Usually around 50, Use the cruise controll to also help by holding the throttle at a constant place. Humans tend to be in and out of it and uses more fuel

Most vehicles give best fuel economy somewhere between 45 and 55 MPH -- it varies from one to the next. The big rigs get their best economy between 55 and 59 MPH.

I prefer to drive at 48 mph, which gives a good ballance between economy and speed. Driving slower reduces wind resistance, and improves economy.
