How Much Do You Save by Changing Your Car's Engine Oil at Home?

Changing your car's engine oil at home can be a cost-effective and rewarding task. However, the actual savings depend on various factors such as the type of oil used, the cost of labor at the shop, and whether you have the necessary tools and skills. In this article, we will break down the potential savings and provide a comprehensive analysis of the benefits and considerations of DIY oil changes.

Cost of Oil and Filter

The first step in determining the cost is to decide on the type of oil you will use. Conventional oil typically ranges from $3 to $7 per quart, while synthetic oil can cost between $6 to $15 per quart. Most vehicles require between 5 to 8 quarts of oil. In addition, the oil filter usually costs between $5 and $15. This breaks down to a total cost range of $30 to $70 for a full oil change using conventional oil or $50 to $100 for synthetic oil when accounting for the oil and filter.

Cost at an Auto Shop

While the cost at an auto shop can vary, many shops charge between $30 and $100 for an oil change including the labor and materials. This cost can be significantly higher if premium oil is used or if the shop adds additional services such as a tire check or vehicle inspection. Some shops may also offer packages that bundle services at a discounted rate.

Savings Calculation

Let's compare the cost of changing your oil at home versus taking it to a shop:

DIY Savings

If you opt for conventional oil and the shop charges $50, you can save around $20 by doing it yourself for $30. If you choose synthetic oil and the shop charges $100, you can save around $30 by doing it yourself for $70.

In summary, the potential savings from changing your own oil can typically range from $20 to $50 per oil change. Additionally, doing it yourself may offer the benefit of knowing that the job was done correctly and the satisfaction of maintaining your own vehicle. However, it is important to consider the value of your time and whether you have the necessary tools and skills before deciding to change your oil yourself.

The Hidden Benefits of DIY Oil Changes

Many auto shops engage in what is known as a "loss leader" strategy, where the oil change is offered at a lower price to gain access to customers who will then purchase additional services. Shops often perform safety checks and identify other issues that require repair, thus profiting from the added work. On the other hand, a home oil change can cost a little less because you are not paying a mechanic's hourly rate of $30 to $70.

The cost at a reputable shop can be broken down as follows: A shop typically charges $5 for labor, which includes the mechanic's salary, health insurance, building lease, utilities, and overhead expenses. The cost to you is around $45, while for the shop it is approximately $100. This assumption holds true if all you are getting is an oil change.

Example Calculations

I recently had my dealer perform an oil change, tire rotation, and inspection, which cost $45. Using the same synthetic oil, my truck requires 8 quarts, thus costing $8 per quart. So, the cost of the oil alone would be $64. Additionally, my dealer occasionally offers discounts on brake pads and rotors, which can be cheaper than purchasing them individually.

When it comes to vehicle maintenance, taking care of it yourself can be more cost-effective in the long run. My truck has clocked over 280,000 miles and still maintains the same gas mileage as the first month. Regular maintenance can help prevent costly repairs down the line and ensure that your vehicle runs smoothly. Remember, the true value lies in a balanced approach—saving money on oil changes while also addressing other necessary repairs and maintenance.
