Ran my 12' Accent 1.6 GDi 200 miles tonight and averaged this awesome mpg. I contribute this to PUP GTL 5W30/LM Mos2, non alcohol 87 octane and Injen Intake w/ drycharger. Speeds on KS Turnpike were between 60mph and 85mph. I'm quite happy. Wish I had dosed si1 in fuel tank prior. I think the cooler outside temps helped.
