Oil Drain Intervals

During use, engine lubricating oil undergoes deterioration from combustion by-products and contamination by the engine. In addition, certain components in a lubricant additive package are designed to deplete with use. For these reasons, regardless of the oil formulation, regular oil drain intervals are required.

Note: The use of oil sampling and analysis to validate all drain intervals is highly recommended. To confirm oil drain intervals, use Detroit™ Genuine Oil Analysis kit, Part Number 23515823 .
