    Consensus on Good Engine Oil for C180 215 HP SCIC

    Apologies but couldn't find previous thread ... saw some references to Amsoil 4-stroke synthetic marine oil 10W-40 ... saw other posters saying synthetics must be avoided for this SCIC engine.

    Thanks in advance. Dave

    Package sizes include:

    1-Quart Bottles (case of 12)
    55-Gallon Drum
    PRODUCT DESCRIPTION
    AMSOIL 10W-40 Formula 4-Stroke® Marine Synthetic Motor Oil (WCF) 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. Formula 4-Stroke® Marine Synthetic Motor Oil is specially fortified with a heavy treatment of advanced additives that protects motors against wear, rust and deposits. It excels in both high horsepower applications and all-day trolling conditions.
    4-Stroke Outboard Motor Warranty Certified
    Formula 4-Stroke® Marine Synthetic Motor Oil is certified by the National Marine Manufacturers Association (NMMA) for use in four-stroke outboard motors. This high quality oil demonstrates outstanding performance, exceeding the NMMA “FC-W” (Four Cycle-Water) specification requirements. Formula 4-Stroke® Marine Synthetic Motor Oil fulfills the warranty requirements of four-stroke outboard motor manufacturers.
    • NMMA Registration #FB-30010B 10W-40
    Superior Protection Against Engine Wear
    Marine engines operate under high loads and RPMs for extended periods of time, causing traditional automotive oils to break down and lose viscosity. To ensure good protection, the NMMA set minimum shear stability requirements for FC-W. AMSOIL Formula 4-Stroke® Marine Synthetic Motor Oil greatly exceeds the FC-W shear stability requirements, outperforming competitive oils to deliver a superior lubricating film. Formula 4-Stroke® Synthetic Oil also contains robust anti-wear additives that further reduce wear in metal-to-metal contact regions (see Four-Ball Wear Test graph).

    While automobile engines normally operate at around 2,500 rpm, outboard motors can run twice as fast, requiring greater levels of wear protection and better bearing durability than automobiles. In addition, prolonged idling and low operating temperatures contribute to fuel dilution, further thinning the oil. To ensure adequate protection for their engines, marine engine manufacturers set minimum high temperature/high shear (HTHS) viscosity limits. AMSOIL Formula 4-Stroke® Marine Synthetic Motor Oils are shear stable and formulated with sophisticated oil additive chemistry, exceeding the HTHS requirements of both the API and NMMA FC-W (see graph).
    Excellent Anti-Rust Performance
    Marine engines are prone to rust, leading to uncontrolled wear and premature engine failure. However, good rust protection is not natural to engine oil. It comes only by design. Formula 4-Stroke® Marine Synthetic Motor Oil is fortified with a special anti-rust agent, even more than required to pass stringent NMMA FC-W anti-rust testing.
    Applications
    AMSOIL Formula 4-Stroke® Marine Synthetic 10W-40 Motor Oil (WCF) is recommended for gasoline fueled four-stroke outboard, inboard, inboard/outboard (I/O) and personal watercraft motors. AMSOIL WCF motor oil is recommended for the following applications whenever an SAE 10W-40, 15W-40, 25W-40 or straight SAE 40 oil is called for:
    Four-stroke outboard motors: Honda®, Mercury®, Yamaha®, Johnson®/Evinrude®, Bombardier/BRP®, Suzuki®, Nissan®, Tohatsu®
    Inboard and I/O: Mercruiser®, Volvo Penta®, OMC®, Chrysler® Marine, Crusader®, Marine Power®, Chevrolet®, Ford®
    Personal Watercraft: Honda®, Yamaha®, Bombardier/BRP® (Sea-Doo®), Polaris®
    Note: AMSOIL Formula 4-Stroke® Marine Synthetic 10W-40 is recommended for use in place of 25W-40 as specified by Mercury®.
    NMMA FC-W • API SL

    Service Life
    Four-stroke outboard motors and personal watercraft applications: Due to potential fuel dilution or water contamination, change oil at the engine or watercraft manufacturer recommended interval.
    Inboard and I/O applications: Change oil at two times the engine manufacturer recommended interval or one year, whichever comes first.
    Mixing AMSOIL
    AMSOIL Formula 4-Stroke® Marine Synthetic Motor Oil is compatible with conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils will, however, shorten the oil life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.

    Aftermarket oil additives are not recommended for use with AMSOIL motor oils.
    Health & Safety
    This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS). MSDS’s are available upon request at 715-392-7101 or on our website. Keep Out of Reach of Children. Don’t pollute. Return used oil to collection centers.

    Stay with the OEM....not any more expensive, you'll get what the engine was designed to run with....i still run with the XPS 4 stroke oil 10W30 if i'm right...DO NOT USE any synthetic oil with the ones having the supercharger, you'll end up having a slippage in the supercharger clutch ass'y.

    You can run the AMSOIL 10w-40 Marine Oil in the Sea-Doo and not have any issues with the supercharger. There are a bunch of guys here that have run the Marine Oil and the 10w-40 motorcycle oil with the supercharged engines. Jerry to just name 1 http://www.amsoil.com/redirect.cgi?zo=367509&page=storefront/wcf

    Prices listed are Retail for Preferred Customer pricing PM, EM or Call me.

    I am amoung those that run the MCF 10W40. IMHO it`s way better, spins up faster, protects better from fuel dilution, I did an oil service a bit early and compared to BRP oil the Amsoil was absolutely marvelous! ...

    ballfire: do you have the metal washers in the SC? if not change them. That`s way more risky than whatever oil you choose!!!...PR...

    My C180 215HP SCIC yacht only has 2 hours on her (1 hour on the display) and I have done nothing other than pull my 2 kids in a tube.

    No metal washers ... where can I get them, easy DIY and any warranty implications?
    No 10 hour service until next year?

    U can get the metal washers at 4tecperformance, it's Jerry's store, as far as i'm concerned, i changed mine myself, but if you are not too much mechanically inclined, you can get someone else to do yours.....as far as the warranty goes....don't even tell anybody at your dealer, and they won't even know it's in there...and if so they might cancel the supercharger unit warranty....but shouldn't remove the rest of the boat warranty.

    My boats clutch was slipping from new (only pulling 7600rpm), had the washers changed at 6hr's (because of the fear factor!). Anybody can pull the charger out of a boat, after that just send it to Jerry since he will turn it around that day and send it back, while your at it have him put in the Green wheel (you WILL love it!), he charged me ~$75 for labor, thats not even an hour in the shop/rate.

    That's sounds like a viable option ... what's the total bill (perhaps Jerry can chime in if he sees this) for the washers and green wheel? BTW, what is a green wheel and the benefits?
