looks like another good starting place for better mileage
