Be careful where you get your washer solvent topped off. Many quick oil change facilities will use bulk concentrate and dilute it with water in order to maximize their usage. When temperatures get below freezing the diluted washer solvent can freeze too. This can cause a failure in your vehicle's washer solvent delivery system and can possibly damage this delivery system. Automotive Authority uses only bottled solvent that is never diluted and will not freeze until the temperature reaches -30F. Please call us with any questions.
