Seeing this thread last saw action 3 yrs. and 11 mos. ago, I am simply updating/clarifying the information for anyone who now owns a 2009 or later 2.7 L 4-cylinder Tacoma. I cannot speak for those who own an earlier model. The "Toyota Recommends" statements are directly taken from my manual.
Oil Used: Mobile 1 or Valvoline 100% Synthetic 0w-20
- Toyota Recommends: "SAE 5W-20 or 0W-20 engine oil may be used. However, SAE 0W-20 is the best choice for good fuel economy and good starting in cold weather."
Oil Quantity Used: 5 qts. (this quantity places oil within the "full" dimple/notch)
- Toyota Recommends: Not Provided; however, Toyota does state, "The approximate quantity of oil needed to raise the level between low and full on the dipstick is indicated as follows: 2.7 L 4-cylinder (2TR-FE) engine 1.4 qt. (1.3 L, 1.1 lmp. qt.)"
Miles Between Changes: 5,000 (what I'm comfortable with; I notice zero negatives)
- Toyota Recommends: Not Provided
- John Doe Recommends: From 3,000 to 15,000, I have heard it all. When I lived in AZ, I changed it every 3,000 or so due to all the fine sand.
Note: I check my oil level either before I turn the vehicle on or 10 minutes after I turn it off. In both situations, the oil has drained into the reservoir where the dipstick takes the measurement. Both tactics are recommended by multiple oil companies...Mobil being one of them. Seems to make a lot of sense too. Running the engine and checking the level during or shortly after turning it off does not take into account the oil within the system.
