A little background: 1996 Suzuki, 4 cylinder, 90HP, oil injection, purchased new by me for a 17Ft. Alum boat. I ran the factory fill Suzuki oil until almost empty. I then removed the oil injection cannister from the engine and dumped any remaining oil. This is engine mounted and holds 5 quarts. I then filled with full synthetic Itasca. I ran Itasca oil until last year when I no longer could get it. I then purchased 4 gallons of another brand Full synthetic. I did the same routine of dumping out any remaining oil. This was 5/1/01.
Now for today and the ironic part. I had used 2 gallons since then and was on the full 3'rd bottle in the motor. Today, I decided to clean the fuel filter, and I have to remove the oil injection container. So it is easier to dump the oil into a gallon bottle for this. As I was pouring it in the gallon container it would be nice thin oil, then real heavy, slurry, then thin again. Had alot of residue in the bottle that looked like slime. This was NOT water or condensation, as 95 degrees over a week and no moisture on the cap. Needless to say I wasn't going to dump that oil back in. As luck had it, I had a case of 2cycle oil I had purchased for my 200HP EFI Mercury. So I put it in this one instead. It is semi-syn and contains moly and some other trade secret additive.
I called the oil company and they offered to replace any I had on hand. Just send it back in. I told him that yes I would do that and use it as a fuel additive in my diesel as it is ashless and the only thing I would trust it in. Not one question if my motor was still good ect. It had started to smoke like heck the last 2 times out, and was real low smoke before.
The moral of the story is that if you have an oil injection system on your boat, and it starts to run different, alot of smoke ect. I would check the injector oil first. Pour it in a container and check it.
