However, it's important to note that:
* This is the "dry" capacity. You may not need to add the full 4.5 quarts when changing the oil, as some oil will remain in the engine.
* Always check your owner's manual for the most accurate information. It might specify a slightly different capacity depending on the specific model and year.
* It's recommended to use the appropriate viscosity oil for your climate. Consult your owner's manual or a reputable mechanic for the correct viscosity.
By following these guidelines, you can ensure you are using the right amount of oil for your 1985 Toyota 22R engine.
