The 2021 Toyota Tacoma belongs to the 3rd generation (2016-2023), built with 2.7L four-cylinder or the 3.5L 2GR-FKS V6 with Atkinson-cycle operation. It takes 0W-20 full synthetic on the 3.5L V6. Oil changes run 10,000 miles under normal use, 5,000 under severe use. This sits in the middle of the generation run, generally the most sorted point in a design before end-of-run cost reductions.
A 2021 Toyota Tacoma is 5 years old in 2026, which at an average 12,000 miles a year puts it around 60,000 miles - the interval that decides its future. At roughly 60,000 miles a vehicle enters the window that most separates the ones that reach 200,000 miles from the ones that do not. Keeping up with whatever its own manufacturer schedule calls for here is what avoids expensive failures later. The next milestone on its own schedule is 90,000 miles, roughly 2.5 years away at average use - a repeat of the 30,000-mile service.
The fault most worth knowing about on this generation is Lower fuel economy than expected relative to the previous generation. Owners also report Transmission hunting and harsh shifting, partly addressed by software updates; and Rear differential leaks on some builds. None of these are certainties on any individual vehicle - they are the patterns worth checking for when you buy or when a symptom appears.

The table above is indexed by service interval. This is the same schedule indexed by odometer reading, for when you know your mileage and want the list. If your odometer sits between these figures, work back to the last one you passed and catch up anything skipped.
