I decided to go synthetic after my first year of ownership.
Then after 3 years of oil changes at the dealer as needed, their oil changer made a mistake and switched me back to regular. I didn't complain too much as they were covering a transmission problem at the same time that I thought I'd have to pay for.
I've been back to regular oil for the last couple years. No worries.
I just don't think I will switch back to synthetic even though I love the loner intervals between changes.
