Product Details

The Quicksilver 8M0169542 is a genuine OEM oil change kit designed specifically for 150–200HP Mercury L4 Verado 4-stroke outboard engines. Everything required for a complete, by-the-book oil service is included in a single, convenient package — no separate sourcing of filters, seals, or oil required.

At the heart of this kit is Quicksilver's industry-leading 25W-40 Marine Engine Oil, engineered under the exclusive Flagship Protection formula. Over five years of engineering and development went into this advanced formula, resulting in up to 33% better camshaft wear protection compared to competing marine oils, along with the highest levels of corrosion and oxidation protection available. The oil has also been proven to hold its viscosity ratings longer in industry wear testing — helping maintain consistent engine performance across extended service intervals.

Kit Contents:

  • 6 x 1-liter bottles of Quicksilver 25W-40 4-Stroke Marine Engine Oil
  • 1 x Genuine Quicksilver premium oil filter
  • 1 x Genuine OEM drain plug seal/washer
  • 1 x Mercury oil change instruction sheet

Key Benefits:

  • Resists oxidation and protects against varnish buildup and sludge formation
  • Exceeds NMMA FC-W rust protection certification requirements
  • NMMA FC-W and FC-W Catalyst Compatible certified
  • Meets or exceeds Mercury manufacturer warranty requirements — use will not void your warranty
  • Delivers outstanding wear and corrosion protection to help extend engine life
  • Maintains peak engine performance and long-term reliability

Quicksilver products are designed and validated by Mercury Marine — the same company that builds the engines these oils protect. Using genuine Quicksilver maintenance products ensures your L4 Verado outboard receives OEM-specified care every service interval.

In reading the reviews I was somewhat hesitant to use this company. But they came through exactly the way they said they would when they said they would do it. I can't ask for much more than that.
