I run an 1/8 Inferno 7.5 platform, mainly for bashing but want to enter the racing scene. There are tons of conflicting suggestions on diff oils and would really like to narrow the field down even a little. Before we start, we can eliminate all talk about the importance of tuning to ones personal preference and specific characteristics of each vehicles build components - I GET IT! I race superbike, I am no stranger to having to fine-tune to ones personal style and equipment. I just want a smart starting point for both my nearly identical EV and Nitro models.

I run front 5000, center 7000, rear 3000. This was suggested to me by Kyosho tech support and I also found some evidence from possible racers in old posts. However...I find this to be a complete contradiction from more modern manuals like the NEO (that now finally have printed suggestions) of much much thicker oils all around. Furthermore, some have suggested in this site that this is a beginner tune to make it easier to drive, which actually contradicts the newer manuals which I am assuming are not printed for racers.

The reason I am struggling to find a diff fluid solution (individual equipment setup enters the picture) is because I am finding my EV buggy is wearing the front-end drivetrain twice as fast as my nitro buggy. In addition, the EV seems to turn much better on any terrain, I am thinking it could be related to the fast wear on the front - perhaps because it's pulling the front-end more rather than pushing. But why would the EV handle differently than an otherwise identically setup Nitro? - well I guess I just introduced 2 different questions rather than one I suppose.
