RC Glossary

Diff Oil - Diff Fluid --

A silicone based fluid used in sealed diffs to tune the diff action. Diff oil is rated by weight (wt.), such as 1000 wt. (thinner) or 5000 wt. (thicker). Thicker oil creates more resistance to the diff action, while thinner oil allows the opposing tires to spin more freely. Using diff oil in a diff that isn't sealed almost always results in a mess. A good starting point for the diff oil in 1:8 buggies is 7000 / 5000 / 2000 (center / front / rear), while the bigger tires of truggies would require something closer to 2000 / 7000 / 3000 (center / front / rear).
