Fluids are the lifeblood of an engine...

We manufacture private label products for many leading brands, and offer our own premium brand, NO-ROSION, direct to consumers like you.

Our coolant additives prevent corrosion, deposits, electrolysis, pump failure, and overheating. They can be used in any coolant, and provide 100% protection. Even in straight water.

And our fuel additives prevent corrosion, deposits, detonation, power loss, valve seat recession, and piston damage. They can be used in any fuel, and provide stabilization, clean-up, and octane enhancement.

We have over 50 years experience in industrial specialty chemicals, and 28 years experience in automotive coolant and fuel technologies.

Our mission is to assist your maintenance efforts by providing the absolute highest quality engine fluid additives available.

This is why our customers are collectors of some of the finest cars in the world.
