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 301,000 miles on my Hyundai Santa Fe with the original engine and transmission. No major work done on either. But I knew that when I hit the 300K mark, the doors would fall off and the engine oil would all leak out, etc. purchased my Santa Fe new and it now has 298,000+ miles. No problems until the last 50,000 or so. Had to replace altenator, air conditioner conpressor, timing chain, and now having trouble with power steering.
