I just quit using the Rotella this season. I'm running Amsoil 0W-40 now and love it. I always had a hard time finding neutral with the Rotella, but no issue now with the Amsoil.
On that recommendation I'd use Rotella if I could get it here. I have no problem finding neutral and would like to find it less often!
In case other UK riders would like to find neutral as often as I do, I use Putoline Light Gear Oil. Clutch action is good.
What are you guys paying for a gearbox full of oil? So for a litre I guess, I over full so I dont have 100ml of oil sitting around idle.
FYI, I pay 13NZD (10USD) for a 1L of Elf Moto Gearoil 10W-40
Or I can use Elf 4HP eco, 8NZD per L, which is a semi synthetic engine oil that all of the guys who I work with, MR Motorcycles, use in their 2 strokes, and 4 strokes.
I usually use Rotella but I have 2 qts of Hypoid Gear oil 80w90 kicking around.
Does anyone know if I could use this in the gearbox? I would think so but maybe some oil experts on here have an opinion.
