"Although I’m not a mechanic by any means, I’ve found over the last 14 years that a mileage booster called the Condensator, which I installed myself, continues to be very beneficial. Described as a "supplementary carburetor," it was invented by Elmer Bush, formerly of California. Bush, 76, now resides in Noxon, Montana, operates a rural manufacturing business and says his unit has found its way onto some 250,000 engines worldwide since the late 1970s.

An aftermarket addition to any gas, diesel, propane, or natural-gas truck or car, the Condensator captures heavy waste hydrocarbons that normally exit the positive crankcase ventilation (PCV) valve on their way back to the intake manifold. The device first redirects the pollutants through a clear plastic jar to be scrubbed in a container of catalytic BB-sized silica beads. Cooler air in the jar meets the hot hydrocarbons, thereby causing condensation of the particulates into a brownish sludge. Lighter volatile fumes then return to the engine through the base of the carburetor or throttle body.

Mileage and performance can increase up to 30 percent while emissions may decrease by 60 percent. The California Air Resources Board-approved Condensator is a do-it-yourself item that’ll set you back $199 Canadian without shipping, taxes, or installation. (Due to Canada’s currently low exchange rate, U.S. prices are about half this.)

All the maintenance needed is the occasional jar emptying and cleaning, the regularity depending upon the amount of driving and idling. I credit the Condensator for taking my 1981 Buick Skylark to 510,000 kilometers-or more than 316,000 miles. My current 1986 Toyota SR5 4x4 Tercel wagon has gone 239,000 miles and is still climbing."

"Water injection is another process that has boosted performance and mileage for nearly 80 years, including in piston aircraft. I use a simple system in my Toyota during the spring, summer, and fall. I haven’t found it that beneficial in winter conditions, but warmer weather sees me gain up to three miles per gallon with water-vapor injection.

Dr. Guentzler concurs. "Believe me, water injection does work in limiting carbon deposits and enhancing fuel mixture ignitability," he says. "However, anyone mixing alcohol for additional power will increase emissions. Water alone, mixed with fuel, lowers emissions.""

I tested liquid water injection on the same car and saw no increase in mpg. But he mentions "water vapor injection"...which might mean an airbleed thru water?
