Mine is getting better each fill up during the first 1500 miles. Not there yet where I expect it to be. Second fill was just over 37+ mpg average (don't count the first since that is ridiculously low during break-in). Third was 40+ mpg ave. Fourth fill was 43+ mpg ave. I've been seeing instant readings now around 50-55 mpg or higher at steady speeds on level road regardless the speed (65 down to 35 mph even). I find these readings with keeping the rpms at or below 2500 where possible. Of course in 5th gear 55 mph is at about 3050 rpm, 60 at 3250 rpm, 65 at 3550, 70 at 3950 rpm. MPG only drops below 50 mpg at over 65 mph or if going slightly uphill at speed. Like I said, each fill is still getting better. I expect it to level out at at least over 1500 miles on the clock. Just over 920 miles now.
BTW- you are not the only tightwad. Only I say I'm cheap. Actually it's low cost quality?
