Hyper-milers are those people who try to stretch miles per gallon to the limit. Very few people would be interested in doing what’s necessary to get 100 mpg or more when driving their car, but reading some of the standard things that hyper-milers do can help increase anyone’s mileage. Removing excess weight from a car’s trunk, using cruise control for highway driving, keeping tires properly inflated, reducing highway speed, only using air conditioning when necessary, etc. can lower gas consumption considerably when compared to not using their common sense suggestions. Read about hyper-miling on the internet to get a sense of what’s possible. The last time I checked the record-holder was a guy in California who was able to get 167 mpg in his Honda Natural Gas Hybrid!
