Ten years isn't even that old. Synthetic oil has it's benefits (more protection, better low temp performance, high heat performance), its more expensive but you can run longer oil change intervals (10-15k+). Just make sure your car doesn't burn/consume oil; you won't be able to take advantage of the long oci and might as well stick with conventional.

Definitely overkill, I would at least double that with a good filter. Fram XP, Napa Gold, CarQuest Blue, M1, Wix XP, etc.
Never blindly double your oil change interval because you are using synthetic. There are many factors in how quickly an engine can degrade motor oil. Things like small sump capacity or use of forced induction (especially turbocharged engines) can degrade motor oil much faster. If you plan on keeping your vehicle long term, do an oil analysis to properly determine how long you can run an oil before the additive pack of the oil deteriorates too far.

Well in that case he could probably quadruple his OCI. It's a Toyota after all.

Is your vehicle still under warranty?
If yes, I would stick to that OCI until the warranty period is over!
No warranty - 200k+ kms on the car.

I'm going to take a closer look at my oil when I do the next change. I've had conventional oil turn to sludge in my car before at around 10k km. I screwed up and didn't change the oil for too long.
It's probably a good idea to stick close to the manufacturing OCI (definitely not going to go double)

So I'm gonna go on vacation for 5 weeks and the car is gonna be garage parked for that time period. I put in Pennzoil Platinum in November....it's now over 6,500km. Car is new and underwarranty. Should I change the oil before or after I get back?
