AeroShell Oil 100 Break-In is an SAE 50 straight mineral aviation piston engine oil specifically formulated for use during the break-in of newly rebuilt or overhauled engines. Packaged in a 6 x 1-quart case, it is ideal for private owners and maintenance teams that need convenient quantities for proper engine conditioning.

Unlike dispersant oils, AeroShell 100 Break-In is blended without additives that would inhibit controlled wear. This allows piston rings and cylinder walls to seat properly, prevents glazing, and ensures stable compression after the break-in process.
