For Ten Cents Per Gallon, How Far Would You Drive?

Cheap Gasoline?

How far would you drive to save ten cents per gallon on gasoline? 

An eight cents per gallon savings is definitely hard to find and ten even harder.  If your tank is twenty gallons and half empty, you would save eighty cents to a dollar at fill ups.  Some fuels, even at the same octane rating, are higher grade than others, which means they’ll help keep the inside of your engine cleaner. 

The higher the octane, the higher the price per gallon.  Is it worth paying more for higher octane fuel?  What are the advantages?  Higher octane slows flame propagation (burn time) in the cylinders.  Lower octane fuel explodes, which causes detonation, also known as pinging.  Detonation can cause serious engine damage.  Properly working sensors in computer cars tell the ECU (computer) the timing needs to be retarded before engine damage occurs.  When the timing is retarded, there is less time for the fuel to burn completely, which translates to decreased MPG and less power.  Generally, the gains on MPG from the higher octane fuel are less than the difference in the price.  Some manufacturers recommend higher octane fuel because their vehicles have higher compression ratios.  The higher the compression, the higher the octane needs to be to slow the flame propagation. 

Lower compression ratios mean less power and lower MPG than could be achieved from the same engine with higher compression.  When there is less power available at a certain throttle position setting (TPS in ECU computer language), the more the throttle has to be opened to obtain the same speed and power.  The ideal air to fuel ratio (AFR) is 14.7 to 1.  If the throttle position is increased (opened more), the AFR has to be adjusted or the engine will be too lean, which can cause serious engine damage due to lack of cooling.  The ECU increases the fuel to bring the AFR back into specifications, which lowers fuel economy.  

Sixty to eighty percent of the fuel introduced into the engine is used to cool internal engine parts like valves, pistons, cylinder heads, etc.  If you fool, or try to fool, the sensors into leaning the AFR, you’re reducing the cooling and can do serious damage to the engine.  When you’re cruising, you don’t need as much internal cooling, but when you come to a hill, add more passengers, drive at a higher speed or otherwise increase the drag and rolling resistance, you will overheat internal engine parts if the vehicle runs too lean.  Think of it like the difference between sitting and running, or carrying a backpack as opposed to walking with no weight. 

If you save ten cents per gallon and the price per gallon is $4.50, you’re saving 4.5% per gallon.  If you drive more than a few blocks out of the way to save 4.5%, you’re practicing false economy.  If you’re buying a low grade fuel, you’re probably causing excess carbon buildup on the valves and pistons and in the exhaust, and possibly shortening the life of the catalytic convertor, a very expensive item.  The gasoline company ad on TV that shows buildup on valves after 50,000 miles is true.  Carbon buildup lowers engine efficiency, as well as causing hard carbon scoring of the cylinder walls.  But, is it worth paying the extra price? 

Recently I was discussing fuel economy with an engineer, who also has a background in metallurgy and biological molecular science.  According to him, hydrogen molecules are so small they penetrate metal and weaken it.  Unless an engine is specifically made to run on hydrogen, straight hydrogen will cause the engine to fail prematurely.  Hydrogen burns hot and, unless cooling is replaced, overheating of internal engine parts will result.

Hypermiling increases MPG.  Hypermiling is driving with a light foot on the accelerator, not making jackrabbit starts, resisting the urge to accelerate up hills, allowing the vehicle to coast when possible (like down hills and between stoplights), as opposed to charging the first half block, braking the second half and then waiting for the light to change and doing it all over again to the next light.  Going slow, even in the right lane, on the freeway is dangerous.  It’s possible to rechip or flash the ECU to produce a leaner state than the desired 14.7 to 1 and not cause internal engine damage if, and only if, you always hypermile.  But, if you add extra weight, drive faster than usual or need extra power to get into traffic without being run down, you can do damage to the engine. 

So, are we destined to be held hostage by the whims of big corporations, commodity investors and swings in oil prices?  Not really.  You can save from ten to fifty percent with a simple, inexpensive, easy to build and install, alternative.  It’s called water vapor injection and can be seen at www.mileageman1,com.  Properly installed and adjusted, it can increase MPG and power by slowing the flame propagation, the same as buying more expensive fuel.  It can replace expensive fuel used for cooling with much more efficient water vapor.  Water vapor will clean carbon from valves, pistons and the exhaust system, increasing the engine’s efficiency.  You can custom build the system to your requirements with the right information, or you can buy other systems that may or may not fit in the space you have.  Water vapor injection lowers pollution by reducing nitrous oxide and other emissions.  And, as an extra added bonus, water vapor injection will also increase HP. 

  

                 

  

Larry Miller: I was born in Los Angeles in 1940. My father was a fighter pilot instructor during WWll and we moved from coast to coast, maybe that’s where I got the nomad in my blood. After graduating from high school in 1958 I joined the Marines. That lifestyle wasn’t for me and upon my discharge I went on with my life, and have never looked back. I worked briefly for a Caterpillar dealer in Riverside, CA before moving back to N. California where I was a welder and truck driver for a chemical company. Truck driving wasn’t my calling anymore than being in the Marines, and I went back to work for another Caterpillar dealer steam cleaning dirty tractor parts and welding. They sent me to schools, lots and lots of schools. I spent as much time going to trade schools as I did at work. I went from cleaning parts to apprentice field mechanic, to mechanic to the parts department to satellite store manager in less than two years. They wanted me to move to Sacramento and be a salesman: I moved to Oregon to learn to commune with nature. I went to work for another heavy equipment dealer and was later contacted by the World’s largest Lorraine Crane dealer and offered the position of purchasing agent and general parts manager. In 1967 I was offered a line of automotive parts and supplies and went into business for myself. My business revolved around eleven race cars that we maintained for others, driving race cars professionally and maintaining high end sports cars. I was a championship and regional champion driver. My business was the largest import parts and service, non dealer, in the state until I sold it in 1979. We went sailing in 79, first to Mexico and then Hawaii. I was an award winning Trans-Pacific sailor and sailor of the year, Hawaii, Island of Kauai. An opportunity presented itself in Hawaii during 1981 and I was back in business, importing Japanese auto body and hard parts. I also felt the pull to write and began freelancing for magazines and newspapers in 1982. My main focus in my articles is, and always has been, health, wellness and fitness. Most of us have heard the saying, “Time is all we have.” I disagree. Our health is all we have, because without our health, we have no time. I was a US Olympic team hopeful in racewalking and held all the records for the state of Hawaii. As a sponsored athlete in my forties, I finished first in nine marathons in a row in my division, qualified for the Ironman® and was the state USCF cycling champion five times in Hawaii and Oregon. Celinda and I were married in 1988 after a three year engagement. We sold our businesses and organic farm and sailed back to Oregon. After our sailboat boat was sold, we moved to Joseph, Oregon, two miles from the trailhead into the Eagle Cap Wilderness. We were caregivers for my mother the last ten years she was alive. We moved to New Mexico in 1995 because it was too cold for my mom in Oregon during the winters. Celinda designed, and I engineered and built our strawbale house. I began writing the weekly health column for a local newspaper in 1996, and still do. In 2000, I took the summer off to do a four month, 4000 mile, hike, bike and kayak odyssey. I’d been writing health, fitness and sports articles since 1982 and the journey produced a full-length, nonfiction, first person adventure book, Yol Bolsun, May There Be A Road, which can be bought from Amazon.com and others over the Internet. The summer of 2001 was spent hiking. kayaking, fishing and exploring the southwest. In 2002 Celinda and I spent the summer in Canada learning the hospitality business at a resort in preparation for doing promotion for the resort in the US. Most of 2003 was spent reestablishing the trees and landscape that had died during the stay in Canada. We had a house sitter and the house sitter had an ex-husband, and that’s a long story. In July of 2004 I did a solo kayak trip on the Snake River, taking pictures, writing articles and pencil sketching the journey. I hope to do another kayak adventure on the Snake River during the summer of 2008, on the section I missed in 2000 and 2004. In 2005, I returned to Canada to the resort where we’d spent 2002. I was supposed to be there for the month of June. I’d contacted people I’d met in 2002 and they came back to Canada to fish, hike and spend time at the resort, Echo Valley Ranch and Spa, while I was there. My one month became five and then it was off to Spain to do the El Camino de Santiago as a travel companion with one of the guests who’d returned to Canada in June. During the summer of 2006 a friend from Ireland, who I’d met in Spain the year before, came to visit in NM and we fished, hiked and explored the White Mountains of AZ. He’d never slept out in the wild in a tent before, and it was quite an experience, for both of us. My newspaper articles were put on the Internet beginning in 2002. I was asked to give public speaking engagements, photo and video presentations, on various subjects for the library in Deming, NM and continue to do so. In 2006 I videoed and produced a DVD for the Smithsonian Institute’s travel exhibit “Between Fences.” NMFILMS had a conference by invitation only, which I attended. While attending the conference, I realized that film making wasn’t what I wanted to do but I still wanted to use my sixteen years of experience and enjoyment of videoing and photography. During the winter of 2005, I discovered that no one on record had ever run from the Arizona border to the Texas border, a distance of 165 miles. During the spring and summer of 2006 I trained for the run and the run was completed in October, 2006. In late 2005, I began building and maintaining websites incorporating all the things I enjoyed about video, photography, travel and the out of doors. 2007 has been a summer of upgrading the home and property which resulted in a downgrading of my enthusiasm for being located in one place. If we don’t like what’s happening in our life, we need to change what we’re doing. Celinda and I are ready to pull up roots and move on. I guess I’ve come full circle. I’m ready to revert back to my childhood, and a nomadic lifestyle.
