WS2 (Tungsten Disulfide) reduces the need for frequent oil changes and filter replacements by improving how well your engine oil performs. With WS2, less friction and heat are generated inside the engine, meaning the oil doesn’t break down as quickly. This keeps the oil cleaner and effective for longer, reducing how often you need to change it. By extending oil life, WS2 also reduces the amount of debris and contaminants that clog up your filters, so you’ll need fewer filter changes. In short, WS2 makes your oil last longer, saving you time and money on both oils and filters!
