Companies that have been around for that long are usually those that make really great products that their customers love.

As mentioned earlier, Valvoline is also the maker of Zerex coolants but its coolant brand has also gained massive recognition due to the quality of its products.

Rather, its coolants are made up of the same basic propylene glycol, eliminating the issues that are common with water-based coolants. Plus, the coolants are non-toxic and cause no harm if wrongly ingested since the active ingredient is used as a sweetener in many products.

Furthermore, the Evans coolants provide a superior form of engine protection as they prevent voids and corrosion due to the absence of water, allowing for a longer and healthier engine.
