I don't want to sound stupid, but all I have ever owned was OMC products. Can someone please tell me what is the correct type of oil to use in my motor? I have heard regular 2 cycle oil (Correctly rated) will be fine, but then again, I have heard you must use the Quicksilver stuff designed for Optimax (At $29.95 per gallon, it should work good!!!) to keep the warranty.
