I finally changed my oil. The change was done at approximately 77,000 miles with Shell Rotella-T Synthetic 5w40 and Purolator Pureone.
The process itself was very simple. However, I managed to get myself into trouble by putting more oil than what my engine can handle. Thankfully, Arco helped me fix my issues by draining the extra oil from the oil filter.
While changing the oil, I noticed that the used oil was black and thick (a very good indication of probable oil starvation). Arco pointed out that the oil that left the oil pan was not the amount that went in. So, in theory, my engine could have been starving for oil because I haven't changed it in around 12,000 miles. We also noticed that when we drained some of the new oil, it was still pretty dirty. The oil that leaked from the oil filter wasn't as thick as the used oil, but it was almost as black. To remedy this effect, I'm going to change my oil again in 3,000 miles.
Overall, my impressions were satisfactory, but not impressive. The car is definitely smoother, however I feel like I had better results with Castrol Syntec. I'm not sure if it's because I haven't changed the transmission gear oil yet, or if it's because my car still has some of the old, burnt oil lingering in the engine. I'll definitely do another review of Shell Rotella T on my next oil change, and when I do my Gear Oil.
