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 Optima Plug-in Hybrid borrows the same system used in the Hyundai Sonata Plug-in Hybrid. The Optima slightly beats the Sonata for all-electric range by granting 29 miles of driving without using gasoline. It also shaves a couple of hundred dollars off the Sonataâs sticker price.
