bud was using RP MT oil in his b18c for a good year, tracked it a few times, drove hard all over the shop, various conditions, besides the hexy price, it did a good job

OEM only!!! (pretty much).

None of this motul / fully sick (not so) high performance stuff.

Depends on what the gearbox characteristics are. I know the Renault boxes I was used to as a young bloke only took single grade 80w oil as any multigrade stuffed them within a week. Why? Who knows.
Don't necessarily go OEM, just stick to the manufacturers recommended grades and if the shifts are not so good find out about higher performance oils then.
redline is great but a little costly. Lucas additives are good for gearboxes too as is Nulon G70.

80w is way too heavy for a honda box.

They're designed to be used with oil that has similar weights to engine oil.

If oem didn't suit your box , then there is an issue that OTHER fluids were masking with thicker or additives. Oem is actually the best stuff for any Honda gearbox , short of a full blown race car and it's long hard working stresses.

i used OEM in my box and i tracked it twice without changing, still all good.

OEM ftw.

i used redline once in an ITR lsd box and it blew after 20kms. Literally had an apple sized hole in the bottom and destroyed gear set. Nothing like a driveway covered in g/box oil for some fun.
