what diff oil for RCM V3 hybrids??

[shizzon]

I purchased some traxxas 50k diff lube prior to looking at the V3 building instructions that recommend oils quite a bit thinner for both front and rear (7-10k front and 3-5k rear iirc). I don't plan on racing, just bashing, so will 50k front and rear handle ok? this is what is in my current diffs (stock traxxas) but im not sure if it will change with the RCM V3 diffs.

Thanks!
