Engine Oil Specs & Service Intervals
Proper engine oil is crucial for the smooth operation and longevity of the 1ZZ-FE engine. Toyota recommends using 5W-30 viscosity oil for this engine. It is important to choose a high-quality oil that meets the API (American Petroleum Institute) specifications of SJ, SL, or SM.
The service intervals for engine oil changes vary depending on driving conditions and usage. However, it is generally recommended to change the engine oil and oil filter every 5,000 to 7,500 miles or every six months, whichever comes first. Regular oil changes help maintain engine performance and protect vital engine components from wear and tear.
