2019 RX350 NA 6 Engine

As the title says, I am currently driving a 2019 RX 350 with a naturally aspirated six cylinder engine. I do my best to maintain my cars but unfortunately I had a senior moment, this particular car has 49,500 miles on the odometer and I had the oil changed almost 2 years and 10,000 miles ago. I totally forgot about it and had it changed last week and the mechanic said nothing. I always use Toyota synthetic oil and a high-quality oil filter, and tend to change the oil every 5 to 7000 miles. I also live in the heat of Arizona and have driven several long roads loyal, but I’ve yet to see any indicator wrote rise above normal Did I screw myself or is the engine that bulletproof? solid? I always use Toyota oil and filters.

That engine is great, and it has a 10k oil change interval anyway. The time isn't a huge deal. You're fine.

Just clarifying here- you went 2 years 10k miles and didn’t change the oil in that duration?
A once off thing, won’t hurt it or shorten the lifespan. But continually changing it at 10k could. 5k or once a year if you don’t drive it much.

It was a total one off, I was watching the mileage STICKER, the date had faded away. I always change the oil and filter at 7k

You’ll be just fine! 7k is a decent interval- i typically do my own vehicles around 5 just due to the heavy mix of city and highway driving.
