Aftermarket Gearbox oil for Honda B20 Manual Gearbox?

Post by ThatBloke »

Does anyone know of good quality aftermarket Gearbox oil that can be used in a manual gearbox on a Honda B20 engine?

Honda MTF is obviously the recommended oil by Honda but at almost R350/L there may be cheaper options that work just as well. I would normally use Honda MTF but I'm also troubleshooting the gearbox, the current oil is still factory oil 18yrs old so I want to try see if an oil change will help with shifting but I don't want to spend R700 on oil only for it to be chucked away because the gearbox needs to be opened.

Thanks Missioner, have you personally tried it before in a Honda manual gearbox?

Does anyone sell redline gearbox oils in Sa?

Castrol used to have an online oil guide for various gearboxes. They also make generic oils for certain applications, e.g. transaxles.

To my mind, when matching specs, the most important things to get right, are
... the type of gearbox (e.g. transaxle)
... the viscosity specs (e.g. SAE 70W-90 as opposed to e.g. SAE 80)
... lubricity / extreme-pressure-additive specs (e.g. API GL-4 vs. G-5).
