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.
I have a 2002 elantra with 42500 miles on it. I have been good about all of my maintenance, and at 32k miles I got my 30k service done at a dealer. that included some belts, coolant drain (not flush) and a transmission drain (not flush).I had also previously done the chemical clean before on the fuel injection system.he owner manual for my 2011 Elantra says change the oil at 7500 miles or 3750 in severe conditions.. My dealer say that because I live in Minnesota (snow, salt, etc.), Hyundai would automatically consider any driving I do as severe. from a warranty perspective.
