At an average of $1.46 per gallon, Utah's unleaded gasoline prices today are tied with Wyoming as the lowest in the nation. Utah's average is now a full 20 cents lower than the national average, according to travel-services company AAA, which has a state-by-state listing of gas-price averages here. What should consumers do now? Well, think again before going out and buying a gas guzzler. Most experts believe gasoline in Utah and the rest of the nation has reached a low, and that gas prices will rise next year. While $4-a-gallon gas isn't expected, prices along the Wasatch Front could rise back up again to around $2.50 a gallon in 2009. If you're in the market for a new vehicle, this may be the time to look at one that runs on compressed natural gas (CNG). With gas prices this low, there are fewer people looking to buy a CNG vehicle right now, and prices have come down a bit.
