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.
What kind of oil do you use in a 2004 Hyundai elantra? Hyundai recommends that you use: SAE 10w30 above â9 degrees F SAE 20w50 above 32 degrees F SAE 5w30 below 95 degrees F If it were my car I would use SAE 5w30 year round â¦ and you are well protected. 2001 Hyundai Elantra takes 10W 30 oil. The Hyundai will take  approximately 4.2 quarts of oil. The oil can be purchased at any  auto parts store.
