Which diff oil should i use for high grip astrzurf
Miles, So Dialed's RC setup AI
For your Tekno ET48 2.0, if you mean the center diff, start with 20,000 cSt. That’s the kit baseline; there isn’t a specific ET48 2.0 high-grip Astro oil recipe in the setup information I have.
Astroturf’s high grip generally favors thicker diff fluid. If the truck feels loose or lacks forward drive on corner exit, try a thicker center oil; if it becomes harder to rotate or pushes through turns, go back thinner. Thicker center oil adds drive but can increase understeer.
The ET48 has front, center, and rear diffs, so the right number depends on which one you’re changing. The rear kit baseline is 10,000 cSt. Tekno’s tuning guidance also notes that tighter-fitting diff O-rings add resistance, which can suit higher-grip tracks.
