Which outboard engine oil

Sleeto · #1 11-14-2004, 10:05 AM

Are some brands of outboard engine oil better than others? My Yamaha 250 requires TC W3. Does it matter which brand I use?

You can sit there and read for days. bottom line is that all oils are designed for specific engine brands. All oils are the same, except for the additives that are added to the oils. If you have Yamaha use Yama lube , Mercury use Quicksilver they are designed for those engines. Materials, engine designs, performance, injectors & carbs design are all factors in designing oil brands. It's worth paying more for quicksilver etc. over Lubrimatic trust me?

I concur. Used Yamalube in my old Yammie and still use it in my Suzuki because I dont really like the local Suzuki dealer and refuse to buy oil from him. If i had an Evinrude...I would run Evinrude oil.

Oh yeah..I always use Ring Free too...

Ran Yamalube in my Evinrude for years with no hiccups at all - it's what the marina sold, so it was easier.

Now I have a 4-stroke and am happy not to be subsidizing the oil companies quite as often [img]/images/graemlins/laugh.gif[/img]

The lubrication battle was won 50 years ago.. They all lubricate just fine, even the Wally World special.. The difference between OEM oils and say Exxon and Texaco is the amount of carbon inhibitor. Those 5.00 a gal oils might have 6-8% where OEM oil will have 15-25%. Carbon inhibitors are the most expensive additive.

As fas burning the same name brand oil as your engine...it doesn't matter one bit.. Yamalube has been a synthetic/dino mix since they started making it. Yam is the only one that didn't need to come out with a special oil for the DFI engines. DFI engines produce lots more heat in the crankcase because they don't have gallons of cool fuel passing through the crankcases, it get injected directly into the combustion chambers. If to are running a Yam HPDI, Merc Optimax or a Evinrude DFI make sure you are burning one of the oil specifically designed for DFI's. Mercs Optimax oil and Evinrudes XD-50 along with Yamalube synthetic/dino mixes made to handle this heat.. If you are running a DFI then stick with DFI oils. If you are not then stick with OEM oils made for non DFI engines like Evinrude XD-30 or Merc Premium Plus. Buy in bulk with your own containers and buy the cheapest OEM oil for whatever your brand engine is.. Your Merc will run just fine on Rude oil or Yamalube.. Becareful with Merc oils. Merc's Premium is made for outboard 70hp and less. Merc's Premium Plus is made for 70hp and up.. Make sure you know what you are buying if it's being pumped out of a 55 gal drum.

Doesn't matter what you burn all engines need decarboned both 2 and 4 stroke. I recommend 50-75hrs on 2 strokes and 100hrs for 4 strokes. They are all burning the same fuel and 60% of the carbon comes from the fuel not the oil..

Hi Dunk, I have a 225 OptiMax, Merc. recommends adding Quickleen (12 oz. per 72 gal. of gas). I've done this faithfully since I got the motor, which now has 150 hrs.Do I still need to do the periodic decarb?

Ed · #9 12-12-2004, 02:38 PM

I religiously run Yamalube and Ring Free in my Suzuki 225 EFI 2-stroke. With about 550hours I have not had any problems as of yet...knock on wood. Oh yeah...I also have a heck of a mechanic that takes care of my engine...Mr Scott Potter from Viking Marine in Portsmouth, RI. Definitely worth the annual long drive down from Newburyport, MA.

Dunk · #10 12-13-2004, 08:28 PM

Sec, yes you still need to decarbon...I don't recommend any additives if you deacrabon the engine every 50-75hrs. It's simple procedure with 3 gal tempo fuel tank at stated in the link above. Throw a pint of outboard oil in that same mix and you've got the perfect winterizing juice. I have extreme doubt's if any of those carbon inhibitor additive's do any good at all. The worse part of them is people think by using them they don't need to do real decarboning.

Ed, you know I've never seen or heard of one of those the 12 spark plug Suzy's with a carbon problem. I've thought for a long time that extra spark helps for a cleaner burn in the combustion chambers.
