The 1.5L EcoBoost engine is a marvel of modern engineering, packing the power of a larger displacement engine into a compact, fuel-efficient package. However, the turbocharger spins at incredible speeds and operates at very high temperatures, placing unique demands on the engine oil. Standard motor oils may break down or clog the turbo bearings over time, leading to premature failure. AMSOIL synthetic motor oils are engineered with advanced base stocks and additive packages that resist thermal breakdown, ensuring the turbocharger and engine internals remain lubricated even under the most severe driving conditions. Whether you are commuting in stop-and-go traffic or towing a trailer on a highway, these oils provide a robust barrier against wear.
For the cooling system, maintaining the correct temperature is just as vital as oil lubrication. The 12.5-quart capacity of the cooling system requires a robust antifreeze solution that protects against rust, corrosion, and freezing. AMSOIL’s Passenger Car and Light Truck Antifreeze & Coolant uses a unique poly-organic acid (OAT) formulation that is free of phosphates, nitrates, and silicates. This compatibility ensures it works safely with all cooling system metals, gaskets, and hoses, providing protection for up to 150,000 miles or five years. For those seeking a concentrated solution, the Propylene Glycol Antifreeze offers similar long-term protection and requires mixing with distilled water for optimal performance.
Transmission maintenance is often overlooked but critical for the longevity of the 6F35 automatic transmission found in this model. This unit is subjected to significant heat and load, particularly when the vehicle is used for towing or hauling. Using a premium synthetic automatic transmission fluid like the AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid helps the fluid remain stable in sub-zero temperatures and during heavy use. This synthetic formulation resists oxidation and sludge buildup, which are common causes of transmission shift quality issues. The AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid provides a cost-effective alternative that still delivers the benefits of 100% synthetic technology to protect against wear and maintain fuel efficiency.
Beyond the engine and transmission, the drivetrain components also benefit from synthetic lubrication. The Power Transfer Unit (PTU) on all-wheel-drive models requires a specific viscosity, typically 75W-140, to prevent thermal runaway, a condition where the fluid gets too hot and breaks down. AMSOIL SEVERE GEAR 75W-140 100% Synthetic Gear Lube is specifically designed to control this thermal runaway while protecting against rust and corrosion. For the rear differential, which typically holds around 2.4 pints, AMSOIL SEVERE GEAR 80W-90 100% Synthetic Gear Lube offers excellent protection for GL-5 applications, reducing operating temperatures and extending the life of seals and gears.
When it comes to fluid changes, capacity and specifications must be followed precisely. The engine requires 4.3 quarts of 5W-20 motor oil with a filter change. The torque specification for the drain plug is 21 ft-lbs. For the automatic transmission, a total fill for the 6F35 unit requires 9 quarts, though a drain and fill will use slightly less. The PTU takes 1.1 pints of synthetic rear axle lubricant, and the rear differential requires 2.4 pints of 80W-90 SEVERE GEAR 80W-90 100% Synthetic Gear Lube. Always verify fluid levels after refill to ensure the vehicle is operating within safe parameters. Additionally, the AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid should be used to ensure reliable stopping power and ABS responsiveness.
Vehicle Background and Performance
The 2018 Ford Escape is a compact SUV that plays a significant role in Ford’s lineup, sitting at the intersection of practicality and performance. Part of the third-generation Escape that debuted in 2013, this model year continues the trend of using small-displacement, turbocharged engines to meet stringent fuel economy standards without sacrificing too much power. The 1.5L EcoBoost engine is a compact four-cylinder that delivers a surprising amount of low-end torque, making the vehicle feel more responsive than its displacement might suggest. This engine family is known for its efficiency, often achieving excellent highway mileage, which makes the Escape a popular choice for daily commuters and families alike.
In terms of design and utility, the 2018 Escape offers a versatile interior with a wide range of trim levels, from the base S to the sporty ST line. The vehicle’s platform is derived from Ford’s C2 architecture, which shares DNA with the Ford Focus and Mustang, providing a foundation that handles well on the road. The cabin is designed with driver-focused ergonomics, and the infotainment systems have matured to offer seamless connectivity, a hallmark of modern Ford vehicles. The Escape’s reputation is built on its blend of utility, reliability, and the distinctive character of the EcoBoost engine, which has become a signature for the brand.
Despite its strengths, the 2018 Ford Escape 1.5L is not without its maintenance considerations. One common issue reported by owners involves the turbocharger and the associated cooling system. The high operating temperatures can lead to coolant degradation if not managed properly, potentially resulting in leaks or overheating. Using a high-quality synthetic antifreeze like AMSOIL helps mitigate this risk by providing superior corrosion protection and stability at extreme temperatures, preventing the degradation of coolant properties that can lead to overheating issues.
Another potential area of concern for this engine is the buildup of carbon deposits on the intake valves and piston tops, a characteristic sometimes associated with direct injection engines. Over time, this buildup can affect performance and fuel economy. Regular use of fuel system cleaners and the use of high-detergent synthetic motor oils can help keep these components clean. AMSOIL oils are formulated with enhanced detergent packages that fight sludge and deposits, helping to maintain engine cleanliness and performance over the long haul.
Turbocharger reliability is also a focus for owners of this vehicle. The high-speed bearings of the turbo require oil that does not coke or break down under heat. Many owners have found that switching to a premium synthetic motor oil extends the life of their turbos and prevents the oil coking issues that can plague synthetic oils that are not robust enough for the specific thermal demands of the EcoBoost. By using AMSOIL Signature Series 5W-20 100% Synthetic Motor Oil, owners can ensure that the turbocharger receives the necessary protection to operate smoothly for the full service interval.
Additionally, the 6F35 automatic transmission has seen reports of shudder or harsh shifting in some vehicles, often attributed to fluid breakdown or contamination. Ensuring that the transmission fluid is changed at recommended intervals or earlier with a premium synthetic fluid can resolve these issues. The synthetic formulation resists oxidation and shearing, which helps maintain the fluid’s ability to transmit power smoothly and engage clutches correctly. This proactive maintenance approach can prevent costly transmission repairs and keep the driving experience smooth and responsive.
Finally, for those who utilize the all-wheel-drive system, the Power Transfer Unit (PTU) is a critical component that requires specific attention. The PTU is lubricated by the engine oil in some designs, but in the 2018 Escape, it has a separate fill point and requires a specific synthetic gear lube. The lack of proper lubrication or the use of the wrong viscosity can lead to premature failure, often accompanied by loud whining noises. Using AMSOIL SEVERE GEAR 75W-140 100% Synthetic Gear Lube specifically addresses the thermal runaway issues associated with the PTU, ensuring that the unit remains cool and lubricated regardless of how often the vehicle is used for off-road or towing purposes.
