The Exact 2018 ford f150 2.7 oil type and Specifications
Ford is very specific about what goes into the 2.7L Nano EcoBoost engine. For the 2018 model year, the manufacturer calls for SAE 5W-30 premium synthetic blend motor oil. This viscosity provides the necessary flow during cold starts while maintaining a strong lubrication film at high operating temperatures.
You must ensure the oil carries the WSS-M2C946-B1 certification (or the newer WSS-M2C961-A1 which supersedes it). These specs are designed to handle the high heat generated by the turbochargers and the specific demands of the timing chain. Using an oil that lacks these ratings can lead to premature wear or even engine sludge.
While the manual suggests a synthetic blend, many enthusiasts and off-roaders prefer a full synthetic oil. Full synthetic options generally offer better resistance to thermal breakdown, which is a major plus if you frequently tow or drive in extreme heat. Always check the back of the bottle for the Ford API SN or SP certification.
Oil Capacity Requirements
The 2.7L EcoBoost engine in your 2018 F-150 has a capacity of 6.0 quarts (5.7 liters). This includes the volume held within the oil filter. It is a good practice to buy a 5-quart jug and an extra single quart to ensure you have exactly what you need on hand.
Never overfill the engine, as this can cause aeration, where the crankshaft whips air into the oil. Foamy oil does not lubricate well and can lead to pressure drops. Conversely, running low on oil is a death sentence for the turbos, which rely on a constant, pressurized oil supply for cooling.
The Importance of the Correct Filter
The 2018 2.7L engine uses a cartridge-style oil filter rather than a traditional spin-on canister. The specific part number is usually Motorcraft FL-2062-ST. This filter sits on top of the engine, making it easy to access, but it requires careful handling of the included O-rings.
When you buy your filter, ensure it comes with the large O-ring for the cap and the two smaller O-rings for the center post. Replacing these seals every time is mandatory to prevent internal leaks and pressure loss. Lubricate the new O-rings with a dab of fresh oil before installation to prevent tearing.
Why 5W-30 is Non-Negotiable for the 2.7L EcoBoost
When discussing the 2018 ford f150 2.7 oil type, we have to look at the engineering behind the engine. The 2.7L EcoBoost is a marvel of power density, utilizing twin turbochargers to punch way above its weight class. These turbos spin at incredibly high speeds and generate intense heat.
A 5W-30 oil is thick enough to provide a protective barrier for the turbo bearings but thin enough to circulate instantly upon startup. If you were to use a 0W-20, which is common in non-turbo engines, the oil might become too thin under heavy boost. This would leave your engine components vulnerable to metal-on-metal contact.
Furthermore, the 2.7L uses a complex variable cam timing system that relies on oil pressure to function. The wrong viscosity can lead to “cam phaser” rattle or timing errors. Sticking to the 5W-30 weight ensures the hydraulic passages in the engine work exactly as the Ford engineers intended.
Essential Tools for a DIY Oil Change
Before you crawl under your truck, gather the right tools to make the job smooth. The 2018 F-150 has a few unique features that catch beginners off guard. Having everything ready prevents that frustrated trip to the parts store mid-job.
- 27mm Socket: This is required to remove the oil filter housing cap on top of the engine.
- Oil Drain Pan: Ensure it can hold at least 7 or 8 quarts comfortably.
- Replacement Drain Plug: The 2.7L uses a yellow plastic twist-off plug that can become brittle over time.
- Funnel: A long-neck funnel helps prevent spills on the engine cover.
- Clean Rags: For wiping down the filter housing and checking the dipstick.
I highly recommend keeping a spare plastic drain plug in your glovebox. These plugs are designed to be removed by hand or with a pair of pliers, but the plastic tabs can snap. It is a cheap insurance policy for any DIY mechanic or off-roader.
Step-by-Step Oil Change Process
- Warm Up the Engine: Drive the truck for 5-10 minutes to get the oil flowing easily. This helps suspend contaminants so they drain out with the old oil.
- Remove the Filter First: Use your 27mm socket to unscrew the filter cap on top of the engine. Doing this first allows the oil in the filter housing to drain down into the pan.
- Drain the Oil: Locate the yellow plastic plug on the oil pan. Twist it counter-clockwise. Caution: The oil will come out very fast and with significant force; position your drain pan accordingly.
- Replace O-Rings and Filter: Swap the old filter for the new FL-2062-ST. Replace all three O-rings on the cap and post, ensuring they are seated in their proper grooves.
- Reinstall the Drain Plug: Clean the mounting surface and twist the yellow plug back in until it clicks or seats firmly. Do not use tools to overtighten it.
- Add Fresh Oil: Pour in 6 quarts of your chosen 2018 ford f150 2.7 oil type. Use a funnel to keep the engine bay clean.
The “15-Minute Rule”: Avoiding the Most Common Mistake
One of the most unique aspects of the 2.7L EcoBoost is how it manages oil return. Unlike older engines where the oil drops to the pan immediately, the 2.7L has a complex internal structure. If you check the oil level immediately after turning off the engine, it will show as critically low.
You must wait at least 15 minutes after shutting down the engine before checking the dipstick. This allows the oil to drain back from the upper galleries and the turbocharger lines into the sump. Many owners have accidentally overfilled their engines because they didn’t wait for the oil to settle.
If you are at a gas station and want to check your level, do it after you have finished fueling and perhaps grabbed a snack. This patience ensures an accurate reading. If the level is between the two holes on the dipstick after 15 minutes, you are good to go.
Synthetic vs. Synthetic Blend: Which Should You Choose?
While the factory fill for the 2018 ford f150 2.7 oil type is a synthetic blend, many experts suggest upgrading to a full synthetic. Synthetic blends are a mix of conventional and synthetic oils. They are cost-effective and meet the minimum requirements for daily driving.
However, full synthetic oil offers superior molecular uniformity. This means it handles the high-stress environment of a turbocharged engine much better. It is less likely to oxidize or create carbon deposits on the intake valves—a common issue in direct-injection engines like the EcoBoost.
If you live in a climate with extreme cold, full synthetic flows better at sub-zero temperatures. This reduces the “dry start” wear that occurs in the first few seconds of engine operation. For the extra $10 to $15 per oil change, the peace of mind offered by full synthetic is well worth the investment.
Understanding GDI and Oil Quality
The 2.7L EcoBoost uses Gasoline Direct Injection (GDI). In these engines, fuel is sprayed directly into the combustion chamber rather than over the intake valves. Because fuel isn’t washing the valves, oil vapors can bake onto them, causing carbon buildup.
Using a high-quality oil with a low NOACK volatility rating helps minimize these vapors. Oils that meet the latest API SP standards are specifically formulated to reduce low-speed pre-ignition (LSPI) and protect GDI engines. Always look for that “SP” rating on the bottle.
Common Problems and Maintenance Pitfalls to Avoid
One common pitfall is ignoring the Intelligent Oil-Life Monitor (IOLM). This system doesn’t just count miles; it monitors engine temperatures, idle time, and towing frequency. However, for those who do heavy off-roading or short trips in the city, the IOLM might suggest an interval that is too long.
Many experienced mechanics recommend a “conservative” interval of 5,000 miles regardless of what the computer says. This is especially true if you are trying to reach the 200,000-mile mark. Fresh oil is the cheapest insurance policy against timing chain stretch.
Another issue is the plastic oil pan found on some 2018 models. These pans can sometimes develop leaks at the seal. When you are changing your oil, take a moment to inspect the perimeter of the pan for any seepage. If you see oil dampness, it may be time to consult a professional for a pan reseal.
Frequently Asked Questions About 2018 ford f150 2.7 oil type
Can I use 5W-20 oil if 5W-30 is unavailable?
No, you should avoid using 5W-20 in the 2.7L EcoBoost. This engine is specifically clearanced for 5W-30. Using a thinner oil can lead to inadequate lubrication of the turbochargers and may void your powertrain warranty if an oil-related failure occurs.
What is the best 2018 ford f150 2.7 oil type for towing?
For towing, a Full Synthetic 5W-30 that meets Ford WSS-M2C946-B1 is best. Brands like Pennzoil Ultra Platinum or Mobil 1 Extended Performance are highly regarded for their ability to withstand the high oil temperatures associated with pulling heavy trailers.
How often should I change the plastic drain plug?
Ford technically considers the plastic plug to be reusable, but the O-ring on it can flatten over time. Most DIYers replace the plug every 3 to 4 oil changes, or immediately if the plastic tabs show any signs of stress or whitening.
Does the 2018 2.7L EcoBoost have an oil cooler?
Yes, the engine features an oil-to-coolant heat exchanger. This helps the oil reach operating temperature quickly in the winter and sheds excess heat during the summer. This is why maintaining your cooling system is just as important as your oil changes.
