Best oil

[greenglowSER]

I just got a '98 sportster 1800 my first boat ever. My Uncle who has been boating as long as I can remember and said that the motor looks like one of the best he has seen. All new plugs, battery, and wires, with a "tune up" done in may. When it comse time to add oil and change out plugs dose anyone have any recomendations?

Here is the information on the AMSOIL Interceptor Oil. http://www.amsoil.com/storefront/ait.aspx?zo=367509
Prices listed are Retail. For a Preferred Customer Pricing EM, PM or call me.
I think this engine is the 2-stroke and calls for a API-TC oil. Correct me if I am wrong on the engine.

I'd recommend BRP oil and you know you're safe.

If your engine calls for 10W-40 I would say that the Mobil 1 Racing 4T 10W-40 Oil would be the way to go if you want to run synthetic. I run this in my Sea doo 4-Tec N/A Engine and it stays cleaner longer then conventional oil. It also helps keep the oil temp down. But make sure what viscosity(weight) oil your suposed to run in that engine before you change it becuase i'm not familar with that engine.
