Just came back from visiting family on Memorial Day and wanted to experiment on total max. highway mileage. I topped off at the interstate and drove 135.2 miles with cruise set at 61 mph 'cause my slightly larger tires seem to throw the speedometer off by 5 mph....so I should've been traveling 65/66 mph, which seemed right with the traffic in the slow lane.
The VX consumed 5.884 gallons of premium (I have SC) after traveling 135.2 miles. Therefore, drumroll..........I got 22.97 mpg! This is inline with what I got on my trip to a VX meet 2 years ago from PA to Vermont running with cruise on @ 65 mph.
*I also cleaned my K&N cone filter on Friday and let it dry overnight; then re-oiled it on Saturday. She definately felt zippier!
