4 stroke oil brand/kind?

[magnoman]

Hi, was wondering about what kind of 4 stroke oil to use in a F225.
In the manual it does not state syns. But I know from experience with my 4 stroke Jetski and my twin turbo car. Syns are much superior and Amsoil is one of the best rated. I use Amsoil syn marine in my jetski for years not one problem? The Marine grade has some additive to fight corrosion from the engine sucking in salt air..
The Amsoil is not cheap but either are these motors...

Re: 4 stroke oil brand/kind?

Oh Boy,, Ok I will make it more simple, Is it Ok to run synthetic oil in Yamaha F225?

Re: 4 stroke oil brand/kind?

If you run wide open most of the time and put a lot of hours on the engine in a short amount of time, it won't hurt anything. What you don't want to do is run synth in an engine where you put less than 50 hours per year on it and do a lot of low rpm operation.

Re: 4 stroke oil brand/kind?

You might want to read what Yamaha says about marine 4 stroke oil before you decide. Look here to read about it. You have to get the oil from a dealer though. http://www.yamaha-motor.com/outboard/yamalube.aspx

 

[walleyehed]

Re: 4 stroke oil brand/kind?

Interesting read there Bruce...I find it extremely interesting that Yamaha is claiming their oil is used as the standard for TC-W3 testing....this would open the door to say Penzoil makes that for them...last I saw, penz semi-syn was the std for comparison.
Don't let them fool you into thinking you must use their oil only....that's bogus and against the law unless they supply you with their oil at no charge....Interesting.
I do believe in the FC-W rating when recommending an oil, just make sure it's the correct weight for your engine.

Re: 4 stroke oil brand/kind?

Here's analysis of some marine and other oils that's interesting
http://www.bassboatcentral.com/oilreports1.htm
The YamaLube certainly appears to have more additives than others though at 4.99 per Quart it's tough to justify $30 in oil alone for an oil change. I've always run Mobil 1 except in my Yamaha. Maybe I'll switch too.

Re: 4 stroke oil brand/kind?

It is interesting to note that Yamaha uses a semi-synthetic oil for the 2 stroke engines but the 4 stroke oil is not synthetic; I think that tells you something important. I have all 2 stroke engines and always use Yamaha 2-M in them. I find that it is cheap insurance.

Why does the low amount of hours per year dictate not using synthetic?

It's time for an oil change and I wanna know why......

really why?

Re: 4 stroke oil brand/kind?

Consider what the reasons are for using synthetic oil.

Reduction of friction (heat reduction)

Increase of oil change interval due to better lubrication(see above)

Those are the opposite results of what you want in an raw water cooled outboard. Four-stroke outboards struggle to achieve and maintain operating temperature and a consequence of that struggle is fuel diluting the oil of the crankcase. So, if you use synthetic oil, you have increased fuel in the oil and that means you will have to change your oil more often than you would with a dino oil. In theory, the use of a synthetic oil is borderline cost effective because you could go twice as long between oil changes. However, in outboards it is not cost effective because you end up changing the oil twice as often.

Keep in mind that the above is, in general, the expierence of the average person. There are some conditions where the friction reduction properties of synthetic oil, in outboard use, can be used to justify its use. Such as a commercial application with unusually high, continous, RPM use. Other than that you are throwing your money down the rat hole by using synth.

Re: 4 stroke oil brand/kind?

Since the price of Yamalube is about the same as Mobil 1 then the heat reduction would be the main issue and the potential of making oil (fuel dilution) right? How about a conventional oil or the Penzoil Outboard oil.

Last question disregarding price if my motor has never seemed to experience any type of fuel dilution what is the harm in running synthetic or the possible benefits? Not trying to argue just wanting to convince myself that I'm making the right choice.

My typical running is point A to point B very little idleing usually running about 5000 rpm or more but I'm only putting about 40 hours or less a year.

Re: 4 stroke oil brand/kind?

Probably no harm in your case based on your habits...But, no benefit either. Without an extended oil change interval synthetic has no benefit. People ask me daily if the brand of oil is important...My answer is always the same. Buy the brand that YOU like, just make sure it's a dino 10w-30. In some brands and models a 10w-40. The only possible damage that can occur as a result of synth use is from the dilution effect. That can and does happen with dino oil too. Synthetic just increases the likelihood of that dilution occurring. We have found that roughly 80% of dino users get some degree of fuel dilution that is noticeable by casual observation. I have yet to see a synth user that doesn't have noticeable dilution. I'm not saying that all synth users have it. Just that all that I have never observed any who don't.

Most of the people who think that synth use has not caused dilution in their engine oil fail to consider that they burn off some of it at higher RPMs and believe that is going to make the dilution problem a non problem by running the thinned out oil. But, consider the following logic train:

You buy expensive synthetic to protect your engine from heat.

It increases dilution.

Which reduces the protection from the oil that you thought you would increase your engine's protection.

It's a trap. If you have to burn off the fuel in the oil your increasing the wear by doing so.

An outboard's raw water cooled nature makes some friction your friend, where as in a car it is almost certainly your enemy. Different rules apply here.
I run Mobile One in all our autos and wouldn't run anything else. But, not in a boat...Never.

PS

Never is along time and I reserve the right to change my advice based on future engineering changes and possible chemical blend changes to an individual oil With catalytic converters coming in the future they may provide enough additional heat under the cover to justify synthetic use.
But that a whole other future misery as brought to you by:

The EPA

Remember, the government is all wise, all knowing and is your friend

Re: 4 stroke oil brand/kind?

Thank You VERY much!

Okay last question...( maybe ) is there any problem in switching to dino oil after extended synth use?


and

how important in your opinion is running a "certified" marine dino oil

 

[rodbolt]

Re: 4 stroke oil brand/kind?

just use a brand that has the FC-W rating and is the correct viscosity for the ambient temps your running in.
most synthetic oils do not contain the correct anti-corrosion inhibitors or the additive package to adequatly protect the shiney metal parts under the gray paint during long periods of inactivity.
in fact at 40 hours a year I would also reccomend a can of crank case stor-N-start or an equivalent oil additive.
FC-W Four Cylce-water cooled.
dont confuse it with TC-W two cycle-water cooled.

 

[Pas Bon]

Re: 4 stroke oil brand/kind?

Thank YOU TOO!

Re: 4 stroke oil brand/kind?

When Mobile one was introduced it was said that switching back from synth to dino would result in leaks....It probably did. I never chanced it because I am a pessimist who just "knew" my car would leak like a fat man in a sauna. On a engine produced in say the last ten years....I doubt that you would see any kind of leak.

Like Rodbolt said,

"Just use a brand that has the FC-W rating and is the correct viscosity for the ambient temps your running in."

I personally don't place as much emphasis on the use of FC-W oil. But only because I recommend oil changes twice as often as called for by the engine manufacturers.

 

[rodbolt]

Re: 4 stroke oil brand/kind?

yep, kinda like a late model MPI 5.7 Volvo VS a late model 5.7 MPI mercruiser.
volvo says warrenty will be void if synthetic oil is NOT used and mercruiser says it will be void IF synthetics are used.
same GM 5.7 with the same basic ratios and RPM ranges in the same basic hull designs. two different call outs.
one of my commercial guys has just over 5000 hours on his F225 and only uses napa oil filters and walmart 10W-30.
I wish I could get him to change the lower unit oil as often as he does the engine oil but he wont, first gearcase lasted about 3500 hours.
but at 40 hours per year I would reccomend a crank case stor-N-start type additive as well as a constant use of a fuel stabilizer.
I cant say much as my F150 is closing in on 2 years and I think there is 87 hours on it.
last time the hood was off was about 1 year ago at the 20 hour check.
dont do as I do just do as I say

Re: 4 stroke oil brand/kind?

well I just changed the oil...went with the Pennzoil Marine FC-W 10w30 and a fram TG 7317 filter.

Before you shout about the fram it was a toughguard not an extra guard and has not sure about the cardboard end pieces. Looks like a pretty good filter and about $5-$6 so half as much as a yamaha. probably should gone with the Super Tech Probably won;t make a difference in the big picture. I have used fram all my life with out a problem

TG7317

Wally world had Merc oil and Merc filters and the filter that listed for my Yamaha 25 and 115 looked alot like a SuperTech7317. It's a longer filter than the original Yamaha filter and after agonizing research and pondering I ended up with a fram TG so that's what I went with.

Changed the oil in the foot too! SuperTech 80-90 marine oil
