Pleasantly surprised
I've only had my '08 for a week now (all stock, w/ roof bars and General Grabber AT2 tires) - but i've been very pleased with the highway mileage. So far getting about 20 MPG average if most of the trip is highway (cruise at 70) with some stop and go. Took a 90 mile trip out and back up to the mountains yesterday and had my average up to 21.3 by the end of the trip. I have definitely been driving like I want good fuel economy though. I crawl to a start after every light, which may or may not drive other drivers crazy. I've rarely let the rpm's get above 2k. I also plan ahead for stopping, if I'm going to hit a red light, I start coasting as far back as possible, which means I either use less gas before having to stop or I maintain momentum to get back up to speed if the light changes. Around town trips have been more around 15, occasionally up to 17 if I'm really careful. This vehicle is not designed for racing, it's designed for patiently enjoying the ride, whether that's going 70 on the highway or crawling along a rough trail at 5 MPH. Ultimately if you drive like you want it, and your engine is functioning properly, you should get relatively good fuel economy. Enjoy the journey!
