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.
That's the trusted automotive source chiming in with what we already know - the Optima is value-packed, spacious and brimming with family-friendly features. If you want your car to save you money at the gas pump, the 2016 Hyundai Sonata base models will get you 25 miles per gallon in the city and 38 mpg on the highway.
