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.
Now for all corolla's up to 2011 the oil change intervals is set by toyota at 5000 miles or 6 months whichever comes first. However the ideal time to replace your oil is 3000 miles or 6 months whichever comes first. If you are using toyota's genuine oil which then it's 5000 miles.If you are using any other brand of oil then the recommended interval is 3000 miles. I would recommend you replace your engine oil at 3000-4000 miles for the longest life of the engine.f your corolla is 2011-2013 year then it will use a full synthetic 0w20 and then the oil change interval by toyota is 10,000 miles or 1 year whichever comes first.
