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.
Petrol vehicles in the 0-2 year car parc travel an average of 10,289 miles between oil changes, while diesel vehicles travel 12,455 miles â 21.1% further. This gap shortens significantly in the 3-4 year car parc, with petrol cars travelling 10,085 miles compared to dieselsâ 10,437 â only 3.5 per cent higher.
