I have enjoyed using my ValvoMax system for many years.
Specifically I have noted both work & stress reduction/no wrench turning to perform an oil change after the ValvoMax is installed; Cleaner hands, no loose, hot, and oily plug in my oil changes anymore, no splattering of oil anymore.
Possible cross threading of my old drain plug in the oil pan is eliminated with this design.
The hose permits me to drain directly into a large bottle which eliminates the step of pouring from a drain pan into a waste oil container. This itself saves time.
---Fabulous idea.
---Elegant engineering.
---Highest quality CNC machining.
---The mechanical fits between individual components are exceptional.
