Check your dipstick O-rings!

All good. I wouldn't be mad if she had a third gen 4runner! Also her MAF sensor was cleaned when I checked the PCV, I believe. Or the OCI prior. I'd have to check my spreadsheet.

That engine did not see 5k OCIs before you bought it. More like 15k OCIs.

I would do Supertech Synblend High Mileage every 3k, at least until a nearby rooster crows 3 times in 5 minutes.
Don't use a high trapping filter either. Use a high flow like Fram Extra Guard, at least until a nearby pig storms your front door carrying a load of mud.
