    Northwind FC-W Full-Synthetic Marine Engine Oil 10W-40 (1 gal)

    COM-PRO-00764
    NMMA FC-W full-synthetic 10W-40 four-stroke marine engine oil, one-gallon jug
    25 In stock

    Overview

    Marine four-strokes do not live the life a car engine lives: long hours at high load, salt air in the crankcase breather, months laid up between runs. This full-synthetic 10W-40 is blended and NMMA FC-W certified for exactly that duty, with a shear-stable additive package that holds film strength at wide-open throttle and corrosion inhibitors that protect bare steel through a winter on the hard. It resists the emulsification that turns neglected oil the colour of coffee, drains clean at the next service, and carries the detergency to keep ring lands and valve gear free of varnish. One US gallon, sized for a twin-engine oil change with a margin for the filter.

    Warranty-safe genuine parts

    Scheduled service plans, genuine-parts kits and a hull record that stays with the vessel for its whole working life.

    Ordering & dealer support

    Do you offer discounts for large orders?

    Yes. Dealer-net pricing is tiered by annual volume and is applied automatically at checkout once you are signed in. Orders over $2,500 ship freight-free inside the Gulf Coast network. Ask your account manager about programme pricing on stocking orders.

    Unused parts in original packaging may be returned within 90 days against the original order number. Electrical components and special-order items are non-returnable once fitted. Start a return from Order history and an RMA number is issued the same working day.

    There is no minimum order value for stocked parts. Some consumables — impellers, anodes and filters — are supplied in trade packs, and the pack size is shown on the product page.

    Yes. Dealer-branded labelling and pre-assembled service kits are available on request for repeat orders. A bill-of-materials kit can be saved to your account and reordered as a single line.

    Stocked parts ordered before 15:00 CT ship the same working day. Larger propulsion and drive assemblies ship in 2 to 3 working days. Tracking is posted to your account and emailed to your ordering contact.
