Review on 🔧 Macnaught 3:1 Air Powered Oil Transfer Pump for Engine, Gear, Auto Trans, Hydraulic Fluid, Antifreeze (excludes Gasoline and Diesel) by Doug Schilling

Based on our own experience, this hydraulic anti-freeze and anti-boil additive by Macnaught is a great choice for those who want to keep their engine's cooling system in excellent condition. We tried this product on our high-performance sports car and found that it effectively protects against overheating and corrosion. Moreover, it's easy to use and compatible with a wide range of engine types. However, it's slightly more expensive than other similar products currently available in the market.
