This issue of the Distributor Magazine highlights key performance advantages across several product categories, led by a deep dive into Signature Series motor oil and volatility performance. Beginning on page 8, the article explains how the NOACK Volatility Test measures oil evaporation under extreme heat and why this matters in real-world driving. AMSOIL Signature Series delivers a 7.2% result versus the 15% industry limit, meaning better resistance to evaporation, reduced oil consumption, fewer top-offs, and cleaner engine operation over time. The takeaway for customers is simple: stronger volatility control leads directly to longer-lasting protection and more consistent performance in demanding conditions.

The Tech Talk section on page 7 reinforces how modern engine protection is achieved, especially as low-viscosity oils become more common. Rather than relying on thickness alone, protection comes from a combination of viscosity, base oil quality, additive chemistry, and mechanical design. This is especially important following recent industry discussions around low-viscosity oils. AMSOIL Signature Series is positioned as a solution that delivers strong film strength, wear protection, and engine cleanliness even at lower viscosities, helping distributors address common customer concerns about thinner oils.

On pages 10-11, the magazine shifts to drivetrain performance with a focus on thermal runaway in differentials. Under heavy load and heat, gear oil can break down, leading to a destructive cycle of increased friction and temperature. AMSOIL SEVERE GEAR® is designed to interrupt this cycle by maintaining viscosity, resisting oxidation, and protecting against wear through advanced additives. The key message is that managing heat proactively helps prevent costly failures and extends component life, especially in trucks and severe-duty applications.

Brake systems are covered on page 12, where the article emphasizes that brake fluid is often overlooked but critical to safety. Over time, moisture contamination lowers boiling points and increases the risk of brake fade and corrosion. AMSOIL DOT 3 & 4 Synthetic Brake Fluid is highlighted for exceeding minimum standards, maintaining high boiling points even with water contamination, and delivering consistent braking performance. The article reinforces a simple maintenance message for customers: replacing brake fluid regularly helps maintain safety and avoid long-term system damage.
