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.
Rated 5 out of 5 by JMaCook Dirty Oil Only 2000 Miles Hello Mobil 1, I have a 2003 Nissan Altima 2.5 S and it has 176,700 miles on it. I have kept my car's oil change regularly at 3,000 miles. Recently I decided to switched to synthetic oil and use Mobil 1 High Mileage 5W-30. I have read a lot of good remarks about it. Your support staff recommend that I do a staggered oil change since my car has never used synthetic oil before.
