I use AMSOil in several other vehicles, and was wondering if any of you out there have been using it instead of Yamalube?
I'm curious, because I'd like to go to a full synthetic in my '16 F115, but have noticed that Yamalube marine full synth only comes in 5w-30, and I'd much prefer 10w-40 here in the mid-south heat. Here's what they say about their oil:
AMSOIL Synthetic Marine Engine Oil is a premium-quality synthetic formulation engineered for the harsh operating conditions of marine environments. It withstands the intense mechanical action of continuous, high-rpm operation to deliver superior viscosity protection. Synthetic Marine Engine Oil is specially fortified with a heavy treatment of advanced additives that protect motors against wear, rust and deposits. It excels in high-horsepower applications and all-day trolling conditions.
NMMA Certified
Synthetic Marine Engine Oil is certified by the National Marine Manufacturers Association (NMMA) for use in four-stroke outboard motors. This high-quality oil demonstrates outstanding performance and meets the NMMA FC-W Catalyst Compatible specification requirements.
Superior Protection Against Engine Wear
Marine engines operate under high loads and rpm for extended periods of time, causing traditional automotive oils to break down and lose viscosity. To ensure protection and long-term durability, the NMMA introduced the FC-W Catalyst Compatible standard, which is backward-compatible with the recognized requirements of the FC-W standard. AMSOIL Synthetic Marine Engine Oil meets the FC-W and FC-W Catalyst Compatible shear stability requirements, outperforming competitive oils to deliver a superior lubricating film. Formula 4-Stroke Synthetic Oil contains robust anti-wear additives that further reduce wear in metal-to-metal contact regions.
Excellent Anti-Rust Performance
Marine engines are prone to rust, leading to uncontrolled wear and premature engine failure. Good rust protection is not natural to motor oil; it comes only by design. Synthetic Marine Engine Oil is fortified with a special anti-rust agent, even more than required to pass stringent NMMA FC-W and FC-W Catalyst Compatible anti-rust testing.
APPLICATIONS
AMSOIL Synthetic Marine Engine Oil is recommended for gasoline-fueled four-stroke outboard, inboard, inboard/outboard (I/O) and personal watercraft motors. Use the appropriate viscosity grade where specified in the following:
Honda®, Mercury®, Yamaha®, Johnson®/Evinrude®, Bombardier/BRP®, Suzuki®, Nissan®, Tohatsu®, OMC®, Volvo Penta®, Mercruiser®, Chevrolet®, Ford®
NMMA FC-W Catalyst Compatible • API SM
I know this is probably a hotly debated topic, but I'd like to hear you all weigh in on this.
If you use Mobil 1 or something else, I'd be interested in hearing that as well.
Thanks in advance for your replies!
