This anti-freeze is just as good as any name brand and the price is hard to beat. I buy the concentrate and then mix it 50/50 with water to get 2 gallons which is much cheaper than buying 2 gallons of ready mix.

It keeps my car, running nice and cool in the summer during the hottest days and prevents my car from freezing during the coldest days. Year-round protection is what you get here for a bargain price no need to overpay for the namebrand.
