Straight 100 Grade, Mineral Break-In Oil
Straight 100 Grade Mineral Break-In Oil is formulated from the finest and purest petroleum base fluids and contain unique additive systems to improve performance and contribute to ideal engine break in. These oils are intended to break in new or refurbished aviation engines during the first 24 hours or less of operation. Note: these oils are NOT intended for normal operation. Instead, these oils allow for some friction to occur to ready the internal engine components for flight.
