Oil 25W-40 Synthetic Blend 4L – code: 92-8M0086227 – Mercury

25W-40 Synthetic Blend Oil 4L Mercury (code 92-8M0086227)

The’25W-40 Synthetic Blend Oil Mercury in packaging 4L (code 92-8M0086227) is an engine oil for marine applications designed for use on 4-stroke outboard engines. The formulation synthetic blend (synthetic blend) is developed to meet the typical needs of nautical use, where the protection of internal components and the continuity of lubrication are central aspects in routine maintenance.

It is suitable for outboard motors that require oil SAE 25W-40 with specification FC-W oil and is offered as a solution for general use. The product is also recommended for use in Verado engines and can be used in all 4-stroke engines when the specifications required by the manufacturer correspond to those listed.

Main features and details

Synthetic Blend formulation for marine use

It is a synthetic engine oil blend developed and produced to meet the usage requirements in 4-stroke outboard engines. Choosing a specific oil for the marine sector helps maintain consistent performance under typical boat operating conditions, where the engine may run for extended periods and in potentially harsh environments.

Viscosity and specification

• Viscosity: 25W-40
• Quality / specification: FC-W

For correct selection, it is always good practice to check what is indicated in the engine manual or manufacturer’s specifications, especially if there are particular requirements related to the model or year of production.

Protection and lubrication of internal components

The product description highlights a targeted lubrication of internal components of the engine, with the aim of helping to reduce phenomena of wear, abrasion and scratches in moving parts. In maintenance, an appropriate oil is a key element to preserve over time the smooth operation and internal cleanliness of the engine.

It is also indicated that the oil reduces the coatings of the piston rings, an aspect that falls within the management of deposits and the care of internal surfaces subject to continuous work.

Protection from internal corrosion

For marine engines, protection from internal corrosion is a recurring theme: the nautical environment can promote the presence of moisture and conditions that require lubricants designed for this context. This oil is presented as oriented towards protection against internal corrosion for marine engines.

Recommended applications

4-stroke outboard engines

The oil is recommended for all 4-stroke outboards that require an oil SAE 25W-40 FC-W. This makes it suitable as a maintenance choice for many 4-stroke engine configurations, provided the required specifications match.

Recommended use on Verado

The product is indicated as oil recommended for use in Verado engines. In case of doubts about compatibility or required specifications, it is advisable to follow the manufacturer's instructions and the prescriptions reported in the engine manual.

General use

It is described as recommended for general use. In the nautical field, this means it can be considered for routine maintenance when a multigrade oil with FC-W specification is desired, suitable for the typical needs of 4-stroke outboards.

Maintenance advantages (from a professional perspective)

Targeted choice for the nautical sector

Using an oil designed for marine engines helps maintain a more consistent maintenance management, especially when operating on boats that work under variable conditions and with different usage cycles compared to the automotive sector.

Support for the protection of moving parts

The formulation is presented with a focus on protection of internal components and on reducing wear and abrasion phenomena. This approach is particularly useful in the workshop or storage, where the choice of lubricant affects the quality of the intervention and the continuity of engine operation between services.

Deposit management and care of piston rings

The note regarding the reduction of piston ring coatings draws attention to cleaning and deposit control: important aspects to maintain smooth operation over time and reduce the need for corrective interventions related to encrustations or residues.

Protection from internal corrosion

In a marine environment, corrosion protection is a recurring requirement. This oil is described as oriented towards a protection against internal corrosion, useful as part of a maintenance strategy that also includes periodic checks, proper storage, and storage procedures.

Usage and operational notes

Check specifications before use

Before use, verify that the engine requires:

• Viscosity 25W-40
• FC-W specifications

In the presence of specific manufacturer indications (for example, for certain series or configurations), always follow the user and maintenance manual.

Good maintenance practices

• Use clean and properly stored oil, avoiding contamination during topping up.
• Follow the maintenance intervals provided by the engine manufacturer.
• In case of replacement, properly manage the disposal of used oil according to local regulations.

Note on names and codes

For orders and assistance, refer to the code 92-8M0086227. This facilitates product identification within spare parts catalogs and procurement procedures.
