sure goto 94 Metro - Home Page click on metrolog and you will see the pics. YOU CAN NOT duplicate that setup however. The ethanol aggressively attacks the plastic. it lasted through about 35 gallons of gas before it leaked all over the place.

I am also concerned about what ELSE I am removing from the gasoline and any water I might be leaving in the gas. the point of the test was to see if it was worth buying $100 in gas cans and making the 90 minutes each way drive and $17 in tolls to go get it.

it confirmed it was worth it. I will still do it for my lawn equipment and motorcycles though. I just do not trust the Ethanol with my small engines.

my first tank of REAL E0 was quite a surprise. it was far far less than ideal. I added 5.7 gallons of E0 and then drove home.

I drove the 125 miles home with 100 pouinds of extra gas in tanks on the 250 pound trailer with a 200-250 pound kenmore washing machine on the trailer that was taller than my car :-) the GPS also burned me (it got reset somehow to AVOID toll roads) so I ended up taking 309 all the way home before I realized what the dumb thing was doing :-) so stop and go traffic 3/4 the way.

then I took the washing machine another 75 miles or so to our warehouse space and then pick up two sheets of 4x8 foot OAK flooring on plywood with beams (free on craigslist) home 50 or so miles.

then drove back up to the mountains and refilled on E0 and my Fuel Economy STILL manages to jump from 46 on E10 to 50.14 on 5.7 gallons of E0 mixed with E10

Thats just a WOW to me.

Higher Compression. Yes and no. it can but usually DOES NOT produce higher FUEL efficiency. in fact the opposite it usually produces higher POWER efficiency but LOWER fuel efficiency.

ie more oomph but but also more slurping.

at the RPM's I run I am not even in the car's power band so PE is irrelevant to me. I keep it at 50mph or so around 1600rpm. optimal power efficiency is over 3000rpm.

As for diesel engines no that is not entirely correct. it is not a combination of higher compression and higher energy.

its just higher energy.

Higher compression is a side effect of the lack of a spark plug and the need to "ignite" the fuel by SQUEEZING it to the ignition point.

IE its the "means" in which a diesel engine runs and has little directly to do with efficiency though it does result in more POWER efficiency (but this hurts Fuel efficiency if you USE this power increase in efficiency)
