ACDelco GM Original Equipment 1051515 Optikleen Windshield Washer Solvent Concentrate - 32 oz

Dilutes into a full replacement of Bolt EV's tank. Works fine; low streaks.

Don't make the mistake of adding too much of this stuff... especially in a state that regulates the concentration ratio of washer fluid. It goes a long way!If you were to follow the instructions and use 1 gallon of distilled water for each fillup, you could get over 5 summer blend uses out of 1 bottle. That's huge value. Or 2 winter blends and 1 summer blend. Depends on your usage and ambient temp + time of year. Obviously best value during summer.10/10 and like others I love the smell. The premixed blue gallons sold at the parts store always have a candy-like odor to them which in some settings smells a little like a honey bucket to me lol. This stuff... smells like new car. No fruitiness or sweetness.

Love this stuff, even though it's on the expensive side. Cleans all the big guts or road salt off my window with less solution needed than other brands. Also love that minty fresh smell you get when you use it. Strangely, in the bottle it doesn't have a smell, but when it gets sprayed you'll smell it if you have your fan running.

I just thought I way buying 2 Gallons because that's what the photos of the product was. 1 gallon bottles and I needed 2 gallons.I have no problem mixing, I have an almost empty 1 gallon windshield washer solution now.I do like the mixture chart because I'm from New England and I remember when the solution would freeze in the lines. When I started driving legally at 16, even though I am a V8 gearhead. I bought a 1969 VW Beetle 4 speed stick. I had $800 bucks for a car and minimum wage jumped from $1.95 to $2.10 per hour. Gasoline was .50-.55 cents per gallon. Plus I ran 4 studded snow tires, that car went anywhere.The windshield washer solution was fed by air pressure from the spare tire. You constantly added air to the spare, plus there was no fan for heat and defrosting the windshield. I had a flat scraper for Inside to clear ice.I just added 90% rubbing alcohol into what existed back then.Obviously this AC Delco product handles that as other modern solution for cold areas.You must realize that in the 1960s and almost until 1980 we had no idea how much damage we caused to the environment. I certainly didn't think adding rubbing alcohol was a bad thing to do.Recently, the "experts" have issued warning about any windshield washer solution.I'll be long gone before it's a problem, but perhaps younger people will be more sensitive to what's happened.I write lengthy reviews, generally because most people have zero understanding about automotive chemicals.

This stuff smells great and works so good!! It’s definitely worth the buy!!

Why did you pick this product vs others?:This is the best!

In order to use in cold weather, It's a 50/50 dilution. 9 dollars for 2quarts of fluid. No thanks!

Thus product is non-scented. Was hoping to find the scented washer fluid that came with the vehicle when new.
