I usually find it very difficult to assign adjectives to an oil's performance based on feel or sound but this recent run and subsequent fill have been significantly different... to my amazement.
I just used Mobil Super Synthetic 5W30 for only ~3000 miles and in this vehicle, it was very noisy. I didn't like at all. I wasn't sure if it was the oil or the car was past it's break-in miles at 20,000. So i emptied it out and replaced with Shell Rotella Gas Truck 5W30. The used MSS went to the lawn crew that does our community upkeep.
The difference is very noticeable and surprising. The vehicle is much smoother...even more than anything else i've ever used. It's diffucult to describe other than the Kia is just much smoother and quieter. Why? I have no idea.
My apologies to all of you i doubted in the past. You are correct, sometimes the difference is obvious.
