Green by Design. Tough by Nature!
The CEC L-33-T-82 test is the global standard for oil biodegradability. NHOU® ENVIRO™ not only passed—it exceeded all benchmarks, including those simulating marine exposure. Made from bio-based ingredients, it showed no immediate or long-term environmental impact.
Clean Chemistry. Proven Protection
Built for Vehicles. Trusted on Water. Proven in the Field.
As a non-toxic, non-hazardous, bio-based, and biodegradable formula, NHOU® ENVIRO™ is ideal for vehicles operating near coasts, lakes, or rivers—as well as boats, trailers, and tow vehicles.
