How much diff fluid does a 2015 Tacoma hold?
On a 2015 Tacoma, differential fluid capacity depends on drivetrain: 4x4 versions use both a front and a rear differential, while 2x4 models have only a rear differential. A typical 4x4 holds about 2.0 quarts in the front differential and about 2.6 quarts in the rear differential (roughly 4.6 quarts total), whereas a 2x4 holds about 2.6 quarts for the rear differential alone.
Drivetrain configurations and capacities
The numbers below reflect common specifications from Toyota service data. Exact capacities can vary slightly by axle ratio or model revision; always verify with the owner’s manual or service manual for your exact VIN.
4x4 Tacoma: Front and rear differentials
For quick reference, here are the typical capacities for a 2015 4x4 Tacoma:
- Front differential capacity: about 2.0 quarts (approximately 1.9 L)
- Rear differential capacity: about 2.6 quarts (approximately 2.5 L)
Concluding: Filling both diffs on a 4x4 Tacoma typically totals roughly 4.6 quarts of gear oil, with a practical range around 4.6–5.0 quarts depending on the rear axle specification and how full you fill to the indicated mark.
2x4 Tacoma: Rear differential only
For quick reference, here is the rear-differential capacity for a 2015 2x4 Tacoma:
- Rear differential capacity: about 2.6 quarts (approximately 2.5 L)
Concluding: A 2x4 Tacoma requires about 2.6 quarts of gear oil for the rear differential during a drain-and-fill service, with little to no front-diff service needed.
Oil type and service tips
Use the gear oil specified in the owner’s manual. Toyota commonly recommends GL-5 gear oil in the appropriate viscosity (often 75W-90). Some service intervals call for a full flush, while others use a drain-and-fill approach. Ensure the vehicle is level during filling and fill to the indicated full line for each differential. When in doubt, consult the service manual or a Toyota technician for your exact axle configuration.
Summary
In summary, a 2015 Toyota Tacoma’s differential fluid capacity depends on drivetrain. A 4x4 model typically requires about 4.6 quarts total to fill both front (≈2.0 qt) and rear (≈2.6 qt) differentials, with a practical range up to around 5.0 quarts. A 2x4 model needs about 2.6 quarts for the rear differential only. Always verify exact figures in the owner’s manual and use the correct gear oil type for your axle configuration.
