It's been 80,000 miles and 5 years since the last sample on my beloved Camry V6. We purchased this car new in 1997 and had it for 235,000 trouble free miles when it got sold to a friend. I've been servicing the car on and off for years when the owner would call and ask. Recently the car developed a misfire which I've yet to diagnose and while the car was here, I decided to pull a sample on the oil since the owner didn't remember when was the last time it was serviced Looks like the engine is still doing good, for the most part. I've convinced the owner to let me service it regularly in order to see it reach 400k miles since he doesn't plan to sell it anytime soon. We'll see if he sticks to my 5,000 service recommendation and actually calls when it's time to change the oil. I placed a Blackstone Labs window sticker as a reminder.
Some previous UOA's can be found here, for anyone interested. It usually got 5,000 mile OCIs when I had it. The high bearing wear was present from the very first UOA @ 190,000 miles and stayed consistent. Some daily the engine will surely eat itself to death soon but seems that hasn't happened yet and she's still purring along...
