Cav Update
My last tank of gas lasted 574 miles, which worked out to be 39 mpg. That's 133 miles further than I would normally get. I think I was a bit too aggressive getting up to speed on that tank, so I've been driving "gentler" on this new tank.
I have been noticing more of a gasoline smell around the Cav while it's been running lately and with the Cav rolling past 202,000 miles, its possible there is a problem developing with the engine.
