Our OEM partners expect quality, high performance and safety. When DGP certifies a formula, like DGP Pro100 Bar & Chain Oil, we are able to offer that formula to brands without retesting as long as there is no change to the formula. That choice is up to the OEM as new formulations take time, effort and significant cost to certify. The great DGP formulas you see in the market are promoted by some of the world's best brands to align with their retail strategies that correlate to their equipment and tools. DGP does not make equipment or tools, therefore having a DEWALT Bar & Chain Oil next to a DEWALT chainsaw makes obvious sense for a brand and retailer. The same DGP Bar & Chain Oil used by thousands of professionals that want the best cutting efficiency, lowest bar temps and certified awesomeness, is now available at select major retailers in Brands you love and trust. #changeyouroil, the future is green.
