Stop / go traffic vs highway crawl.
took a different route for a while. both routes involve severe hill climbing on the return home. the new route was a lot of stop start city like traffic. it is about 2 miles shorter than my usual route but after 2 weeks my mpg plummeted! engine revs are lower here but my speed is also lower. going to stick to the usual route which is more like a highway crawl, 2nd 3rd gear stuff!
