Jim, No it doesn't appear to be using any oil. It would have to be a big leak to show up in a weeks worth of driving. Also valves were adjusted about 4 K miles ago and the timing chain was checked for stretch. The mechanic said the stretch was negligible. Hoping that things will improve when I fill up again. This will help sort out the fuel issue
