Since the 1950s, the popular calculation of how old a dog was âin human yearsâ has been that 1 dog year is the equivalent of 7 human ones. Even though this formula has been around for a surprisingly long time, the reality is not so cut-and-dried. That doesnât stop many people from defaulting to this traditional calculation.
Oil Changes. I have a 2006 Hyundai Sonata with 56,000 miles on it. The owners manual says to change the oil every 7500 miles. The place I take the car to for the oil change says every 3000 miles. Friends of mine say every 3000 miles because it is mainly driven in the city.
The gasoline engine for the Sonata Hybrid is a 2.0-liter four-cylinder that uses Gasoline Direct Injection for improved efficiency. According to Hyundai's estimates, it puts out 154 horsepower and 140 lb.-ft. of torque. As for the electric motor it produces about 51 horsepower and 151 lb.-ft. of torque.
