The first posting in this category is from Dr. Kim Mitchell of California. This is a case I will be following most closely as Californians are dealing with the highest priced, the highest taxed and the worst, most polluted fuel in the nation.
He begins:
Objective: Demonstrate improved mpg and reduced wear/friction losses on my 2003 Toyota Camry XLE 3.0L V6 using the various Snake Oil Products (odometer 172522 miles).
Background: I have great respect for Ron Hatton and the Gadgetman Groove Forum - thumbs up to everyone - we can reduce the energy footprint of transportation through enhanced mpg. I have been involved in global energy issues my entire career - global pioneer in photovoltaics, energy conservation, etc. Around 2004, since I did not like the normal 22 mpg for my car, I redesigned the air intake to reduce the air restriction and achieved 42 mpg over a 55 mile stop-and-go distance (Fairfax, CA to San Ramon, CA) - I was shocked that the air intake for the 3.0L V6 was identical to the air take for the 2.4L 4 cylinder Camry. The ECU did not like my changes and reduced my results. Toyota would not work with me. During that time, in attempting further mpg improvements, I damaged one of the oxygen sensors (expensive replacement) and stopped further experiments. Note: I also found the tire to road friction loss is primary #1 - in addition, on hwy 680 (East San Francisco Bay Area) I found 2-3 mpg different in road surface (concrete vs asphalt); tire pressure (higher is better - for my tires, 32 psi).
Currently I work out of my home so most driving is local. The XLE has a built-in instantaneous mpg and average mpg display. From physics, F=ma (force = mass x acceleration). In theory, if speed is constant, acceleration is zero and the required energy from engine is zero. Thus, most energy is consumed in acceleration (stop to driving speed, eg. 25 mpg), as verified by my mpg gauge. Unfortunately, in reality, at constant speed, the primary loss is overcoming friction (#1: tire to road contact; #2 drive train/transmission losses, etc...). That is why the dealers show the average mpg lower than the highway mpg.
Current Study: I added the Snake Oil coolant and power steering additives on 18 Oct 2019 (odometer 172522). The next day, filling my gas tank, I added the transmission fluid additive and 5cc of fuel additive (odometer 172524). My prior full tank refill around-the-town results were 16.9 mpg (at average 21.7 mph). So far, today (around-the-town), after 24.2 miles, my average mpg is 19.8 (a 17 % increase).
My recent benchmark for freeway driving (yet untested with the Snake Oil) is 26.6 mpg (at 61.3 mph) over 320.9 miles. In the past, I have had around 35 mpg highway which has gone down over time. Although I regularly change oil, I have not done an engine tune-up since around 100,000 miles (bad experience with auto shop).
I will keep everyone updated.
Life is a miracle,
Blessings,
Kim
