Excellent question! Changing your own oil will pretty much always be worth the effort, as it is much cheaper than having a mechanic change your car’s oil for you. When you change your oil at home, all you have to worry about buying is the oil, rather than both the oil and a costly labor charge.
The only way that we can see changing your own oil to not be worth it is if you use the wrong oil or somehow damage your vehicle’s engine in the process—but both are easy to avoid as long as you use the oil type recommended in your owner’s manual and change your oil at the correct intervals.
Hope this helps clear things up!
