Verdict

If you’re looking for the *right* antifreeze for your North American vehicle, and can handle the *current* price trend, the PEAK OET Extended Life Orange 50/50 Prediluted Antifreeze/Coolant delivers excellent quality and effective performance. However, make sure you're not in need of a HOAT formula, as this product is actually OAT.
