Hello all,

My son and I are expecting our 3racing gear diffs any time now. I've trawled through the posts on the board in search of what oil people are using in their diffs and it seems to be the 300-500k (I think gearbox oil rather than shock oil, I'm still quite new to RC racing).

They will be both running in M-05 chassis cars (long wheel base if it makes a difference). We have been racing at a local club here in the UK.

Any recommendations? I've got a few bottles of shock oil already available so it would be great if I could use that instead of purchasing more (I know the Spec R sealed diffs for the Schumacher Mi4 uses shock oil).

Thanks in advance for any recommendations.

Tony.
