Curious if there is any real difference between Kendall GT-1 Max 5w20 and Pennzoil Platinum 5w20? Vehicle is a 2019 Subaru Ascent and is my wife's daily driver. Mainly my curiosity about GT-1 Max having titanium is leading to me asking the question. Difference in cost is about +$1 / qt for Kendall with an OCI of 5000 miles. Thoughts?
