Re: Avg fuel eco question
Thought about that but 6.1 liters/100 km would be 38 mpg which is unlikely. Also not many other countries use PON (from the mention of 89 that sounds like regular is 87) which also puts him below 4,000 feet. Also imperial gallons would give better MPG, not worse.
So my money would be on a northern US location in a major city, is parked outside, and has a remote starter.
ps if misfiring I wonder if he got some water in the gas from a little used pump.
