The 2021 Toyota Tacoma is a rugged, versatile midsize pickup known for its reliability, off-road capabilities, and long-term durability. If you’re a proud owner or a prospective buyer of this iconic truck, understanding the regular maintenance requirements—especially when it comes to engine oil—is crucial for optimal performance and longevity. One of the most frequently asked questions among Tacoma owners is: How many quarts of oil does a 2021 Tacoma take?
In this article, we’ll answer that question thoroughly and dive into all the related details—types of oil, filter changes, why oil matters, and best practices for DIY or professional oil changes.
Understanding Oil Capacity in the 2021 Tacoma
Engine oil is the lifeblood of any internal combustion engine. It lubricates moving parts, keeps the engine cool, cleans internal components, prevents rust, and ensures smooth operation. Knowing the correct oil capacity for your 2021 Toyota Tacoma is essential—especially when you’re performing the oil change yourself or selecting a shop that will.
So, to answer the central question upfront:
The 2021 Toyota Tacoma requires 5 quarts of engine oil during a standard oil change (including the oil filter change). However, this amount may vary slightly depending on the engine type, the type of oil filter used, and whether the oil pan was fully drained.
Breakdown by Engine Type
The 2021 Tacoma comes equipped with two primary engine options:
- 2.7L 4-cylinder engine: Found in the base SR and SR5 trims, this engine also accommodates both automatic and manual transmissions. The oil capacity for this engine is 5 quarts, including the filter.
- 3.5L V6 engine: Fitted in the more advanced trims like the TRD Off-Road, TRD Sport, and Limited, this is the most popular engine choice. The V6 engine also requires 5 quarts of oil (with a new filter) during a complete oil change.
Some users may find that slightly more than 5 quarts might be needed in rare cases (e.g., if the oil pan was not fully drained during a home oil change), but following Toyota’s recommendations and waiting long enough for all oil to drain out should allow for a full fill using 5 quarts.
Oil Fill After Filter Replacement
Toyota (and most manufacturers) recommend replacing the engine oil and oil filter during every oil change.
A new oil filter typically holds some oil internally, which is why the recommended capacity includes it. However, if you’re reusing the filter (not advised), you may only need about 4.5 quarts. That said, changing the oil filter at every service interval—typically every 5,000 to 10,000 miles depending on oil type—is critical for engine longevity.
Types of Oil Recommended for the 2021 Toyota Tacoma
The oil type you choose for your Tacoma affects performance, fuel economy, and engine life. While the basic recommendation is the same across both engines, nuances apply depending on driving conditions and personal choice between synthetic and mineral oils.
