Just because you use it don't mean it's right, the manual says NOT to use it for a reason, so does Mobile 1. I dunno............

You can find 0W-30 synthetics with an SM rating which is better than the recommended SJ rating without friction modifiers for about a third of what Yamalube goes for. I wouldn't run a synthetic for at least a thousand miles (about where it feels like the motor is broken in). If you have to endure the type of temperatures we are enduring now (-40C the other morning) this stuff is much easier on the motor and is the difference between it starting or not. I just ran this stuff for four days of between -22C to -32C and it was great.

Tom got an apex??? awesome!!
congrats, Tom!!! coming from an oil guy, i would break in your motor with your yammylube before switching to a full synthetic!!! i you go straight to a full syn. then your motor will never be able to properly seat itself! personally i would go with the proven leader in synthetics.... the first co. to make and introduce synthetic oil! they have a broader viscosity rating and make an oil specifically for your four stroke motor!... amsoil 4 stroke 0W-40. proven better in all 6 API. tests!
just my 2 cents worth!! hope to see ya' on another TY ride!!

Here is a previous post of mine on S.A.E. ratings..
The Breakdown on oil
--------------------------------------------------------------------------------
for all those who have ever wondered about what type/wieght of oil to use, hopefully this helps!
-------------------------------------------------------------------------------
the society of automotive engineers(SAE) have established 12 different viscosity grades. vicosity grades will determine the oils dynamic viscosity and kinematic viscosity.
the dynamic viscosity is the first # you see usually followed by a W , which , yes , you can associate that # with winter to help you think of how it performs in cold weather.the SAE has determined 6 grades of "winter" formulas beginning with 0W and working up to 25W in 5 point incriments. what they are measureing with this is the lubricants ability to pump 60,000centipointe units with no yield stress at certain temps. for ex.
0W = 60,000 cP @-40*C
5W = 60,000 cP @-35*C
10W = 60,000 cP @ -30*C and so on till 25Wwhich is 60,000 cP@-15
basically the smaller the # the better protection for colder temps.
the next # measures the lubricants ability to pour or its kinemetric viscosity, which is measured by the time it takes an oil to pour out of a container. the temp. is always consistant at 100*C (212*F)
this is #ered from 20 -60 in 10 pt incriments and is measured using sabolt universal second(sus) for ex.
sae20@100*c will empty in min.5.6sus and a max. of9.3sus
30 = 9.3sus - 12.5sus
40 = 12.5sus- 16.3sus
60 = 21.9sus - 26.1sus
in other words the oil will empty out of the container just by pouring in 5.6 seconds (roughly) to 9.3 seconds
remember you do not want your oil viscosity to thin in hot temps. because you will lose you ability to lubricate and protect your engine.
a good ex is this. a truck driver leaves florida with a load of oranges heading for minnesota, in fla. he runs SAE 30 oil because of the ambient temp. in fla. when he (or she) get to min. the driver finds the SAE 30 is to viscious or thick to handle the sub zero temps and is having a hard time starting the vehicle. after changing oil to an SAE 15W the starting problem is solved and he can continue on. when he gets back to fla. he finds the SAE 15W is to thin due to the high temps. in fla. therefore the lubricant can not protect the engine like it should.
thus, they have made multi viscosity oils. the point is not that a certain oil is thicker or thinner because under different circumstances they will all flow the same it just depends on the temp. of the product.
how many times have we been in the north woods and the temp. has been -30* one day and 30* the next? i've seen it! make sure you choose an oil that is best for your climate and has a broad viscosity range to cover those sudden changes in weather!
basically the ultimate protection for any motor would be a 0W-60 but the viscosity range of that oil is nearly impossible to achieve
i run amsoil 0W-40 four stroke in mine and i love it!
next post on different comparitive tests run by the american petroleum institute(API) and exactly how and why an oil breaks down !
