2018 Nissan Titan Fluid Type Specifications

Quick Reference

Engine Oil

The 2018 Nissan Titan comes with a choice of two engines: the 5.6L Endurance V8 gasoline engine and the 5.0L Cummins V8 turbodiesel engine. Each engine has specific oil requirements.

For the 5.6L Endurance V8 gasoline engine, Nissan specifies a 0W-20 full synthetic engine oil. It is crucial to use an oil that meets or exceeds API SN (or later, such as API SP) resource-conserving standards. The capacity for the 5.6L engine is typically around 6.7 quarts with a filter change. Always verify the exact capacity in your owner's manual or OEM service information, as slight variations can occur.

For the 5.0L Cummins V8 turbodiesel engine, Nissan recommends a low-ash API CJ-4 or later (such as CK-4) engine oil. The viscosity generally recommended is 5W-40. The capacity for the diesel engine is significantly higher, often around 7.5 quarts with a filter change. Using the correct low-ash oil is critical for the longevity of the diesel particulate filter (DPF) and other emissions control components. Incorrect oil can lead to premature DPF clogging and costly repairs.

Intervals and Pitfalls: Engine oil and filter should typically be changed every 5,000 to 7,500 miles or every 6 months for gasoline engines, and more frequently (e.g., every 5,000 miles or 6 months) for diesel engines or vehicles used for heavy towing or in severe conditions. Always refer to your owner's manual for precise service intervals. Using conventional oil or an incorrect viscosity can lead to increased engine wear and reduced fuel economy.

Engine Coolant

The 2018 Nissan Titan uses a Nissan Long Life Antifreeze/Coolant, which is typically blue in color and is an ethylene glycol-based, silicate-free, phosphate-free, and amine-free formula. This is a type of Organic Acid Technology (OAT) coolant. It meets Nissan's L250 type specification. It is crucial not to mix different types of coolants (e.g., OAT with HOAT or IAT), as this can lead to chemical reactions, gel formation, and corrosion, severely compromising the cooling system's effectiveness. The total system capacity can range from approximately 10.5 to 13.0 quarts, depending on the engine and specific configuration.

Intervals and Pitfalls: Nissan typically recommends draining and refilling the coolant every 60,000 miles or 5 years initially, then every 30,000 miles or 2 years thereafter. However, always consult your owner's manual for the most accurate service schedule. Using tap water instead of distilled water when mixing concentrate (though Nissan's coolant is usually pre-mixed) or using an incompatible coolant type are common pitfalls that can shorten component life.

Transmission Fluid

The 2018 Nissan Titan can be equipped with either a 7-speed automatic or a 5-speed automatic transmission. Each requires a specific type of fluid.

The 7-speed automatic transmission requires Nissan Matic S ATF. This is a synthetic blend fluid designed specifically for Nissan transmissions to ensure smooth shifting and optimal performance. The total capacity is approximately 10.5 to 13.0 quarts, but a drain and fill will typically replace only a portion of the fluid. Always verify the fluid level using the dipstick according to the manufacturer's procedure.

The 5-speed automatic transmission (found in some earlier models or specific configurations) requires Nissan Matic J ATF. While Matic S is often considered backward compatible with Matic J in many applications, it's always best to stick with Matic J if that's what's specified for your specific 5-speed unit to avoid any potential issues.

Intervals and Pitfalls: Nissan generally recommends inspecting transmission fluid at regular service intervals and replacing it under severe driving conditions (e.g., heavy towing, frequent stop-and-go) typically every 60,000 miles. For normal driving, some owners opt for every 90,000 to 100,000 miles, but always prioritize the owner's manual. Never use a
