2007 Camry 4-cylinder at 150k miles. Like every other Camry from that generation, she burns oil because of the darn oil return holes in the pistons. Over the past couple of years she has been used mostly for trips around town, so now she is burning oil seemingly more and more.
I know there are a lot of posts regarding how to offset the impacts over the years, but has anyone tried adding Gumout Multi-System Tune-Up to clean up the pistons a bit? I'm not looking for miracles, but if someone has tried it with success, I would be willing to throw a bottle in for a number of refuels and an oil change or two. I am typically hesitant about additives because most seem to turn out to be snake oil, but reading decent reviews on the Gumout and learning more about polyetheramine (PEA) I am willing to give it a shot.
Appreciate any advice or anecdotes.
