Excerpt: In our quest to keep the belt running smoothly, we tested the Treadmill Belt Lubricant, 100% Silicone 500CS, and were impressed by its high-temperature resistance and precision packaging. Unlike conventional oils that can break down under heat, our results show this silicone lubricant maintains stability even after extended use. The included application tubes and precision screw caps make dispensing a breeze, reducing messy cleanup. We appreciate the thoughtful design, which ensures consistent application every time. While silicone is generally more expensive than oil-based options, the longevity and performance make it a worthwhile investment. Our surprise find was its heat resistance—something we didn’t expect—suggesting it’s a great choice for high-intensity workouts. Overall, we’re satisfied with this lube’s reliability and precision-designed kit.
