Ford F150 Oil Consumption: What You Need to Know

It's a concern that can leave many a motorist scratching their head and reaching for their dipstick more often than they'd like: excessive oil consumption in their vehicle. For owners of certain Ford F150 trucks, this has become a more prevalent worry, with specific model years and engine configurations drawing particular attention. Reports and legal actions suggest that some Ford F150s, notably those manufactured between 2018 and 2020 and equipped with the popular five-litre V8 engine, may be experiencing issues that lead to an unusually high rate of oil consumption. This has not gone unnoticed, with a class-action lawsuit being filed, highlighting the seriousness of the matter for affected owners.

Understanding the Concern: Excessive Oil Consumption

Excessive oil consumption in a vehicle refers to a rate of oil usage that is significantly higher than what is considered normal. While all internal combustion engines consume a small amount of oil as part of their normal operation – lubricating moving parts, sealing combustion chambers, and cooling components – there's a tipping point where this consumption becomes problematic. This can manifest as the need to top up the oil much more frequently than expected, potentially leading to low oil levels if not monitored closely. Low oil levels, in turn, can cause severe damage to the engine, including increased wear, overheating, and ultimately, catastrophic failure. For F150 owners, the worry is that their powerful trucks, known for their durability and capability, might be falling victim to an inherent design or manufacturing flaw.

The Focus: 2018-2020 Ford F150 with 5.0L Engines

The allegations of excessive oil consumption appear to be concentrated around a specific cohort of Ford F150 trucks. The model years 2018, 2019, and 2020, when fitted with the 5.0L Coyote V8 engine, are frequently cited. This engine is a staple in the F150 lineup, celebrated for its blend of power, torque, and V8 sound. However, it seems that for some of these particular trucks, this highly regarded powertrain might be experiencing some unwelcome side effects. The exact nature of the defects causing this heightened oil consumption is complex and can stem from various sources within the engine's design and manufacturing process. It's important to note that not every F150 from these years will exhibit this problem, but the prevalence of reports and the legal action indicate a systemic issue affecting a significant number of vehicles.

Potential Causes of Excessive Oil Consumption

Pinpointing the exact cause of excessive oil consumption in any engine can be challenging, as multiple factors can contribute. In the case of the affected F150 models, several potential culprits have been discussed and investigated:

• Piston Ring Issues: Worn or improperly seated piston rings are a common cause of oil consumption. These rings are designed to seal the gap between the pistons and the cylinder walls, preventing oil from entering the combustion chamber. If they are faulty, oil can bypass the rings and be burned during combustion.
• Valve Stem Seals: The valve stems guide the valves into and out of the combustion chamber. Valve stem seals prevent oil from seeping down the valve guides into the combustion area. If these seals degrade or fail, oil can enter the cylinders.
• PCV System Malfunctions: The Positive Crankcase Ventilation (PCV) system is designed to remove blow-by gases from the crankcase. A malfunctioning PCV system, such as a clogged or faulty valve, can increase crankcase pressure, forcing oil past seals and into the intake manifold or combustion chambers.
• Oil Separator Design: Some analyses suggest that the design of the oil separator or catch can system in these engines might not be sufficiently effective in preventing oil mist from entering the intake system, leading to oil being ingested and burned.
• Manufacturing Tolerances: In some instances, minor variations in manufacturing tolerances for engine components like pistons, cylinders, or valve guides could lead to increased oil consumption over time.

The Class Action Lawsuit

The filing of a class-action lawsuit against Ford Motor Company underscores the gravity of the oil consumption issue. Such lawsuits are typically initiated when a significant number of consumers experience similar problems with a product, and these problems are believed to be caused by a defect. The lawsuit aims to hold the manufacturer accountable and seek remedies for owners who have incurred costs related to diagnosing and repairing the oil consumption problem, or who may suffer future damage to their engines. For those involved, this legal action represents a collective effort to address a widespread concern and seek fair compensation.

What Can F150 Owners Do?

If you are an owner of a Ford F150, particularly a 2018-2020 model with the 5.0L engine, and you suspect you are experiencing excessive oil consumption, here are some steps you can take:

1. Monitor Oil Levels Regularly: The most crucial step is to diligently check your oil level using the dipstick at every fuel stop or at least once a week. Note down the oil level and the mileage.
2. Document Everything: Keep meticulous records of all oil added, including the date, mileage, and quantity. Also, record any symptoms you notice, such as blue smoke from the exhaust, rough idling, or engine warning lights.
3. Consult Your Owner's Manual: Familiarise yourself with Ford's recommendations regarding normal oil consumption for your specific model.
4. Seek Professional Diagnosis: If you observe a consistent and significant drop in oil level, it is imperative to take your truck to a qualified Ford dealership or a trusted independent mechanic. Explain your concerns and provide them with your documentation.
5. Inquire About Recalls or Service Bulletins: Check with your Ford dealer or Ford's official website for any technical service bulletins (TSBs) or recalls that may have been issued regarding oil consumption for your vehicle's year and engine.
6. Understand Your Legal Rights: If you are part of the affected model years and suspect your vehicle has this defect, research the details of the class-action lawsuit to understand if you are eligible to join or if there are specific procedures you need to follow.

Is it Always a Serious Defect?

While the class-action lawsuit focuses on specific model years and engines, it's worth reiterating that not all instances of oil consumption are indicative of a major defect. As mentioned, a small amount of oil consumption is normal. Factors that can temporarily increase oil consumption include:

• Driving Habits: Aggressive driving, frequent short trips where the engine doesn't reach optimal operating temperature, and high-speed driving can sometimes lead to slightly increased oil consumption.
• Oil Viscosity: Using an oil with a lower viscosity than recommended by the manufacturer can sometimes lead to increased oil consumption.
• Engine Age and Mileage: As engines age and accumulate mileage, natural wear and tear on components like piston rings and valve stem seals can lead to a gradual increase in oil consumption.

However, if you notice a sudden increase in oil usage, or if the consumption rate far exceeds what's outlined in your owner's manual, it's a strong signal that a deeper issue may be at play.
