I have the 4 cylinder 2.4L Chevy Equinox 1LT. I have had my oil changed at about 5000 miles. I had to replace 1 tire due to running over a nail. Got the factory 17" nitro tire for a replacement. Drove up to Winston Salem, NC last night straight through with it in Eco mode and the cruise control on the entire time. Drove in the middle of the night and hit pretty much no traffic. Made it from Tampa, FL to Rock Hill, SC. 585 miles on a single tank. About 34-35 gallons per mile! About time I finally got the advertised mileage. I'm hoping I get even better on the way back. :thumb:
