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.
Re: Low mileage oil change. On the newest car (2010) with about 70K miles on it, I use synthetic oil and change it at about 8K miles, which takes about 7 months as it's our long distance vehicle. The 2004, which my wife drives, is local use only and has right at 20K miles. It gets regular oil and is changed once a year at inspection time.
