Engine oil

• Spec: Use SAE 0W-20 that meets ILSAC GF-5 (or newer GF-6A) and API Resource Conserving categories (API SN/SN Plus/SP). Toyota Genuine 0W-20 is acceptable but not required if the oil meets these specs.
• Capacity: I4 ~6.0–6.2 qt; V6 ~6.1–6.4 qt with filter. Always verify by VIN/engine and check the dipstick after filling.
• Interval: Normal service up to 10,000 miles/12 months with full-synthetic 0W‑20; severe use (towing, dusty, short trips) 5,000 miles.
• Pitfalls: Do not overfill; use a new drain plug gasket and the correct cartridge/canister filter parts. Avoid heavier viscosities unless ambient temps or OEM TSB allow; 5W‑20 may be used only in emergencies and should be replaced with 0W‑20 at the next change.

Engine coolant

• Spec: Toyota Super Long Life Coolant (SLLC), pink, premixed 50/50, phosphated organic acid technology (P-OAT), silicate/borate/nitrite-free. Toyota PN 00272‑SLLC2.
• Capacity: I4 ~7.5–8.5 qt; V6 ~9.5–10.5 qt depending on model and heater core routing.
• Interval: Factory fill 100,000 miles/120 months; thereafter every 50,000 miles/60 months.
• Pitfalls: Do not mix with “universal” green, Dex‑Cool, or older Toyota red LLC. Mixing chemistries shortens life and can gel. Use vacuum fill or proper burping procedures; some 3.5L trucks trap air at the heater core if not fully warmed and bled.

Automatic transmission fluid (ATF)

• Spec: Toyota Genuine ATF WS (World Standard), JWS 3324. Do not substitute “multi-vehicle” ATF unless it explicitly states Toyota WS/JWS 3324 approval.
• Capacity: Total ~10–12 qt; drain & fill typically ~3–4 qt. Fluid level is set by temperature with the overflow standpipe—no dipstick.
• Interval: Toyota labels WS as “lifetime” under normal use; many professionals recommend drain-and-fill every 60,000–90,000 miles, sooner with towing/off-road.
• Pitfalls: Never mix WS with Dexron/Mercon. Level must be set with scan-tool temp or a thermometer at the test port; incorrect level causes flare, shudder, or overheating. Always confirm the fill and check plug torque and use new crush washers.

Manual transmission (if equipped)

• Spec: Toyota Genuine Manual Transmission Gear Oil LV 75W (MT‑LV, PN 08885‑81080). This is a low-viscosity GL‑4-type oil tailored for Toyota synchros.
• Capacity: ~2.2–2.6 qt depending on drivetrain.
• Interval: 30,000–60,000 miles based on duty cycle; more frequent with water crossings or dust.
• Pitfalls: Do not use GL‑5 hypoid gear oil in the manual transmission; it can damage synchros. Avoid “universal” MTFs unless they specifically meet Toyota MT‑LV.

Transfer case (4WD)

• Spec: API GL‑5 hypoid gear oil 75W‑90 (Toyota Gear Oil LX 75W‑90 acceptable). Some owners prefer 75W‑85 in cold climates; follow OEM guidance.
• Capacity: ~1.5–1.7 qt.
• Interval: 30,000–60,000 miles depending on use; severe off-road/towing may warrant 15,000–30,000 miles.
• Pitfalls: Confirm you have 4WD; 2WD models have no transfer case. Fill until fluid just runs out the fill hole with the truck level. Always loosen the fill plug first.

Front differential (4WD)

• Spec: API GL‑5 75W‑85 (Toyota Differential Gear Oil LT 75W‑85, PN 08885‑02506) or 75W‑90 where ambient temps/load require.
• Capacity: ~1.4–1.7 qt by axle.
• Interval: 30,000–60,000 miles; sooner with water crossings or heavy off-road.
• Pitfalls: Clean around plugs to prevent grit entry. Use new crush washers. Do not confuse with transfer case—both use GL‑5 but are separate sumps.

Rear differential

• Spec: API GL‑5 75W‑85 (Toyota Differential Gear Oil LT 75W‑85) or 75W‑90. The Tacoma’s electronic locking differential (if equipped) is not a clutch‑type LSD—no friction modifier is needed. If an aftermarket clutch‑type LSD is installed, follow that manufacturer’s additive guidance.
• Capacity: ~2.9–3.2 qt depending on axle.
• Interval: 30,000–60,000 miles; more often with towing, sand/mud, or water intrusion.
• Pitfalls: Overfilling can aerate the oil; fill level is the bottom of the fill port with the truck level. Inspect breather for clogging to prevent seal leaks.

Brake fluid

• Spec: DOT 3 (FMVSS No. 116 DOT 3). DOT 4 is compatible but Toyota specifies DOT 3.
• Capacity: Typically under 1 qt for a full system flush.
• Interval: Every 2–3 years regardless of mileage.
• Pitfalls: Keep fluid clean and capped—hygroscopic absorption lowers boiling point. Use ABS bleed procedures if required by scan tool.

Power steering

• Spec/Capacity: Electric power steering (EPS); no hydraulic fluid service.
• Pitfalls: If you see a “PS” reservoir, you’re looking at the brake or washer reservoir—Tacoma EPS has no fluid.

Windshield washer fluid

• Spec: Any reputable washer fluid suited to climate (winter blend where freezing temps occur).
• Capacity: Fill as needed.
• Pitfalls: Do not use engine coolant or plain water in freezing climates. Avoid methanol-heavy concentrates near painted surfaces without proper dilution.

Diesel Exhaust Fluid (DEF)

• Not applicable. The 2017 Tacoma sold in North America was gasoline-only.

Notes: Where ranges are shown, Toyota used multiple driveline and cooling configurations. Always verify by VIN in the owner’s manual or OEM service information.
