AMSOIL BREAK-IN SAE 30 | Assembly & Break-In Engine Oil - 946ML

Protect your investment and guarantee a proper start for your fresh build with AMSOIL Break-In SAE 30 Engine Oil. Formulated specifically without traditional friction modifiers, this specialized fluid allows for the quick and efficient "controlled wear" necessary to perfectly seat piston rings against the cylinder walls. This crucial seating process seals the combustion chamber, preserves engine compression, and maximizes power output for the long haul.

Product Specifications :

• Brand: AMSOIL.

• Product Category: Assembly & Break-In Oil.

• Viscosity Grade: SAE 30 Monograde.

• Volume Capacity: 946ML.

• Country of Origin: United States of America (USA).

Product Benefits & Key Features :

• Piston Ring Seating: Omits friction modifiers to foster optimal ring-to-cylinder wall interaction, ensuring a fast, clean seal that stops blow-by.

• High-Level Anti-Wear Protection: Packed with zinc and phosphorus (ZDDP) additives to protect critical high-stress parts like flat-tappet camshaft lobes, lifters, and rockers during the early high-wear phase.

• Robust Film Strength: Utilizes high-quality base fluids with increased film strength to defend main bearings, rods, and journals from metal-to-metal contact under heavy loads.

• Engine Longevity Baseline: Correct initial break-in ensures excellent oil retention and maximum compression performance over the lifetime of the powertrain.

Usage Instructions & Recommendations :

1. Always follow the specific engine builder's step-by-step testing and break-in guidelines when available.

2. If custom builder recommendations are unavailable, the standard break-in period using this fluid should typically not exceed 1,000 miles before replacement.

3. Once the initial break-in phase is completed, drain the fluid thoroughly, change the oil filter, and transition to a premium AMSOIL fully synthetic motor oil.

Suitable For :

• Brand new crated engines, newly machined high-performance blocks, and rebuilt street/race engines—especially those utilizing flat-tappet configurations requiring heavy ZDDP protection.

Note:

This fluid is strictly engineered for short-term temporary engine break-in application. Do not utilize this product as a standard long-interval lubricant, and avoid blending it with fully synthetic oils until the break-in process is entirely completed.
