When Underwood Synthetics was founded, we set out to provide the finest auto, heavy machinery and lubrication shop in the Hoodriver area. We stay at the forefront of the latest technology while retaining our knowledge of older classic cars. Whether your vehicle is old or new, we have the finest 100% synthetic oil standing by for any application you may have. 


We understand how important your car or truck is to you. We’ve built an unparalleled foundation of knowledge through rigorous training. It is our standard for each new team member to shadow more experienced members and learn the tricks of the trade only the most seasoned lubrication specialist would know. Our craft is our pride. Leave your car with pros who really care.
