Engine Oil
For your 2018 Toyota Tacoma, whether it's equipped with the 2.7L 4-cylinder or the 3.5L V6 engine, the factory specifies SAE 0W-20 full synthetic engine oil. It's crucial to use oil that meets or exceeds API SN or SP specifications. The V6 engine typically holds around 6.2 quarts with a filter change, while the 4-cylinder engine requires approximately 4.8 quarts with a filter change. Always consult your owner's manual for the exact capacity for your specific engine and trim level.
Toyota recommends conventional oil change intervals of 5,000 miles or 6 months, and 10,000 miles or 12 months for synthetic oil, whichever comes first. However, severe driving conditions (towing, extreme temperatures, dusty environments) might warrant more frequent changes. Using the correct viscosity and API rating is paramount for engine longevity and performance, as incorrect oil can lead to increased wear, reduced fuel economy, and potential engine damage. Never mix different oil viscosities or types.
Engine Coolant
Your 2018 Toyota Tacoma uses Toyota Super Long Life Coolant (SLLC), which is a pink, pre-diluted, phosphate-free, silicate-free, and boron-free hybrid organic acid technology (HOAT) coolant. This specific coolant is designed for a very long service life, often up to 100,000 miles for the first change and 50,000 miles thereafter, though always check your owner's manual. The V6 engine typically holds around 9.8 quarts, while the 4-cylinder holds approximately 7.2 quarts.
It is critically important to only use Toyota SLLC or an equivalent that meets Toyota's specifications. Never mix SLLC with other types of coolant (e.g., green conventional, blue, or other OAT/HOAT types) as this can lead to chemical incompatibilities, gelling, reduced corrosion protection, and severe damage to your cooling system components. Always ensure the coolant is diluted 50/50 with deionized water unless purchasing pre-diluted coolant.
Transmission Fluid (Automatic)
For 2018 Toyota Tacoma models equipped with an automatic transmission, the factory specifies Toyota WS (World Standard) automatic transmission fluid. This is a highly specialized fluid designed for Toyota's modern transmissions. The capacity for the V6 automatic transmission is approximately 11.0 quarts, and for the 4-cylinder automatic, it's about 8.7 quarts. Never use
