One of the easiest ways to save money when operating a vehicle is through preventative maintenance. Many people are hesitant to do preventative maintenance on their vehicle because why fix it if it isn't broken? The short answer: so that it never breaks. If you can catch or prevent major repairs completely this will save you money on your vehicle. For example, the average cost of an oil change for a mid sized vehicle is 65.00. The average driver drives 20,000 kms per year. Industry standards suggest getting an oil change every 5,000 kms or whatever your owner's manual suggests. This means an average cost of oil changes for a year would be $260.00. So for a monthly cost of $21.00 you are preventing having to replace your engine (or your vehicle) for a cost of $4000-$8000.00. Preventative maintenance when performed when needed can save you a lot of money and prevent a lot of stress.
