What oil?????

Ok guys its time to add more oil to my reservoir tank. I have a '93 Mariner 150 EFI that ive own a couple yrs now and have never had to add any. I dont know what Ive been running since it was full when I bought it. Its a direct injection so theres no premixing. Im leaning toward Lucas SemiSynthetic Land and Sea


Anyone have any opinion on this oil or what do you use?

Any name brand oil will work. As long as it is rated TC-W3. About 50 years ago I was short on money so I bought a quart of K-Mart oil. Boy was that a mistake. It kept fouling the plugs.

Thank You sir
