DIY mechanics are at the heart of car culture, with gearheads all over the country putting hundreds of hours of work into projects in their home garages. Valvoline has created a new video series – “Under the Hood: The Spirit of DIY” – to bring the passion of DIYers everywhere to life. In each video, we’ll go behind the scenes and under the hood to see just what projects are hiding in garages, or flying down highways near you.
