P.S. the 1000rr isn't on the list??

[NicoBusa]

I was always told by the mechanics @ work to use motorcycle oil as opposed to car oil because the last one was not designed to protect your clutch and transmission.
If you constantly use car oil your clutch and gears are gonna wear out much faster since this type of oil does not have the additives that motorcycle oil does.
That's why it is usually cheaper.
And cars have a separate transmission fluid, there is your difference.
If you only put 5k miles a year on your bike and ride normal you won't feel the difference but if you RIDE your bike (meaning ride a little harder than normal) and do 2 or 3 times that mileage a year your shit is gonna have to be replaced more often.
there might be other cases but since we are only expressing opinions here and not trying to sell any products you do whatever the heck you want

The one true difference between a car oil vs a motorcycle oil is the zinc content. The zinc clogs up catalitic converters in cars and that is why the % was made less in car oils. However if you bothered to do some research (instead of listening to some psudo expert who works on bikes) you may have come across the Sport Rider oil article that broke down the oils and their content. They also paid to get an independent study to test said oil. Guess what, the motorcycle oils were usualy worse than the car oils in just about every category. Mobil1 15-50 beat out the motorcycle oils. The clutch wear is bull, as none of my clutches slip on track or off. As for the gearbox, that is a harsh environment but the testing still shows that the car oil is better. Look at the label of motorcycle oil. It has to meet the API standards. Those standards also apply to cars and to car oils. If the standars are the same then the oil has to be good enough for bikes. Once again you cannot go wrong with motorcycle specific oil but you are paying more for less. I am tired of this oil war you guys do what you want and what you think is best

[NicoBusa]

yeah you're right the war has gone on for years and it still will go on for many more.
it's like anything else: you ask 10 people and you're gonna get 10 different answers.
at least you bother doing research and it is not surprising if it all was a conspiracy from oil companies to sell the motorcycle oil at a higher price, I don't know, i just go for whatever says motorcycle oil and i like keeping my shit as close to factory as possible therefore I use stock filters.
but that's just me. It's good that you are sharing this info with everybody and i'm sure you're not trying to screw anyone, or wouldn't say anything if you can't back it up don't get me wrong- i'm just typing what I hear.
If you've done your homework you must know what your talking about.

I will believe the engineer over the mechanic

I have done the research a while back and Scudman is right. SuperBike Mike has done research on oils there breakdown, wear, longevity, and most important of all Horsepower factor, and for that reason I will only run Mobil 1.
And guaranteed he has seen the insides of more motors than all the members of this board put together. Just my .02

Since I can do three oil changes for the same money with better products, in my head, it is a no brainer! Did I just insult myself?

[bigjoe87865]

felt like bumping this.... i did my first oil change with what scudman recommended.... rotella 5-40 synthetic... and a purolator filter...

first of all i saved about 20$... the rotella comes in a gallon container... so it was more conveniant.. instead of 4 small quarts like the mobil one 15-50 i have been using...

and the purolator filter is awesome... it doenst get jammed up in my filter socket what so ever... usually i have to wrestle with the honda filter being stuck to my socket.

its a tad bigger...and blue color is a nice change...
---

i used to change the mobile one every 5k... im not sure if i should extend the rotella that long..... the mobile one is the gold cap "extended performance" which states 15k in cars....

scudman.... any input on that?

There is also specific oil for motorcycle even in amsoil, mobil one which are the some of the best synthetic around...

Royal purple is the best. and that's what I'm using right now. the bike takes longer to overheat.
