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.
City/highway driving is 50-50..... Only about 5000 miles/year. Am seriously considering buying an '07 Sonata. And believe the 4 cyc. should give me enough power. Can anyone give me a good reason why I should really consider the 6 cyc. over the 4. Cost is not a problem.
