Reverse gearbox oil


BOM

Recommended Posts

Can anyone recommend an oil that has worked well in their reverse gearbox? The factory has stipulated E.P. 80 or 90, but no specific brand. Has anyone tried a part synthetic lubricant such as Castrol 75-90 ?

Reverse boxes have a high tendency to blow up and need warranty work, so if you use a different oil from the factory recommendation you could be landing yourself with trouble if they get wind of it when there are warranty issues.

Most bike engined cars I know run Redline Shockproof (Heavyweight) Gear Oil. It has a 250W viscosity rating so copes with the heat much better than EP90. Fully Synth. Can get it thru Demon Tweeks.

Reverse boxes and their oil are nothing but trouble!

Stick with a quality oil but don't go mad, the blessed thing slowly blows it out anyway  :devil:

Comma or Castrol is just fine for the length of time it's going to stay in there... doh...
