Ensure the maximum lifespan and performance of your newly built or significantly repaired Duramax engine with the highly recommended Choate Engineering Performance Break-In Oil Kit. This kit contains the precise components needed for the critical break-in period for your Duramax engine.

• 3 Gallons Driven Break-In Oil (15W-40): A custom, high-zinc, petroleum, and low-detergent formula specifically designed to optimize engine break-in.
• 1 Oil Filter: The correct filter required for the first oil change on your Duramax engine.

Key Features:

• Minimizes Accelerated Wear: Specifically engineered to reduce wear and contamination during the initial stages of breaking in a new high-performance engine.
• Protects Crucial Components: The high zinc content provides better protection for cylinder walls, drive gears, oil pump parts, and camshafts. Choosing not to use a break-in oil sets your engine up for accelerated wear and potential failure.
• Controlled Friction for Rings: Unlike regular racing oils, break-in oil does not contain friction modifiers, which are sensitive to piston rings during seating.
• Prevents Break-In Failure: By tailoring the chemistry for the break-in application, this oil virtually eliminates the risk of component failure during the critical first 50 miles.
