2013 Ford Expedition Oil Type – The Expert Guide To Protecting
For the 2013 Ford Expedition equipped with the 5.4L V8 engine, the manufacturer specifies 5W-20 motor oil that meets Ford WSS-M2C945-A standards. You will need exactly 7.0 quarts (6.6 liters) of oil and a high-quality filter to ensure your engine’s variable camshaft timing system remains healthy and responsive.
Owning a full-size SUV like the Ford Expedition means you have a vehicle capable of heavy towing, family road trips, and even some light off-roading. However, keeping that massive 5.4L Triton V8 running at peak performance requires more than just a casual glance at the dipstick.
Choosing the correct 2013 ford expedition oil type is the single most important maintenance task you can perform to prevent costly engine repairs down the road. If you have ever heard the dreaded “ticking” sound from a Ford V8, you know how sensitive these engines are to lubrication quality.
In this guide, I will walk you through the technical specifications, the best oil brands for your rig, and the exact steps to perform a professional-grade oil change in your own driveway. Whether you are a weekend DIYer or a seasoned off-roader, this information will help you extend the life of your Expedition.
Understanding the Official 2013 ford expedition oil type
Ford is very specific about what goes into the 5.4L 3-valve engine because the internal components rely on oil pressure for more than just lubrication. The 2013 ford expedition oil type recommended by the factory is 5W-20 premium synthetic blend motor oil.
The “5W” refers to the oil’s viscosity in cold temperatures, ensuring it flows quickly to the top of the engine during a cold start. The “20” represents the viscosity at operating temperature, providing a thin but strong film that reduces internal friction and improves fuel economy.
Using a heavier oil, such as 10W-30 or 20W-50, is generally discouraged for this specific engine. The tight tolerances in the Variable Camshaft Timing (VCT) system require the thinner 5W-20 to move through small passages and operate the cam phasers effectively.
The Importance of Ford Specification WSS-M2C945-A
When you are browsing the aisles of your local auto parts store, look for the Ford specification number on the back of the bottle. This certification ensures the oil has the necessary additives to prevent sludge buildup and resist thermal breakdown under heavy loads.
If you cannot find an oil with that exact code, look for the API “Starburst” symbol, which indicates the oil meets current industry protection standards. Most major brands like Motorcraft, Mobil 1, and Pennzoil will meet or exceed these requirements.
Why the 5.4L Triton V8 is Picky About Viscosity
The 5.4L Triton V8 found in your 2013 Expedition is a “modular” engine design that uses oil pressure to adjust valve timing. This system, known as VCT, allows the engine to be efficient at cruising speeds while still providing power for towing.
If you use an incorrect 2013 ford expedition oil type, such as one that is too thick, the oil may not reach the cam phasers quickly enough. This can lead to a “phaser knock” or even a “check engine” light related to timing over-retarded or over-advanced codes.
Furthermore, the 3-valve heads on this engine have small oil galleys that can easily become clogged if the oil is not changed regularly or if the wrong weight is used. Keeping the oil fresh and thin (5W-20) is your best defense against these common mechanical issues.
Dealing with High Mileage Vehicles
If your Expedition has crossed the 100,000 or 150,000-mile mark, you might be tempted to switch to a thicker oil to stop minor leaks. Instead of changing the viscosity, consider using a High Mileage 5W-20 oil.
These specialized oils contain seal conditioners that help swell old gaskets and O-rings, potentially stopping small drips without compromising the flow needed for the VCT system. It is a much safer alternative than moving to a 10W-30 weight.
Synthetic vs. Synthetic Blend: Which Should You Choose?
From the factory, your Expedition was likely filled with Motorcraft Synthetic Blend oil. This is a high-quality product that offers a balance between the affordability of conventional oil and the protection of full synthetic.
However, many enthusiasts and professional mechanics recommend upgrading to a Full Synthetic 5W-20. Full synthetics offer superior stability at high temperatures, which is a major benefit if you frequently tow a boat or a travel trailer through mountain passes.
Synthetic oil also resists “shearing” better than blends. Shearing is when the molecular structure of the oil breaks down under pressure, causing it to lose its protective properties before your next scheduled oil change.
Benefits of Full Synthetic for Off-Roaders
If you take your Expedition off the beaten path, your engine often runs at higher RPMs with lower airflow through the radiator. This creates extreme heat that can “cook” conventional oil into sludge.
A full synthetic oil can handle these temperature spikes much more effectively. While it costs a few dollars more per quart, the peace of mind during a remote overland trip is well worth the investment.
Essential Tools and Parts for a Successful Oil Change
Before you crawl under your SUV, make sure you have everything you need on hand. There is nothing worse than draining your oil only to realize you don’t have the right filter or enough fresh oil to refill the crankcase.
- 7 Quarts of 5W-20 Oil: Ensure it meets the 2013 ford expedition oil type standards.
- Oil Filter: The Motorcraft FL-820-S is the highly recommended OEM choice.
- 16mm Wrench or Socket: For the oil pan drain plug.
- Oil Filter Wrench: The FL-820-S can be stubborn to remove by hand.
- Drain Pan: Must be able to hold at least 8 quarts of fluid.
- Funnel: To prevent spills on your engine cover and exhaust manifold.
- Clean Rags: For wiping the mounting surface and checking the dipstick.
I always recommend using the Motorcraft FL-820-S filter specifically. It features a silicone anti-drainback valve that prevents oil from draining out of the upper engine when it is parked, ensuring instant lubrication upon startup.
Step-by-Step Guide: Changing Your Expedition’s Oil
Changing the oil on a 2013 Ford Expedition is relatively straightforward because the vehicle has high ground clearance. You may not even need to use a jack, though it can provide extra room to work safely.
1. Warm Up the Engine
Start the engine and let it run for about 5 minutes. Warm oil flows much faster and carries more contaminants out of the engine than cold, thick oil. Just be careful, as the exhaust components will be hot.
2. Drain the Old Oil
Locate the drain plug on the bottom of the oil pan. Place your drain pan underneath and use your 16mm wrench to loosen the plug. Once it is loose, unscrew it the rest of the way by hand, keeping pressure against the pan to avoid a mess.
Let the oil drain until it is a very slow drip. While it drains, inspect the rubber gasket on the drain plug. If it looks cracked or flattened, replace the plug or the gasket to prevent future leaks.
3. Replace the Oil Filter
The oil filter on the 5.4L is located near the front of the engine on the driver’s side. Position your drain pan under the filter, as oil will spill out once you loosen it. Use your filter wrench to break it loose, then spin it off by hand. Pro Tip: Before installing the new filter, take a finger and smear a small amount of fresh oil onto the new filter’s rubber gasket. This ensures a proper seal and makes it easier to remove during your next service.
4. Refill with Fresh Oil
Reinstall the drain plug and tighten it to approximately 17-20 lb-ft. Do not over-tighten, as you can strip the threads in the pan. Use your funnel to pour in 7 quarts of the correct 2013 ford expedition oil type.
The Critical Role of the Oil Filter (FL-820-S)
While we focus heavily on the oil itself, the filter is equally important. The 5.4L Triton engine is known for being sensitive to “dry starts,” which is when the engine runs for a few seconds without oil pressure after sitting overnight.
The Motorcraft FL-820-S filter is designed with a specific bypass valve and a silicone anti-drainback valve. Cheaper “white box” filters often use cardboard internals or inferior rubber valves that can fail, leading to that tell-tale startup rattle.
If you are an off-road enthusiast, your filter is also subjected to more vibration and potential debris. Using a heavy-duty filter with a thicker metal canister provides an extra layer of protection against punctures from road or trail debris.
Resetting the Intelligent Oil-Life Monitor
Your 2013 Ford Expedition is equipped with an “Intelligent Oil-Life Monitor” (IOLM). This system doesn’t just count miles; it analyzes your driving habits, idle time, and engine temperatures to calculate when the oil is actually depleted.
After you have finished your oil change, you must reset this system so it can begin tracking the new oil. If you skip this step, your dashboard will continue to nag you with “Change Engine Oil Soon” messages.
- Turn the ignition to the “On” position (do not start the engine).
- Press the SETUP button on the steering wheel or dash until “Oil Life” appears.
- Press and hold the RESET button for two seconds.
- The display should change to “Oil Life Set to 100%.”
If your Expedition has the message center in the instrument cluster, you may need to navigate through the “Settings” and “Vehicle” menus using the directional pad on the steering wheel to find the oil life reset option.
Frequently Asked Questions About 2013 ford expedition oil type
How many quarts of oil does a 2013 Ford Expedition take?
The 2013 Ford Expedition with the 5.4L V8 engine requires 7.0 quarts (6.6 liters) of oil when you are also changing the oil filter. Always check the dipstick after filling to ensure the level is within the crosshatched “safe” zone.
What is the best 2013 ford expedition oil type for towing?
For towing heavy loads, a Full Synthetic 5W-20 is the best choice. It provides better thermal stability and prevents the oil from thinning out too much under the high-heat conditions common when pulling a trailer up long grades.
Can I use 5W-30 instead of 5W-20 in my Expedition?
While 5W-30 won’t immediately destroy your engine, it is not recommended. The 5.4L V8’s variable camshaft timing system is calibrated for the flow characteristics of 5W-20. Using a thicker oil can lead to sluggish timing response and decreased fuel efficiency.
How often should I change the oil in my 2013 Ford Expedition?
Under normal driving conditions, you should follow the Intelligent Oil-Life Monitor, which usually triggers between 7,500 and 10,000 miles. However, if you frequently tow, drive in dusty off-road conditions, or make short trips in freezing weather, I recommend changing it every 5,000 miles.
Does the 2013 Ford Expedition have a 5.4L or 3.5L engine?
The 2013 model year exclusively used the 5.4L Triton V8. Ford did not introduce the 3.5L EcoBoost V6 to the Expedition lineup until the 2015 model year. Ensure you are following the specs for the V8 when purchasing parts.
