Questions & Answers
Is this a genuine original part?
This is a premium quality aftermarket replacement part, manufactured to meet or exceed original equipment (OE) standards for fitment and performance.
How do I know if it is compatible?
We recommend checking the SKU/MPN and Cross Reference list provided above. If your original engine manual specifies 10W-30 FC-W oil, this is the correct product.
Can I use standard automotive 10W30 instead?
No. Automotive oils are not designed for the constant high-RPM loads or the moisture-rich, salty environments of marine use. This FC-W certified oil includes specific additives to prevent corrosion and oil film breakdown that automotive oils lack.
Note: Please verify your engine's oil capacity and viscosity requirements in your owner's manual before purchasing. 4Boats UK delivers high-quality marine maintenance solutions nationwide.
