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.
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?
