Formula 4-Stroke® Marine is Now FC-W Catalyst Compatible

To help reduce emissions, some four-stroke marine engines are now equipped with exhaust aftertreatment devices. To stay on top of this latest technology, AMSOIL recently upgraded the Formula 4-Stroke Marine Synthetic Motor Oil (WCT, WCF) formulation to make it catalyst compatible. Its packaging now includes the new FC-W Catalyst Compatible logo and corresponding certification number (FC-00358P [WCT], FC-00357P [WCF]). The formulation is backward-compatible, continuing to provide outstanding protection where FC-W oils are recommended. Formula 4-Stroke Marine Oil now also meets API SM qualifications. Its pricing remains unchanged.
