The runner is costing me about $55-$60 to fill, and my truck is around $95-$110 to fill. Really sucks. I still use my truck to cummute to work though........It's getting about 5 mpg better than the 4-runner. That and people are less prone to cutting me off in my truck during morning rush hour. Funny story, I was cut off by a yuppie in a lexus the other day on the way home. So at the next stop in traffic I ended up right along side him. It was a nice day and our windows were down, so I put the beast in nuetral, cranked up the tuner, and belched a big old cloud of black smoke out of my tailpipe. When he went by me again, I could actually see diesel soot on the side of his white car! I loved it!
