They never try and up sales you. A lot of the companies that offer oil change services here. Always find something that want to charge you 100’s if not 1000’s to fix something they “find” GR Auto doesn’t do that and if you need a repair they tell you how much time you have to get it done.

Horsepower: An Estimate of Engines’ Energy

A fine-tuned engine performs at peak capacity, running smoothly and generating more horsepower. Read on to learn more about horsepower and what it means to work.

An engine that packs a lot of horsepower is an engine that is ready to work. The 18th-century engineer James Watt coined the term to help sell steam engines to mills and mining operations. Watt estimated that an average horse, per minute, could perform 33,000 foot-pounds of work—meaning it could pull 330 pounds a total distance of 100 feet. It was just a rough estimate, but Watt’s calculation has endured as an official unit for measuring engines’ work.

The Benefits of Horsepower

The Model T only had 20 horsepower, but modern cars have left Henry Ford’s creation in the dust. Popular cars, like the Camry or CR-V, house engines that provide 150+ horsepower, an ample amount for running errands and towing kids’ wagons behind them. High-performance luxury cars, meanwhile, boast more than 700 horsepower for more powerful acceleration, and trucks that need to carry heavy loads often fall within the 300–400 range.

Bonus Points

  • The unit could have just as easily been _pony_power, since Watt originally calculated that an average mine pony could do 22,000 foot-pounds of work. To arrive at horsepower, he simply increased that number by half.
  • Watt’s work on work was so influential that a fundamental unit of modern science bears his name.
  • Incidentally, the electrical equivalent of one horsepower is 746 watts, or roughly the same energy it takes to totally shred a Van Halen guitar solo.
