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 3,000 Mile, $64k Question: Mustang Oil Filters. Mustang oil filter and oil change intervals can vary from one car to the next. 2010 Mustangs set the oil change interval at 7,500 miles/6 months (under normal operating conditions); this is another case where your ownerâs manual comes in handy.
