AMSOIL has released a new motor oil for breaking-in new or rebuilt high performance and racing engines. New AMSOIL Break-In Oil (SAE 30) is formulated without friction modifiers to safely and effectively hasten the break-in process. While it is designed to seat rings quickly, engine protection has not been compromised. To protect the flat tappet cams that are present in many of these types of engines, this oil has a high zinc and phosphorus content. It also maintains a strong film strength to prevent metal-to-metal contact. New “BRK” Break-In Oil is available in single quart bottles or cases of 12.
