Engine Oil and Filtration
The heart of your 2016 Transit-350 is the 3.5L EcoBoost engine. This turbocharged powerplant demands high-performance lubricants that can withstand extreme heat and pressure. For the best protection, AMSOIL Signature Series 5W-30 is the top recommendation. It is engineered to provide superior wear protection and is capable of extended drain intervals, making it a cost-effective choice for fleet owners or daily drivers alike. The oil’s robust additive package ensures that the turbocharger and other critical engine components remain free from carbon buildup and sludge.
For owners seeking a balance between premium performance and extended drain intervals, AMSOIL Extended-Life 5W-30 offers a compelling alternative. It is optimized for up to 20,000 miles of use between oil changes while maintaining excellent cleaning properties. If you are looking for a more economical option that still delivers the benefits of synthetic technology, the AMSOIL OE 5W-30 is a reliable choice that outperforms conventional oils in key areas. For vehicles with over 75,000 miles, the High-Mileage 5W-30 formula includes boosters that reduce sludge and consumption, helping older engines run smoother.
Filtering is just as critical as the oil itself. A high-quality filter ensures that contaminants do not bypass the system and damage the engine. The AMSOIL Oil Filter features a 99% filtering efficiency at 20 microns and holds more than competing filters to capture small wear particles. Alternatively, the WIX XP Oil Filter offers premium media improvements over original equipment manufacturer filters, providing an excellent choice for those who prefer aftermarket brand reliability. The standard WIX Oil Filter is also a solid option for conventional change intervals. The engine oil capacity for this vehicle is 5.9 quarts when the filter is included, so be sure to add the correct amount and check the level after refilling.
Transmission and Drivetrain Care
The 2016 Transit-350 equipped with the 6-speed 6R80 transmission requires a fluid that can handle the torque and heat generated during heavy hauling. While a full refill requires 13.1 quarts, the initial fill capacity is lower. AMSOIL Signature Series Fuel-Efficient Automatic Transmission Fluid is formulated to withstand the rigors of towing, ensuring that the transmission shifts smoothly even under load. It is designed to remain fluid in sub-zero temperatures, providing reliable operation in winter climates where other fluids might thicken and cause shifting issues. For those needing a cost-effective option that meets Ford specifications, the AMSOIL OE Fuel-Efficient fluid provides protection against wear and oxidation.
The rear differential also plays a crucial role in the vehicle’s performance. Whether you have a standard differential or a limited-slip setup, the AMSOIL SEVERE GEAR 75W-85 is the recommended lubricant. This synthetic gear lube controls thermal runaway, a common issue in heavy-duty applications, and helps protect against rust and corrosion. The capacity varies slightly between standard and limited-slip rear axles, ranging from 5.7 to 5.9 pints. Using this high-quality lube ensures that your drive components operate smoothly and that the oil seals last longer, preventing costly leaks and maintenance issues.
Coolling System and Brake Safety
Keeping the engine at the correct temperature is vital for the longevity of the 3.5L engine. The cooling system requires a fluid that offers superior corrosion protection and does not boil over under heavy load. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mix formulation that protects all cooling system metals, gaskets, and hoses. It is designed to last up to 150,000 miles or 5 years, significantly reducing the frequency of coolant flushes. For those who prefer a concentrate, the Propylene Glycol Antifreeze is available for mixing, offering protection up to 1,000,000 miles in heavy-duty applications and ensuring that the engine does not overheat during summer months or high-altitude driving.
Brake safety is paramount, especially for a heavy vehicle that may be carrying substantial loads. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid maintains a stable viscosity across a wide temperature range, preventing the spongy feel that can occur with aging conventional fluids. This stability ensures that your ABS and traction control systems respond quickly and accurately, giving you maximum stopping power when it matters most.
Additional Fluids and Maintenance
Beyond the essential fluids, maintaining the fuel system and general vehicle cleanliness can further extend the life of your Transit. The AMSOIL P.i.® Performance Improver gasoline additive is a powerful tool for restoring up to 14% horsepower and cleaning GDI fuel injectors. Using this additive helps prevent carbon buildup and improves fuel economy, ensuring that the engine runs efficiently throughout its service life. For vehicle owners who store their vans or have them idle for long periods, AMSOIL Gasoline Stabilizer keeps fuel fresh for up to 12 months, preventing varnish and gum buildup that can clog injectors.
During the colder months, the ability of the power steering fluid to flow at low temperatures is crucial. The recommended fluid for this vehicle is a Motorcraft Mercon LV equivalent, which can be effectively replaced by the AMSOIL Signature Series or AMSOIL OE Fuel-Efficient Automatic Transmission Fluid. This ensures that the steering remains responsive even in freezing conditions. Additionally, for general maintenance and protection, the AMSOIL Synthetic Multi-Purpose Grease offers excellent resistance to thermal degradation, making it suitable for various chassis points. To protect the vehicle’s metal surfaces from salt and corrosion, the Heavy-Duty Metal Protector leaves a durable, wax-like coating that repels water and moisture.
