The traffic jam and stop and go will kill that mileage in a heartbeat.

True, but that's G1 Territory for MPG, Completely unacceptable

Next time you find yourself driving around and there isn't any traffic at all....fill it up. Get on the freeway. Drive 65-70mph for 20 miles or so, turn around and come back to the same pump and top it off.

You do realize he's in Southern California, that rarely happens, like "RARELY EVER"

Ha, no kidding! But I could fill up, hit the very low traffic toll road for a 30 mile round trip and fill up again. If I'm still draining gas like a freight train, that'll do about 2 gallons.

Wasn't sure where in the OC you were, Toll Road would be a perfect for a test. Don't forget to use the same pump and the "click" stop fill method, if possible within an hour or two so the temp stays the same.

Running a GPS would work additionally or supplementally
