How to Change Engine Oil and Filter on 120 Toyota Prado
If you own a Toyota 120 Prado, you probably already know it’s a solid, reliable rig that loves long drives, rugged tracks, and everything in between. But to keep your Prado purring like a legend, regular maintenance is key—especially oil changes.
In this guide, I’ll walk you through how to change the engine oil and oil filter on a 120 Series Toyota Prado. Whether you're prepping for an off-road adventure or just keeping things tidy under the bonnet, this is one of the simplest yet most important bits of maintenance you can do yourself.
What You’ll Need:
Engine oil (Toyota recommends 10W-30 or 15W-40 depending on your climate)
New oil filter
Oil filter wrench
Socket set
Drain pan
Funnel
Gloves and rags
Jack and jack stands (optional, for easier access)
Step 1: Warm the Engine Slightly
Let the engine run for a few minutes before starting—this warms the oil, making it flow more freely when you drain it. Don’t get it too hot though, you don’t want to burn yourself.
Step 2: Remove the Drain Plug
Slide your drain pan under the sump (the lowest part of the engine) and use a socket wrench to carefully remove the sump plug. Let the oil drain completely—this might take a few minutes.
Tip: Keep an eye out for the washer on the drain plug. Replace it if it's worn or cracked to prevent future leaks.
Step 3: Remove the Oil Filter
Using an oil filter wrench, twist off the old oil filter. Be prepared for a bit of oil to spill here too, so keep your pan underneath.
Before installing the new filter, dip your finger in some fresh oil and rub a bit around the rubber seal of the new filter. This helps it seat properly and makes it easier to remove next time.
Step 4: Install the New Filter & Refit the Drain Plug
Screw on the new filter by hand until it's snug—don’t over-tighten it. Then, reinstall the drain plug securely (but don’t go full Hulk on it).
Step 5: Add Fresh Oil
Pop the bonnet, remove the oil cap, and pour in your fresh engine oil using a funnel. Your Prado’s engine takes around 8 litres (check your manual to be sure for your engine variant).
After filling, give it a minute and check the dipstick. You want the oil level sitting between the full and low marks.
Step 6: Start the Engine & Check for Leaks
Start the engine and let it idle for a few minutes. Keep an eye under the vehicle to make sure there are no leaks around the filter or drain plug.
Once done, turn it off and recheck your oil level after a few minutes—it might drop slightly once the oil circulates.
Final Thoughts
Changing your own oil not only saves you money—it also gets you better acquainted with your vehicle. Plus, there’s something pretty satisfying about getting your hands dirty and doing your own maintenance.
