Choose Rock Oil Engine Oils for enhanced engine care, reduced maintenance needs, and lasting quality that keeps your vehicles and equipment in top form.
Rock Oil stocks mineral oils (e.g., AGRI-GUARD® 15W40) and synthetic oils (e.g., STRATA SS 5W30 and Synthesis F 5W-30) in its product range. Synthetic oils provide better performance at low and high temperatures, better engine protection, better fuel economy, and longer life compared to mineral oils, which provide good value for normal service conditions.
Rock Oil is concerned with the environment. Rock Oil products like Groundsman 4 Stroke Engine Oil and One Shot 2-Stroke Oil are formulated to reduce emissions and environmental strain without affecting performance.
We would not recommend mixing various oil formulations since this will reduce the gain in performance. Each Rock Oil product is formulated for a specific application and set of operating conditions.
Although Rock Oil products last for years, we typically suggest that you stick to your manufacturer’s recommended oil change interval. For farming apparatus with AGRI-GUARD® 15W40, it is typically every 250-300 hours, while with cars using STRATA SS 5W30, 10,000+ miles is achievable between changes.
