Rio Stag Windshield Washer Fluid is specifically formulated for Tesla vehicles and compatible with all major car brands including Rivian, Toyota, Ford, Hyundai, and other EVs. Unlike most US washer fluids that use methanol—which can damage your paint and washer system—Rio Stag uses premium ethanol, the recommended choice in Tesla manuals. This ethanol-based formula is free of bug remover additives that can leave residue on your windshield, potentially causing phantom braking and sensor interference issues. Effective in temperatures from 0-10 degrees F, this American-made washer fluid comes in a convenient 1-gallon (3.78 L) container. Give your vehicle the proper care it deserves with a washer fluid that's truly better for your car's systems and performance.
