How to Change Your Own Oil: Complete Guide

An oil change at a shop runs $50-100 in 2026 for conventional oil and $75-150 for full synthetic. The same job takes under 30 minutes in your driveway and costs $25-45 in materials. More importantly, doing it yourself means you choose the exact oil and filter your engine needs rather than whatever a quick-lube franchise keeps in bulk. This guide walks through the entire process from start to cleanup.


What You Need

Materials

ItemCost RangeNotes
Engine oil (correct weight and quantity)$20-35Check owner’s manual for weight (e.g., 5W-30) and capacity
Oil filter$5-12Match by part number for your year/make/model
Drain plug washer$0.50-2Copper or aluminum crush washer; replace every time

Tools

  • Floor jack and two jack stands (or ramps)
  • Socket set or box-end wrench (for drain plug)
  • Oil filter wrench (strap-style or cap-style)
  • Drain pan (5-quart minimum)
  • Funnel
  • Rags or paper towels
  • Nitrile gloves
  • Wheel chocks

Step-by-Step Oil Change

Step 1: Prepare the Vehicle

Park on a flat, level surface. Engage the parking brake and place wheel chocks behind the rear tires. Run the engine for 3-5 minutes to warm the oil; warm oil flows faster and carries more contaminants out with it. Turn the engine off.

Step 2: Raise the Vehicle Safely

Position the floor jack under the designated jack point (consult your owner’s manual) and raise the front of the vehicle. Place jack stands under the frame rails and lower the vehicle onto the stands. Give the car a firm push to confirm stability before getting underneath. Never work under a vehicle supported only by a jack.

For additional lifting techniques, see our article on how to raise a car without a jack or stand.

Step 3: Drain the Old Oil

Locate the oil drain plug on the bottom of the oil pan. Place the drain pan directly beneath it. Using the correct socket or wrench, loosen the plug counterclockwise. As the plug comes free, angle it downward so oil flows into the pan rather than down your arm. Let the oil drain completely; this takes 5-10 minutes.

Inspect the drain plug threads and the crush washer. Replace the washer with a new one, then thread the plug back in hand-tight before snugging with the wrench. Do not overtighten; this strips the oil pan threads and creates an expensive problem.

Step 4: Replace the Oil Filter

The filter location varies by vehicle: top-mounted (cartridge style inside a housing) or bottom-mounted (spin-on canister). For spin-on filters, use a filter wrench to turn counterclockwise. Before installing the new filter, apply a thin film of fresh oil to the rubber gasket ring. This prevents the gasket from sticking and tearing during the next removal. Thread the new filter on by hand until the gasket contacts the mounting surface, then tighten an additional 3/4 turn by hand only. We cover the cartridge-type replacement in detail at 6 steps to change a cartridge oil filter.

Step 5: Refill With Fresh Oil

Remove the oil filler cap on top of the engine. Insert a funnel and pour the correct amount of oil specified in your manual. Pour slowly to avoid overflow. For clean pouring techniques, see our guide on 4 ways to make an engine oil funnel.

Step 6: Check the Oil Level

Replace the filler cap. Start the engine and let it idle for 60 seconds; watch the dashboard oil pressure light, which should extinguish within a few seconds. Shut off the engine, wait 2-3 minutes for oil to settle, then pull the dipstick, wipe it clean, reinsert fully, and pull again. The level should read between the MIN and MAX marks. Add oil in small increments if needed. For dipstick reading technique, see our best method to read an oil dipstick accurately.

Step 7: Check for Leaks

With the engine off, look under the vehicle at the drain plug and filter for drips. Tighten slightly if you see seepage, but do not force either component.

Step 8: Lower the Vehicle and Clean Up

Raise the vehicle off the jack stands, remove the stands, and lower the car to the ground. Transfer used oil from the drain pan into the old oil containers and take them to any auto parts store or municipal recycling center for free disposal. Never pour used oil down a drain, onto the ground, or into household trash.


How Often Should You Change Your Oil?

Modern full-synthetic oils in 2026 models last 7,500-10,000 miles under normal driving conditions. However, several factors shorten the interval:

  • Stop-and-go traffic or short trips under 10 miles — oil does not reach full operating temperature, allowing moisture and fuel to accumulate
  • Towing or heavy loads — increased engine stress breaks down oil faster
  • Dusty or extreme-temperature environments — contaminants enter faster
  • Older engines with higher mileage — worn seals and looser tolerances increase oil consumption

Conventional oil should still be changed every 3,000-5,000 miles. Always follow the interval in your owner’s manual rather than generic advice. For a complete schedule of all maintenance tasks, see our car maintenance checklist.


Common Mistakes to Avoid

  1. Wrong oil weight — Using 5W-20 when your engine calls for 0W-20 affects fuel economy and engine protection
  2. Overtightening the drain plug — Snug plus 1/4 turn is enough; stripped threads mean a new oil pan
  3. Forgetting the crush washer — Reusing a compressed washer causes slow leaks
  4. Double-gasketing the filter — Always verify the old filter gasket came off with the old filter; a stuck gasket means two gaskets stacked, which blows out under pressure
  5. Not pre-oiling the new filter gasket — A dry gasket can fold, tear, or bind during installation

Key Takeaways

  • A DIY oil change costs $25-45 in materials versus $50-150 at a shop
  • The entire process takes under 30 minutes once you have done it twice
  • Always use the oil weight, filter part number, and drain plug torque specified in your owner’s manual
  • Replace the drain plug crush washer every time
  • Dispose of used oil at any auto parts store for free
