Owning a car doesn’t have to cost you a fortune in expensive service bills every year. You can save about £100 just by changing your car’s oil on your own. You only needs some new oil, an oil filter and a few things that can be found around the house and you’re good to go. Changing your oil once every year or 10,000 miles (whichever is soonest) can significantly increase the life of your engine.
