What engine oil should I run in my son’s 2019 TRX 90? Pro Honda GN4 10w-30, 10w-40, or synthetic Honda HP4 10w-30, 10w-40?
We are in Southeast Louisiana.
Thanks!

I’d say don’t overthink that one. Definitely don’t stress over the synthetic/Dino choice. With your warm summer temps I’d probably go 10/40.

Honda moved to 10W30 after the 2007 model year. Wouldn't waste the money on Synthetic for the 90. We only use it when/if customer request.

Except for Pioneer/Talon sub trans (Moly syn/petroleum blend) and Forza scooters (those recommend 10w30 full syn).

Thanks. I think I’m gonna use the GN4 10w-40. It’s hot down here.
