Ethos Fuel Additive
Someone here was wondering about Ethos a few
weeks ago, so I volunteered to do a test in my commuter car. Ethos is an additive that promises a unique approach to improving fuel consumption. The test car is a 1987 Volvo 740 with 2.3L NA gas engine, 160K miles. It has run the same 35 highway mile round trip commute for 10 years, making it a good test candidate. This is cruise control driving with 2 blocks of city driving. Even the fuel-up is constant; same pump every time. Fuel consumption has been constant at just under 26MPG except during the occasional Western Washington snowfall. Because this was a test of Ethos, nothing else was changed on the car before or during the test except engine oil. Ethos recommends adding their product to both oil and fuel. To start the test the recommended amount of Ethos was added to the crankcase along with fresh oil. They also recommend doubling the amount of Ethos in the fuel for the first couple tanks, which was done. The test continued for 5 tanks of fuel, which finished a $28 bottle of Ethos. Fuel consumption ranged from a low of 24.9MPG to a high of 25.5MPG. I could not achieve any improvement in fuel consumption, so Ethos actually resulted in a net increase to driving costs. So much for that. Bob Griesel, WA '84 FC31 WLII '87 Volvo 740 '95 Ford E250 Class 'B' '98 Ford F150 SWB '04 Honda CRV EX AWD |

Ethos Fuel Additive
According to independent test labs,"There is NO fuel additive that
produces statistically valid improvement in fuel economy on a clean, well maintained engine". The study (I think it was Popular Mechanics a few months back) did conclude that you got some improvements with additives that cleaned the carborator or injectors and plugs if the engine was dirty but the benefit leveled off after a few tankfuls. The only fuel economy improvements they consistently saw was: Clean air filter - either cleaned or new - best $ benefit Lower friction fluids - oil, transmission - inexpensive synthetics produced the highest cost/benefit ration, as high as 7-10% Some of the exotic spark plugs produced 1-3% improvements on SOME (but not all) vehicles.

Gary,
Would you remember which issue that article was in?
Thanx

To tell you the truth, I don't even remember the magazine for sure.
It could have been a car magazine. I read it in my doctor's office about 6 months ago +/- 2. His magazines are usually pretty current so Feb. to July 08, maybe. I looked on the Popular Mechanics website and couldn't find a familiar article.

I'll second the motion that Ethos is not worth it. I believe I already posted my Ethos results here a few months back, but I saw a minor increase in mileage in my 08 Accordbut nowhere near the cost of the additive.Homemade bio diesel makes more sense imho.
