In 2003, the Toyota Tundra offered a 3.4L V6 engine as standard, with the option to upgrade to a more robust 4.7L V8 engine. Both engines require 5W-30 synthetic blend oil. The V6 model holds 5.5 US quarts of oil, while the V8 model can accommodate up to 6.6 US quarts, including the filter. To remove the oil drain plug, which has a 12mm head size, you'll need to apply 18 lbs-ft of torque using a torque wrench.
The 2003 Toyota Tundra requires 5.5 quarts of 5W30 synthetic oil for its standard 3.4L V6 engine, and the upgraded 4.7L V8 engine calls for 6.6 quarts of the same oil.
