The high mileage stuff is just marketing nonsense. And don't fall for the "use thicker oil" myth.

I would like to know if there would be any benefits (or problems such as leaks developing) if I use the synthetic.
It would be a switch from conventional to synthetic and a viscocity change as well.
Any/all recommendations would be appreciated
NO NEED TO change at 80,000 miles keep using the Dino PYB 5w30 as from day 1.
No "need" to change nor stay the same...
Wrong. No need to change just because someone posts here on this site.
Plenty of new members have vehicles performing well and with good oil change regimes never having consulted BITOG.
We can learn from them.

80000k miles is considered high mileage anyway.
Not since about 1979...
Wrong again, high mileage oils were advertied for vehicles over 75000 miles in the last 10 years.

Please do not get sucked in to go thinner at this stage.
More dis-benefits than benefits, despite what our learned colleagues believe.
Do you sell parts at Autozone?
No, but do you sell parts?
What's the "dis-benefit?" Better fuel economy?
Seals usually hardened after 80000 miles and 7 years of age.
Vehicles of this mileage and age were not recommended for switching by a some oil manufacturer some years ago.
If you are prepared to help fund the OPs repairs should weeping or leaks occur then I may agree with you.
Yes this my opinion and observation and it is just as valid as yours.
Faster flow at startup possibly helping where about 70-90% of actual wear happens?
How much faster is the flow between a 0w-20 and 5w30 in real world conditions.
This comment is bordering on being negligible again my opinion and observation and just as valid as yours.
My responses are below each quote you challenged.
And I don't want to turn it into a debate.

A debate? He asked for opinions! I gave mine and everyone chomps the same myths. My opinion is that I'd use 0W-20 in New Hampshire in the winter. Have you ever even been there? How much faster does it flow? Probably quite a bit faster in sub zeroF temps. Have you ever driven in -26C temps or started a car in them?..
I challenged them as I was challenged, because I think they're wrong. If the OP has lots of 0W-20 on hand there's no reason not to use it as it is now the recommended by the manufacturer.
They don't know really how this Corolla was driven. My nephew had the same engine that was abused in a Celica there and his car actually burned MORE the heavier the oil he used...
