I recently purchased a new 2016 IS 300 2GR-FSE engine with port and direct injection. Calls for 0W-20 and takes 6.7 quarts with a 10K change interval.
I am very willing to do this, but was burned on my last vehicle following the manufacturers recommendations. I had a 2012 Acura TL 3.7L engine. Ran 5W-20 synthetic oil at intervals recommended by the motor monitor. Usually 6K miles. At 60K started using oil and at 70K the engine was replaced due to coked rings.
My question. (and probably difficult to answer). Did I just get stuck with a poor engine design in the Acura or could my driving habits have hastened the coking of the rings? If it was just poor engine design then I assume I could go the full 10K with no issues in the Lexus. If it is driving pattern then perhaps I should change it sooner. I really have no issues with early oil changes if it can enhance engine longevity.
Thanks for your thoughts.
