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.
If you want 2.4 motor in Sonata to serve you longer, purchase Synthetic 5w30 oil only. During regular service of Sonata take 3.9 liters of engine oil. With average mileage over 100 000 miles youâll find Hyundai Sonata taking a little oil, so buy more than 5.6 liters to add.
