What Rislone does

Rislone is a US-based, privately held automotive chemical additive manufacturer founded in 1921 and headquartered in Holly, Michigan. The company engineers and sells a broad portfolio of vehicle performance chemicals spanning seven categories: appearance, cooling system, diesel exhaust fluid (DEF/SCR), engine, transmission, fuel system, and power steering. Its underlying technology is built on proprietary chemical formulations including polyetheramine (PEA) detergent technology for fuel system cleaning, zinc dialkyldithiophosphate (ZDDP) anti-wear additives for older and high-performance engines, high cloud point surfactants for coolant wetting, and "Xtreme Lube" engine lubrication technology. The catalog is anchored by trademarked sub-brands such as Hy-per Cool, Hy-per Fuel, Hy-per Lube, Cat Complete, Ring Seal, DEF Crystal Clean, DPF Clean, and Splatt, with multiple products carrying third-party validation including a PTEN Innovation Award.

The company's go-to-market is a multi-channel distribution model that relies on shelf placement at all major US auto parts chains (Advance Auto Parts, AutoZone, O'Reilly Auto Parts, NAPA), mass retailers (Walmart, Meijer, Menards), Amazon, its own e-commerce storefront, and a network of regional distributors covering 50+ countries across North America, Latin America, Europe, Africa, and Asia Pacific. Pricing is unit-based at the consumer level (most SKUs $15–40 per bottle) with larger super-concentrate SKUs sized for fleet and commercial applications; the company also runs $5–$15 rebate promotions on select products through December 31, 2026. Customer segments are diverse and horizontal: individual DIY vehicle owners, professional mechanics and shops, high-mileage vehicle owners, performance and racing enthusiasts, and diesel pickup/SUV/commercial vehicle owners. Revenue is generated through one-time consumer product sales rather than subscription or recurring contracts.
