How To Change Your Own Oil Step By Step Guide To Saving Money

Changing your own oil is one of the most accessible and cost-effective ways to maintain your vehicle. While modern cars are increasingly complex, the oil change remains a simple procedure that anyone with basic tools and a little patience can master. Not only does it save you $30 to $70 per service, but it also gives you greater control over the quality of the oil and filter used in your engine. Over time, those savings add up—potentially hundreds of dollars annually. Beyond the financial benefits, performing your own oil changes helps you develop a deeper understanding of your vehicle’s health and maintenance needs.

Why DIY Oil Changes Make Financial Sense

Most drivers change their oil every 5,000 to 7,500 miles. At an average cost of $50 per visit, that’s $200 to $400 a year spent at quick-lube shops or dealerships. By switching to a do-it-yourself approach, you can reduce that expense to under $30 per change. The initial investment in tools pays for itself after just two or three changes.

The breakdown is straightforward: a high-quality oil filter costs between $6 and $12, and five quarts of motor oil range from $25 to $40 depending on viscosity and brand. Add in reusable tools like a wrench, funnel, and drain pan, and you’re still spending less than half the price of a professional service.

Tip: Buy motor oil and filters in bulk online during seasonal sales to further reduce long-term costs.

Essential Tools and Materials Checklist

Before starting, gather all necessary tools and supplies. Having everything ready prevents mid-job delays and ensures safety. Here’s what you’ll need:

• Wrench or socket set (size depends on your vehicle’s drain plug)
• Oil filter wrench (strap or cap-style)
• Drip tray or oil drain pan (minimum 6-quart capacity)
• New oil filter (correct model for your car)
• Motor oil (check owner’s manual for type and quantity)
• Funnel (preferably spout-equipped)
• Rubber gloves and safety glasses
• Cardboard or mat to stand on
• Jack and jack stands (if ground clearance is low)
• Shop rags or paper towels

Step-by-Step Guide to Changing Your Oil

Follow this sequence carefully to ensure a clean, safe, and effective oil change. Allow about 30–45 minutes for the entire process, especially if it’s your first time.

1. Warm up the engine: Run your car for 5–10 minutes. Warm oil flows more easily and drains completely.
2. Park on a level surface and turn off the engine: Engage the parking brake and shift into park (or gear, if manual).
3. Lift the vehicle if needed: Use a jack to raise the front end and secure it with jack stands. Never rely solely on a jack.
4. Locate the oil drain plug: Under the engine, find the bolt at the bottom of the oil pan. It’s usually 14mm to 17mm in size.
5. Position the drain pan: Slide it directly beneath the plug to catch all old oil.
6. Remove the drain plug: Use a wrench to loosen it slowly. Once loose, unscrew by hand to avoid dropping it into the pan.
7. Drain the oil completely: Let it flow for 5–10 minutes. Inspect the plug for metal shavings—small amounts may be normal; large chunks suggest engine wear.
8. Replace the drain plug washer: Many plugs have a crush washer that should be replaced each time to prevent leaks.
9. Reinstall the drain plug: Hand-tighten first, then use the wrench to snug it—do not overtighten.
10. Remove the old oil filter: Place the pan underneath, then use the filter wrench to loosen it. Turn counterclockwise.
11. Prepare the new filter: Lightly coat the rubber gasket with fresh oil to ensure a proper seal.
12. Screw on the new filter: Hand-tighten only. Most manufacturers recommend no more than ¾ turn past contact.
13. Add new oil: Remove the oil filler cap on top of the engine. Insert a funnel and pour in the recommended amount.
14. Check the oil level: Use the dipstick to verify the level is within the “min” and “max” marks. Add more if needed.
15. Start the engine: Let it run for 30 seconds while checking underneath for leaks at the drain plug and filter.
16. Turn off and recheck oil: Wait a minute, then check the dipstick again. Top off if necessary.
17. Dispose of old oil properly: Transfer used oil to a sealed container and take it to an auto parts store or recycling center.

Tip: Always double-check your oil level after starting the engine. Filters absorb oil during priming, which can lower the level.

Common Mistakes and How to Avoid Them

Even experienced DIYers make errors. These common pitfalls can lead to leaks, engine damage, or messy cleanup.

Mistake	Consequence	How to Prevent
Overtightening the drain plug	Stripped threads, costly repairs	Tighten snugly but never force beyond resistance
Forgetting to replace the crush washer	Oil leak from pan	Always inspect and replace the washer with each change
Not pre-filling the new oil filter	Delayed oil pressure at startup	Fill filter halfway with oil before installing
Using the wrong oil viscosity	Poor lubrication, reduced fuel economy	Consult owner’s manual for correct grade (e.g., 5W-30)
Improper disposal of used oil	Environmental harm, legal penalties	Recycle at certified centers—never dump or trash

Real Example: Sarah’s First Oil Change

Sarah, a 32-year-old teacher from Portland, had always relied on her local mechanic for oil changes. After noticing a $62 invoice, she decided to try it herself. She watched a few YouTube tutorials, bought a $45 tool kit, and sourced OEM-grade oil and filter online. Her first attempt took nearly an hour—she forgot to warm the engine and spilled some oil when removing the filter. But she completed the job safely, disposed of the waste responsibly, and saved $37. Now, she changes her oil every six months and teaches friends how to do the same. “It felt empowering,” she said. “I’m not just saving money—I know exactly what goes into my car.”

Choosing the Right Oil and Filter

Not all oils are created equal. Using the wrong type can reduce engine life and performance. Always refer to your owner’s manual for specifications. Key considerations include:

• Viscosity rating: Indicates oil thickness (e.g., 5W-20). Lower numbers flow better in cold weather.
• Synthetic vs. conventional: Synthetic oil lasts longer, performs better in extreme temperatures, and protects engines more effectively.
• API certification: Look for the American Petroleum Institute “donut” symbol on the bottle.
• Filter quality: OEM or reputable aftermarket brands (like Bosch, WIX, or FRAM) offer better filtration than bargain options.

If you drive in extreme conditions—frequent short trips, towing, or hot climates—synthetic oil is strongly recommended. It may cost more upfront but extends intervals between changes and reduces engine wear.

Frequently Asked Questions

How often should I change my oil?

Modern vehicles typically require oil changes every 5,000 to 7,500 miles. If using full synthetic oil, intervals can extend to 10,000 miles. Always follow your manufacturer’s recommendation found in the owner’s manual or maintenance schedule.

Can I reuse the oil drain plug or filter?

No. The drain plug’s crush washer should be replaced every time to prevent leaks. The oil filter is a single-use component—reusing it risks clogging and poor engine protection.

What should I do with used oil and filters?

Used motor oil can be recycled indefinitely. Pour it into a clean, sealed container and take it to an auto parts store (like AutoZone or O’Reilly Auto Parts), which accepts it for free. Used filters can often be recycled alongside the oil—check with your local center.

Maximizing Long-Term Savings and Vehicle Health

Once you’ve mastered the oil change, consider expanding your DIY skills to air filter replacements, cabin filter swaps, or wiper blade updates. Each small task adds up in savings and confidence. Keep a log of every oil change—date, mileage, oil type, and filter brand—to track patterns and detect issues early.

Additionally, buying oil and filters in multipacks during Black Friday or Amazon Prime Day can cut costs by 20–30%. Some drivers even join warehouse clubs like Costco, where premium synthetic oil is sold at significant discounts.

Tip: Label your oil storage container with the date and type to avoid confusion during future changes.

Conclusion: Take Control of Your Car’s Maintenance

Changing your own oil isn’t just about cutting costs—it’s about reclaiming control over one of your biggest monthly expenses. With minimal tools, a bit of time, and attention to detail, you can keep your engine running smoothly for years. The knowledge you gain builds confidence, reduces reliance on service centers, and fosters a deeper connection with your vehicle. Whether you’re a student, parent, or retiree, this simple skill delivers lasting financial and practical benefits.
