Summer Driving - Ease Off the Gas Pedal and Save Money

Energy Commission encourages fuel efficiency

SACRAMENTO - Summer time means vacation and even with today's high gasoline prices, there's no reason to give up that anticipated trip. Getting there should be half the fun - not the expense - of this year's vacation get-away and slowing it down can save you money.

Memorial Day traditionally signals the start of the summer driving season when motorists hit the nation's highways in large numbers, usually causing gasoline demand to increase and prices to jump.

Regular gasoline in California averaged $4.12 for May 23, 2011 more than $1 more per gallon than last year. Nationally, regular gasoline is up, too, averaging $3.84 per gallon. The Energy Commission expects ample gasoline and diesel supplies this summer for travelers, however saving fuel and money always makes good sense.

Fuel-Saving Tips for the Vacation Season

  • Slow down and enjoy the ride - it's a vacation! Leave the Indy 500 to the professionals and ease off the pedal. Fuel economy decreases as speeds go up. Vehicles lose roughly one percent in fuel economy for every mile per hour driven above 55 mph. That means a car that averages 30 mpg at 55 mph could typically get 28.5 mpg at 60 mph, 27 mpg at 65 mph, and 25.5 mpg at 70 mph. (The drop in fuel economy varies for different models and ages of vehicles.)
  • Keep the car tuned up and the filters and engine oil clean. Dirty air and oil filters combined with dirty oil can decrease mileage by 2.5 mpg. Worn spark plugs can decrease mileage by 2 mpg. A non-functioning oxygen sensor can decrease mileage up to 3 mpg.
  • Keep tires properly inflated. Low tire pressure reduces gas mileage and causes increased tread wear. Keep tires properly balanced and aligned to get the best gas mileage.
  • Lighten up that load. Keep the kids and dog but remove unused luggage, bicycle or ski racks, and other extra weight.
  • Use air conditioning prudently. Over-use of a car's air conditioner can drop mileage by 2 mpg.
  • Plan trips in advance. Getting lost or having to back track wastes fuel - and time.
  • Where possible, shop around for the best gasoline prices. Stations across the street from each other can vary in price by 20 cents a gallon or more, and stations near the freeway are often the most expensive. Since all gasoline sold in California meets strict fuel standards, most vehicles do well on any brand. Buying the least expensive fuel rewards station owners that lower their prices and encourages others to do the same. Check out Gas Buddy ( or Fuel Me Up ( to find lowest gas prices.
  • Fill up with regular unleaded gasoline. Approximately 80 percent of today's cars and trucks run just fine on regular. By using regular instead of mid-grade or premium, the savings add up.
