What should I do in addition to oil change on H3!

Under normal circumstances, I would opt for Dino versus syn oil, and it is something that can be debated forever, and in the end, we will all have to agree to disagree. However, the most important part of any oil change is not to change except when required. Under most circumstances, the 3K oil change has gone the way of the dinosaur.
If you ever question the oil life indicator, then have a sample of your oil sent to a oil analysis lab; such as Blackstones in IN. This will put most minds to ease. Every other oil change I send a sample just to see what the oil is like after X-number of miles. It also shows particles in the oil that should not be there, such as metal. It will give you a breakdown and tell you if some metals are normal for the engine. (Example, LS1 engines were noted for high nickel in the early miles.)
