I bought an 08 Camry last month. Changed the oil when I brought it. I used Full synthetic 5w-20. I know the 2AZ-FE is known to burn oil. I have about 700 miles on the new oil. Checked the oil level and it's right in the middle of the full and low mark. Any way to reduce oil consumption? Maybe tossing in an additive? Cars got 143k miles on it.
