The recommended oil for a 2018 Toyota Tundra with a V8 engine is a fully synthetic SAE 0w-20 oil, and both the 4.6L V8 and the 5.7L V8 can hold 8.5 quarts. It is advised to change the oil every 7,500 miles or once a year, whichever comes first, to enhance engine longevity, fuel efficiency, and overall performance. Regular oil and filter changes help to eliminate harmful particles and sludge from the engine, preventing potential issues. Failure to change the oil can lead to engine difficulties as the oil breaks down and becomes less effective, causing increased friction and wear on critical engine components. Synthetic oil outperforms conventional oil as it offers superior protection with reduced friction levels.
