MR33-102536
NEW 2025 - MR33 Silicone Differential Oil from our new premium supplier from Europe!
The differential oil from MR33 is graded in the most important steps between 1000cSt and 2,000,000cSt.
The new diff oil from MR33 enables the best possible setup for almost any RC car on a wide variety of race tracks and surfaces!
Content per bottle: 75 ml MR33 Differential Oil
Pro tip: "The viscosity of the oil in your differential is responsible for its effect. The differential allows the wheels on each axle to turn at different speeds. This is particularly important when cornering, but also when accelerating out of corners. A softer or harder diff can make a big difference depending on the track conditions. Sometimes your car only turns from a "good" to a "perfect" car with a different oil in the differential! "
In the cone differential, the silicone oil ensures how much the wheels on an axle can spin against each other (e.g. when cornering, when the inside wheel has to turn slower than the outside wheel).
Thin oil → easy spinning, thick oil → locked effect (less differentiation).
| Thin oil (e.g. 1000-3000 cSt) | Thick oil (e.g. 5000-100000 cSt or even putty style/locking diff) |
|---|---|
| Diff works more freely, wheels turn more easily against each other | Diff locks more strongly, both wheels turn almost equally fast |
| Better turn-in behavior, car is more agile | More traction on both wheels simultaneously, more stable when accelerating out of corners |
| Better for smooth or narrow tracks (e.g. carpet, technical tracks) | Better for high-grip tracks or tracks with lots of fast corners and acceleration zones |
| Less stability when accelerating out of corners | More "push" out of the corner, more stable on the straight |
With diff oil, you control whether your car turns in more, accelerates more stably or gets through fast or technical sections better.
Thick oil → locking effect → more propulsion/stability, thin oil → freewheeling → more maneuverability.
