Anyone know what weight diff fluid comes standard in the Ofna Hyper Sprint??? My diffs seem to need more fluid and was wondering what to use.....Thanks..

Here is a link to the manual. It should specify what oils to use.

A lot of RTR's come stock with grease in the diff. As far as what diff oil to put in with a rebuild of the diff depends on the surface you are on.

Here's a link to resources related to the Losi L8ight Model. Not the same car obviously, but it's dirt oval, so it should provide you with a decent starting point for what diff oil to use:

Another place to look is the Dirt Oval section on RCTech. That forum will probably be much more help.

Spoke with Ofna today and they said the stock diff fluid in all three diffs is #3000..Hope that will help someone else having the same issues. All three diffs in my car were pretty much out of diff fluid.
