How to Change Your Toyota 4Runner's Oil: A Step-by-Step Guide

What You'll Need Before You Start

Before you begin, gather these items to make the process go smoothly:

• New oil (check your owner's manual for the correct type and amount)
• New oil filter
• Oil drain pan
• Wrench or socket set
• Oil filter wrench
• Jack and jack stands (if needed for under-vehicle access)
• Rags or paper towels
• Funnel
• Newspaper or cardboard (to protect your driveway)

Make sure your 4Runner is parked on level ground and the engine is cool before you start. Working on a cold engine is safer and reduces the risk of burns. If you've been driving recently, wait at least 30 minutes before beginning. Having all your supplies ready in one place will save you time and frustration during the process.

Step 1: Warm Up Your Engine

Start your 4Runner and let it run for a few minutes. Warm oil flows more easily and drains faster than cold oil, which means the process will go quicker. This also helps loosen any sludge that may have built up in the engine.

After a few minutes of running, turn off the engine and wait about five minutes before proceeding. The oil will still be warm enough to flow well, but cool enough that you won't burn yourself when you touch the drain plug or filter.

Step 2: Locate and Remove the Drain Plug

Raise your 4Runner with a jack if you need more space underneath to work comfortably. Make sure the vehicle is secure on jack stands before you get under it. Place your drain pan directly under the oil drain plug, which is located on the bottom of the engine. The drain plug is usually a bolt that sticks out from the engine pan.

Using your wrench, loosen the drain plug by turning it counterclockwise. Once it's loose enough to turn by hand, carefully unscrew it the rest of the way by hand. Be careful—some oil may still be warm and can drip onto your hands or arms. Let the old oil drain completely into the pan. This may take several minutes, so be patient and don't rush this step. You can use this time to prepare your new filter and oil.

Step 3: Replace the Drain Plug

Once the oil has stopped dripping—usually after five to ten minutes—wipe the drain plug clean with a rag or paper towel. Look at the plug's rubber washer. If it looks damaged or worn, you may want to replace it with a new one to prevent leaks.

Screw the plug back in by hand first to avoid cross-threading it. Once it's hand-tight, use your wrench to tighten it a bit more. However, don't over-tighten it—a snug fit is all you need. Over-tightening can damage the plug or the pan and cause leaks later.

Step 4: Remove the Old Oil Filter

Locate your oil filter, which is usually a cylindrical canister on the side of the engine. Use an oil filter wrench to loosen it by turning counterclockwise. Once it's loose enough, unscrew it the rest of the way by hand. Be ready for some oil to spill out—position your drain pan underneath to catch it.

Let any remaining oil drain into your pan. Wipe off any oil residue from the filter mounting surface on the engine with a clean rag. This area should be clean before you install the new filter to ensure a good seal.

Step 5: Install the New Oil Filter

Before installing the new filter, rub a thin layer of new oil around the rubber gasket (the rubber ring) on top of the filter. This helps create a good seal between the filter and the engine and makes it easier to remove the filter next time you change your oil.

Screw the new filter onto the engine by hand until the gasket touches the mounting surface. Once you feel the gasket make contact, turn the filter an additional three-quarter turn (about 270 degrees). This is the correct amount of tightening—not too loose, not too tight. Never use a wrench to tighten the filter, as this can damage it and cause leaks.

Step 6: Add New Oil

Lower your 4Runner back to the ground if you raised it. Make sure the vehicle is stable and level before you proceed. Locate the oil filler cap on top of the engine—it usually has an oil can symbol on it—and remove it by twisting it counterclockwise.

Place a funnel in the opening and pour in the new oil slowly and carefully. Check your owner's manual for the correct amount your 4Runner needs. Most 4Runners require between 5 and 6 quarts, but the exact amount depends on your model year and engine type. Pour the oil in gradually so it doesn't overflow. Once you've added the recommended amount, replace the oil filler cap by twisting it clockwise until it's snug.

Step 7: Check Your Work

Start your engine and let it run for about one minute. This circulates the new oil through the engine and helps the new filter fill with oil. Watch carefully for any leaks around the drain plug and filter area. If you see drips or puddles forming, turn off the engine and tighten the drain plug or filter as needed.

Turn off the engine and wait a few minutes for the oil to settle. Pull out the dipstick, wipe it completely clean with a rag, reinsert it fully into its tube, and then pull it out again to check the oil level. The level should be between the minimum and maximum marks on the stick. If the level is too low, add a bit more oil and recheck. If it's too high, you can remove a small amount with a turkey baster or siphon.

Step 8: Dispose of Old Oil

Never pour old oil down the drain, into the ground, or into the trash. Used oil is harmful to the environment and is illegal to dispose of improperly in most places. Instead, take your old oil to a local recycling center, auto parts store, or service station that accepts used oil for recycling.

Many auto parts stores will take your used oil for free, especially if you buy new oil from them. Some recycling centers also accept it. Call ahead to confirm they accept used oil and find out their hours and any requirements they may have.

When to Change Your Oil

Check your owner's manual for the recommended oil change intervals for your specific 4Runner model and year. Most modern 4Runners need an oil change every 10,000 miles or once a year, whichever comes first. Some newer models with synthetic oil may go longer between changes—up to 15,000 miles or more.

Keeping up with regular oil changes is one of the best things you can do for your 4Runner. Fresh oil helps your engine run smoothly, reduces wear on engine parts, and can extend the life of your vehicle. Mark your calendar or set a phone reminder so you don't forget when your next oil change is due.

Frequently Asked Questions

How often should I change my 4Runner's oil?

Most modern Toyota 4Runners need an oil change every 10,000 miles or once a year, whichever comes first. However, this can vary depending on your model year, engine type, and driving habits. Always check your owner's manual for the specific recommendation for your 4Runner. Driving in extreme conditions—such as towing, frequent short trips, or dusty environments—may require more frequent oil changes.

What type of oil should I use in my 4Runner?

The correct oil type and viscosity (thickness) for your 4Runner depends on your specific model year and engine. Your owner's manual will specify whether you need conventional oil, synthetic oil, or a synthetic blend. It will also tell you the correct viscosity grade, such as 0W-20 or 5W-30. Using the wrong type of oil can affect your engine's performance and longevity, so always follow your manual's recommendations.

Can I change my 4Runner's oil without raising it with a jack?

This depends on your 4Runner's ground clearance and your height. Some people can access the drain plug and filter without raising the vehicle, while others need extra space to work comfortably underneath. If you do use a jack, always use jack stands as well for safety. Never work under a vehicle supported only by a jack, as the jack can fail and cause serious injury or death.

What should I do if I spill oil on my driveway?

If you spill oil, cover it with kitty litter, sand, or other absorbent material to soak it up. Let it sit for several hours or overnight, then sweep it up and dispose of it properly. For larger spills, you may want to contact a local environmental agency or hazardous waste disposal service for guidance on cleanup and disposal.

Is synthetic oil better than conventional oil for my 4Runner?

Synthetic oil lasts longer and provides better protection in extreme temperatures compared to conventional oil. However, it's also more expensive. Your owner's manual will recommend the best type of oil for your 4Runner based on its engine design and intended use. Follow your manual's guidance, and don't feel pressured to use a more expensive oil type than recommended.
