2011-06-03 241.2 5.28 $3.76 45.68 "This reflects windshield wiper delete, and folded mirrors. All highway miles."
2011-06-07 258.6 6.292 $3.76 41.1 "Performed an O2 sensor wrap with aluminum foil and extracted ozone from the distributor cap. MPG is down...prob from a little bit of city driving."
2011-06-09 244.6 5.82 $3.84 42.03 "This is a transition fill up. I am moving to a different gas station...the only one in our town that does NOT add 10% ethanol. The price is a little higher and it is 5 miles outside of town."
2011-06-10 125 2.71 $3.84 46.13 "This is more like it! Perhaps the better fuel plus the ozone mod is helping some. My driving habits have remained steady. Soon, I'll be playing around with some aero mods like a grill block and side mirror delete. HHO is coming soon....."
2011-06-14 260 5.77 $3.84 45.06 "I completed my side mirrors delete, grounded the exhaust, and installed the HCS (Hydrocarbon Cracking System). I'll give it another 2 fillups to see if it made a difference. BTW, in case anyone is wondering about my low mileage fillups, I'm only filling up about half a tank. This way, I can check my mileage more often...which is about every two days....since I drive 120 miles a day."
2011-06-16 250 5.12 $3.84 48.83 "The is the first legitimate run using the HCS. I will go another run to see what we come to. In a few days I will be installing a Hydrogen generator."
2011-06-21 425 9.24 $3.74 46 "I have a fuel heater installed, and a hydrogen generator installed, but the generator is not hooked up yet. I have an optimizer but it also is not installed yet."
2011-06-23 250.8 5.24 $3.74 47.86 "Still using a fuel heater, ozone tap from distributor, but the o2 sensors are not enhanced yet. They need to be as I am still dumping 14.7:1 A/F ratio when it could stand to be leaned out. Not a bad mileage number though..."
2011-06-25 130.4 2.98 $3.74 43.76 "One day of travel. I needed to top off before my 390 mile trip from Fallon to Bishop today."
2011-06-25 390 7.95 $3.57 49.06 "Drove to Bishop CA and back today. Not bad for having no sensor adjustments! Soon I'll have an o2 sensor and map sensor adjusters on...."
2011-06-28 255.4 5.33 $3.57 47.92 "I have installed a MAP sensor enhancer. I used it for about 120 miles in this run. I will soon have the Optimizer installed where I can adjust the O2 sensor as well."
2011-07-01 255.8 5.49 $3.57 46.59 "Not as high as I would have hoped. I thought the MAP adjuster would have helped, but this confirms what I've been reading, and that is that you also need an EFIE. Also, I heard that your O2 sensor is the king when it comes to the A/F ratio and cruising mileage. But your MAP sensor is king when you pop into open loop for city driving. I need to stop procrastinating and get this Optimizer installed!!"
2011-07-08 492.8 10.61 $3.57 46.45 "By accident, I had the optimizer turned off during my driving when I thought it was turned on. Next fillup should reflect some sensor mods. Also I'll have HHO going for at least 120 miles...."

2011-08-03 386.2 8.65 $3.7 44.65 "Contained some city driving....about 25 miles worth."
2011-08-08 371.2 7.5 $3.7 49.49 "I think my water injection is kicking in.....and giving me a slight boost?"
2011-08-11 371.2 7.97 $3.7 46.57 "My throttle body must be gummed up because sometimes my gas pedal sticks. This introduced a lot of high idling which burns up extra fuel. Grrr. I will try to take it apart this weekend and clean it good. A new one costs $250! Gag."

2011-08-29 483.1 10.44 $3.66 46.27 "Still without water injection. I'll probably install it soon."
2011-09-14 486.6 10.635 $3.76 45.75 "Installed Front air dam."
2011-09-15 120.8 2.049 $3.76 58.96 "I tried my hand at some hypermiling-controling my speeds and shifting rpms....so I cruised our I-80 going between 50-55mph. The only engine mod I have is a water injection device called the Aquatune.

I did install a new front air dam. So perhaps that helped a bit with aero drag. Nice numbers! Although, this is only for 120 miles...so next time I'll go a full 480mi so see if this is consistent."
2011-09-22 456.6 8.932 $3.6 51.12 "Still trying to drive at low rpms on the highway. Around 50-60mph. I am at 7 cents per mile on this run. Soon I'll be installing MSD rotor and cap, with Pulstar plugs.

I also did partial grill block."

2011-09-30 376.2 7.393 $3.6 50.89 "Car is hard starting....so that is why I replaced the spark plugs to Pulstar Iridium, and added MSD ignition with external coil. Plug wires are the same. Oh, replaced the fuel filter too.

I also removed the Aquatune....it was pulling too much water and the engine didn't like that.

My next mods will be aerodynamic in nature. Anyone know where I can get some 7"" or 9"" deep lawn edging??"

Haven't been this low since I first got the car. Going to install a PCV catch can soon."
