Suzuki Marine Outboard Oil

Suzuki ECSTAR is Suzuki's house brand of marine lubricants, formulated specifically for the tolerances, operating temperatures, and load profiles of DF series 4-stroke outboards. Using ECSTAR oil keeps your maintenance aligned with Suzuki's factory recommendations and is the oil used in Suzuki's own dealer service departments.

Boat Max Online stocks genuine Suzuki ECSTAR 4-stroke outboard oil in 10W-40, the viscosity Suzuki specifies for most current DF models, available by the quart and in case quantities for owners performing their own scheduled maintenance. ECSTAR marine oils are FC-W certified, meeting the NMMA standard for corrosion protection, shear stability, and additive performance required for marine 4-stroke engines; protection that automotive oils, lacking marine-specific corrosion inhibitors, do not guarantee.

As an authorized Suzuki Marine dealer, every bottle of ECSTAR oil we sell is genuine Suzuki product through authorized distribution. Free shipping on orders over $499 to the lower 48 states.
