Common questions about Rhodex products, viscosity selection, application, and ordering. Can't find your answer? Contact us.
Rhodex is specifically engineered for RC racing applications, not repurposed industrial lubricants. Every product is purpose-built — our shock oils are heat-stabilized for racing thermal loads, our greases are matched to specific component materials, and our Heliox line uses aerospace-grade PFPE chemistry. Plus, every Rhodex product is manufactured in Britain to consistent quality standards.
All Rhodex RC Line products are formulated and manufactured in the United Kingdom. Our British manufacturing means we control quality at the source, ensure batch-to-batch consistency, and maintain tight specification tolerances.
Rhodex Silicone Performance Fluid is the top-ranked product in Amazon's RC silicone shock oil category. The bestseller status is based on actual sales rankings within the relevant Amazon category — it's earned through customer purchases, not paid placement.
56 specialist products across six categories: 20 silicone shock oils (50-1000 cSt), 14 differential oils (2,000-100,000 cSt), 12 specialist greases, 4 Heliox aerospace products, 3 specialty formulas, and 2 curated kits.
cSt (centistokes) is a precise SI viscosity measurement. WT (weight) is older RC hobby terminology. Approximate conversion: cSt ÷ 10 ≈ WT. So 350 cSt is approximately 35WT. However, different brands use slightly different conversions, so always reference cSt — it's the actual physical measurement. See our Viscosity Guide for a complete conversion table.
Three factors: vehicle scale (smaller RCs use lighter oils), track surface (smoother tracks need lighter oils), and driving style (aggressive drivers prefer firmer oils). For 1/10 touring cars, 200-400 cSt is typical. For 1/10 buggies, 300-500 cSt. For 1/8 vehicles, 400-700 cSt. Read our complete viscosity guide for detailed selection.
Yes — Rhodex Silicone Performance Fluid is fully blendable. Equal parts of two viscosities give you approximately the average. For example, 50% × 350 cSt + 50% × 450 cSt ≈ 400 cSt. Note: blending behavior is non-linear at viscosity extremes, so for racing precision, use the closest standard viscosity rather than custom blends when possible.
Use Rhodex Plastic Gear Grease, which is specifically formulated to be plastic-safe. Many petroleum-based greases attack plastic — causing swelling, softening, or cracking over time. Plastic Gear Grease is silicone-based and won't degrade nylon or polymer gears.
They're used together in ball differentials but serve different functions. Ball Diff Grease coats the diff balls and rings, providing controlled-grip behavior. Moly Thrust Grease (with MoS₂ extreme pressure additive) goes on the thrust assembly, handling the axial load forces. Use both — they're a system designed to work together.
Heliox is engineered for the most demanding applications — high-RPM ceramic bearings, severe-load drivetrain components, and applications where conventional lubricants degrade or oxidize. For standard racing applications, regular Rhodex greases work excellently. Reserve Heliox for components where its unique properties (chemical inertness, extreme temperature stability, no oxidation) justify the premium cost. See our PFPE Technology guide for details.
Yes. Rhodex Silicone Performance Fluid is 100% pure silicone with no PAO or mineral oil contamination. Pure silicone is compatible with all standard shock seal materials, including nitrile, EPDM, and silicone O-rings. It will not swell or degrade rubber seals.
For shock oils: yes, mixing silicone shock oils from different brands is generally fine, though you'll get the most predictable behavior with a clean fill. For greases: clean components first, especially when transitioning between different grease bases (PFPE, silicone, lithium). Mixing incompatible grease chemistries can cause separation or performance loss.
Less than you think. Over-greasing is the most common application mistake — excess grease creates drag, attracts dust and debris, and can slow components down. A thin, even coating is what you want. For bearings, a small amount worked into the balls is sufficient. For gear teeth, a thin film on the contact surfaces.
For racing: replace shock oil every few race weekends or when performance changes. Replace diff oil every 5-10 race weekends. For bashing/casual use: every 20-30 hours of run time. Always replace after a major impact or any visible contamination.
All shock oils thin out as they heat up — that's physics. The question is by how much. Generic shock oils suffer significant viscosity fade during racing. Rhodex Silicone Performance Fluid is heat-stabilized to minimize this effect, so your 400 cSt at room temperature stays close to 400 cSt at race temperature.
