I drive my 2012 RX350 about 3,000 miles a year. It now has 32K on it. My last oil change was a year ago using Mobile 1 full synthetic. Mobile 1 says it is good for a year. Lexus says 6 months, I assume using non synthetic.
I live in the Bay Area CA with no freezing weather. The Lexus manual says 10K between oil changes or 6 months. Might it be prudent to just drain the oil, not change the filter (it has just 3K on it) and refill with Mobil 1 and go another year. At that time I will have 6K on the filter with the small amount of oil that was in the filter when the oil was changed. I am looking to mitigate the oxidation or whatever happen to oil over time in the engine. And, our humidity levels are low and the vehicle is garaged. Any thoughts?
