The Howes Lubricator line of diesel and automotive additives is one of the oldest, most respected names in the additive industry. In 1920, Wendell V.C. Howes, the founder of Howes Lubricator Products, helped pioneer the automotive additive market with his line of preventive maintenance products. Having always kept abreast of the changing technology, Howes additives are the product of choice by many of America's largest fleets and thousands of repair shops nationwide. Howes Lubricator Products long running success is in part due to the endorsement from the professional trade, but also the Howes Guarantee Programs that back up America's oldest selling premium brand.
