Ask yourself, am I comfortable with changing the fluid at 120k or 150k? Will it help at 120k? Maybe, maybe-not. Will it hurt to go to 150k? Again, maybe, maybe-not. What really counts is what results in you feeling good about your level of upkeep. I changed mine at 100k, despite the manual calling for 150k, 2013 SEL, mostly because it was what I felt good about based on my personal experience from 40+yrs of car upkeep. Trusting your gut may help and in this case is doubtful to hurt. The oil changes a 3k by a lot of folks is a holdover from 30+yrs ago, and a lot of people will not change what works for them. Thanks for the read.
