My 98 Honda Accord is getting 35 MPG, about two gallons to get to work and back, so that's what I'm driving right now. I had 500 gallons of ethanol free gas delivered early last year before the price went up. Haven't tapped into it yet. If gas gets much higher I will, hoping the price will go down. Also had 500 gallons of diesel and about 1,000 gallons of propane delivered. It would cost me more than double to have that delivered now.
I have two old school diesels. An 84 Mercedes 300TD and a 97 F-350 Powerstroke. Both have over 300,000 miles on them but they are still healthy. I'm going to experiment burning used filtered motor oil in them, diluted with gas or diesel.
That's my new energy policy, we'll see how it goes.
