Doc's Auto Parts Windshield Washer Super Concentrate

Doc’s Auto Parts Windshield Washer Super Concentrate: One 16 oz bottle makes up to 4 gallons of washer fluid. That replaces four full gallon jugs of pre-mixed fluid with a bottle that fits in your glovebox. A $4 jug at the parts store is 98% water, and there is no reason to pay to ship it or haul it home.  Unlike pre-mixed fluid that locks you into one protection level, Doc's Super Concentrate lets you dial in exactly what the season demands. Mix at full dilution for warm-weather bug season and get the maximum 4 gallon yield, or step up the concentration to protect your washer reservoir and lines down to -40°F. You get six protection levels from one bottle, and the dilution chart on the label makes mixing a 30 second job. The concentrated formula breaks surface tension to cut through bugs, road grime, oil film, and road spray, leaving glass streak-free on every wipe. It is also fully rain-sensor safe and compatible with ADAS cameras, optical rain sensors, and Lane Keep Assist, so it works on late-model trucks and passenger vehicles alike. Product Details: One 16 fl oz (473 mL) bottle makes up to 4 gallons of washer fluid at the 60°F dilution, replacing four gallon jugs of pre-mixed fluid at a fraction of the cost per gallon. Freeze protection is adjustable from 60°F everyday driving down to -40°F arctic conditions, with six protection levels shown on the bottle's dilution chart. Increasing the concentration as temperatures drop prevents washer reservoir and line freeze-up on cold mornings. The formula removes bugs, road grime, oil film, and dirt from automotive and heavy-duty diesel windshields. It breaks surface tension for streak-free, film-free glass on every wipe. The fluid is rain-sensor safe and compatible with ADAS cameras, optical rain sensors, and Lane Keep Assist systems. It is safe for rubber lines, plastic reservoirs, and all vehicle washer systems. The concentrate format allows compliant mixing ratios for regulated areas, including California Type A and Non-Type A requirements. It is suitable for automotive, diesel pickup, fleet, and heavy-duty equipment use. Store and transport in a closed, upright position so it's always ready when you need it. Mixing + Directions: Mix to the ratio for your season using the dilution chart on the bottle, then top off your reservoir. Check the coldest temperature you expect this season and find your ratio on the dilution chart. Mix the concentrate with clean water at that ratio. Warmer weather uses less concentrate and yields more fluid per bottle, while colder weather uses more concentrate for freeze protection. Clean any dirt from around the washer reservoir cap, remove the cap, and fill. Follow your vehicle manufacturer's recommendations. Before winter arrives, run a stronger winter mix through the system so the lines and nozzles are protected along with the reservoir. Keep the bottle tightly closed and store it away from children and pets. Do not accept the bottle if the inner seal is missing, loose, broken, or punctured. Doc's Part Number: DDWFL16OZ
