If you own a 5th Generation Toyota 4Runner, you already know it’s a rugged and reliable vehicle built to withstand tough conditions. Yet to keep it running smoothly, a routine 5th gen 4Runner oil change is one of the most important maintenance tasks you can perform. Changing your oil regularly keeps the engine lubricated and ensures a longer lifespan for your 4Runner.
Many owners wonder what the 5th gen 4Runner oil change interval should be. While Toyota generally recommends changing the oil around 10,000 miles if you use synthetic, many enthusiasts prefer a shorter interval of about 5,000–7,000 miles for extra peace of mind. In this guide, you’ll get specific instructions on how to carry out an oil change 5th gen 4Runner quickly and efficiently.
This article answers several common questions: How do you remove the old oil without creating a mess? How do you drain and replace the oil filter? And how do you reset the maintenance reminder?

A 4Runner 5th gen oil change is simpler when you have the right set of tools and supplies on hand. Make sure you gather the following:
- 6.6 quarts of 0W-20 full synthetic oil
- Toyota OEM or TRD oil filter (cartridge type)
- Funnel
- New oil drain plug gasket (crush washer)
- 10mm, 12mm, and 14mm sockets (plus ratchet)
- 3/8-inch drive extension for the filter housing
- 64mm oil filter wrench (for cartridge filters)
- Torque wrench (to confirm 5th gen 4Runner oil change torque specs)
- Latex or nitrile gloves
- Drain pan (large enough for about 7 quarts)
- Rags or paper towels
It’s also wise to have a copy of your owner’s manual. You’ll verify the correct oil capacity, recommended oil type, and reference torque values.

Below are the step-by-step instructions that will guide you through the entire oil change 4Runner 5th gen process, from preparation to cleanup.
Step 1 – Prepare Your Vehicle
Choose a flat, level surface. Engage the parking brake and ensure the engine is turned off. Hot oil drains faster, so it helps if the engine is warm, but not so hot that you burn yourself. Lay out all the tools and supplies listed above. Doing so keeps everything close at hand and prevents interruptions once you begin. Locate the oil filler cap on top of the engine. Remove it and set it aside. This allows air to flow through the crankcase and helps the old oil drain more easily.
Step 2 – Drain the Old Oil
Beneath the engine, you’ll find a small access panel (secured by a couple of bolts) if your 4Runner has stock skid plates. Remove this panel with a socket to access the drain plug. Slide your drain pan underneath the drain plug. Make sure it’s centered so it can catch all the oil. Using a 14mm socket, turn the bolt counterclockwise. Be careful, the oil might be hot.
Remove the bolt by hand once loose and let the oil flow into the pan. Wipe the drain plug with a clean rag. Inspect the threads for damage. Replace the old gasket with a new one. Once the oil flow reduces to a drip, reinstall the drain plug with the new gasket. Tighten it to the recommended 5th gen 4Runner oil change torque specs (about 30 ft-lb, but verify in your manual).
Step 3 – Replace the Oil Filter
If you have a front skid plate, remove the bolts (usually 10mm or 12mm) and tilt the plate down. Carefully unhook it from the hinge brackets. Place it aside. On the bottom of the filter housing, there’s a small metal plug. Use a 3/8-inch drive to twist it out. A small amount of oil might drip.
Your new Toyota filter usually comes with a small plastic drain tool. Push this tool into the open filter drain port. Oil will begin to flow out. Once it finishes, remove the plastic tool and discard it along with the small O-ring that often comes off with it.
Attach a 64mm oil filter wrench to your ratchet. Turn the entire filter housing counterclockwise. You may need consistent force as it can remain snug until fully loosened. Pull out the old cartridge filter and discard it. Locate the large O-ring around the filter housing and remove it. Coat your new O-ring with fresh oil, then slide it into the correct groove. Install the new cartridge filter.
Thread the housing back onto the engine by hand. Tighten it firmly but do not overtighten. Most owners use about 18 ft-lb on the housing itself and about 10 ft-lb on the small housing drain plug.
Step 4 – Add New Oil
Return to the top of your engine compartment. Place a funnel into the oil filler opening. Pour in roughly 6.6 quarts. To avoid spills, pour slowly. Keep track so you don’t exceed the recommended capacity. Wait a minute, then check underneath. Look for any sign of oil dripping from the drain plug or filter housing. If you spot leaks, tighten the components slightly more, but do not exceed recommended torque.
Step 5 – Check Oil Levels and Clean Up
Turn your ignition to start the engine. Let it idle for about 30 seconds, then turn it off. This circulates the oil and fills the new filter cartridge. Remove the dipstick, wipe it clean, then reinsert it fully. Remove it again and check the oil level. If it’s below the full mark, add small increments of oil.
If everything looks good, put your skid plate back on. Tighten all bolts to 21 ft-lb if not otherwise specified. Replace the smaller access panel if your 4Runner has one. Transfer old oil to a sealed container and take it to a recycling center. Never pour used oil down a drain or into the trash. Wipe away any spills under the hood or on your tools. This helps you spot future leaks more easily.
Common Mistakes to Avoid

- Over-tightening the drain plug: Excessive torque can strip threads or crush the gasket. Always follow the recommended torque to avoid damage.
- Using the wrong oil type: Toyota specifies 0W-20 synthetic for the 1GR-FE engine. Using a higher viscosity can reduce fuel economy and cause engine wear.
- Forgetting to reset the oil change light: After each 4Runner oil change 5th gen, remember to reset the maintenance reminder. Turn the ignition to “Accessory” mode, set your display to trip meter A, turn the ignition off, press and hold the trip reset button, then turn the ignition back on. Continue to hold until the display indicates the reset is complete.
