Is 55 the answer?

1n73r.net — I drove my car for 1 week as I normally would and 1 week never allowing my engine to rev over 3000 rpm...Not allowing my engine to go over 3000 rpm held me to a top speed of about 57 mph...For me this was approximately a 28% rise in my fuel efficiency. May 11, 2006 View in Crawl 4
