What was the average MPG rating in 1975?

Vehicle efficiency increased steadily throughout the early 1980s as the fuel economy law of 1975 was phased in. Between 1975 and 1985, average passenger vehicle mileage doubled from about 13.5 mpg to 27.5, while fuel economy for light trucks increased from 11.6 mpg to 19.5.

What mods increase MPG?

Install These 4 Aftermarket Parts to Improve Your Gas Mileage

  • High-Flow Cold Air Intake System. One of the first aftermarket parts you should consider when you’re aiming for better gas mileage is an air intake system.
  • Cat-Back Exhaust System.
  • Performance Chip or Tuner.
  • Performance Suspension Kits.

Do CAFE standards apply to trucks?

NHTSA’s Corporate Average Fuel Economy (CAFE) standards regulate how far our vehicles must travel on a gallon of fuel. NHTSA sets CAFE standards for passenger cars and for light trucks (collectively, light-duty vehicles), and separately sets fuel consumption standards for medium- and heavy-duty trucks and engines.

How do I figure out mpg?

Take the number of miles that elapsed between tank fills, and divide that by the number of gallons it took to refill your tank. The number you get is how many miles per gallon you are yielding. To simplify, the formula is: miles driven รท gallons used = mpg.

How can I get better gas mileage in my older truck?

10 Ways to Maximize Fuel Efficiency in Older Trucks

  1. Overcompensate on oil changes.
  2. Upgrade to a high-flow exhaust system and high-flow air filter.
  3. Monitor your spark plugs.
  4. Buy the right tires and check tire pressure often.
  5. Add helper springs.
  6. Firm up the shifts and check the gear ratio.

Why are American cars so fuel inefficient?

The reason why American cars on average are fuel hungry, is because the cars that Americans buy are big and heavy, and equipped with big V6 and V8 engines. Compare a pickup truck with a small sedan.

Are standards more fuel efficient?

The CAFE standard was instrumental in more than doubling the fuel economy level for US cars from 1973 to 1988, from an average of 14.2 mpg to 28.6 mpg respectively (DeCiccio, 1995). But only modest increases in fuel economy have been achieved since then, e.g., 32.6 mpg in 2009 (US Department of Transportation, 2009).
