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.
Answer Wiki. According to the manual, Toyota 2011 Prius Warranty and Maintenance Guide, your 2011 Toyota Prius requires an engine oil and filter change every 10,000 miles, if using 0W-20 synthetic oil, or every 5,000 miles if using anything else. If I were interested in keeping my warranty in force, I would stick with the manual's recommendations.
