Oil Preference

[hayabusa_83]

obviously, according the manual suzuki recommends 10W-40 oil.
me being the non-observant guy i am threw in some 10W-30 on accident. at first i freaked but eventually realized it didnt make a difference. so question: ITS ABOUT THAT TIME AGAIN, AND I WANNA TRY SOMETHING NEW. WHAT'D YA RECOMMEND? WEIGHT? TYPE? HOW IS IT? ETC! (i'm using Valvoline SuperSyn now)
thanks,
Brian~

The oil that replaced it , the Extended Performance 15w-50 is made of the exact same base oils but with more zinc as a primary anti-wear additive, secondary anti-oxident .

Simply put , the EP 15w-50 is a better version of the old red cap oil with around 300 ppm more zinc and phosforus .

New oil analysis of the Mobil EP 15w-50


Moly 78
Boron 290
Calcium 2951
Magnesium 18
Phosforus 1230
Zinc 1381
VI @ 100c  18.0

Old Red cap 15w-50

Moly 210
Boron 130
Calcium 2540
Magnesium 11
Phosforus 840
Zinc 930
VI @ 100c  17.8

Motorex 5w-40

Boron 610
Calcium 2680
Magnesium 20
Phosforus 998
Zinc 1110
VI @ 100c  14.6

It's apparent to me that the EP 15w-50 is using a different type MoDTC " moly " . Probably the same type used in the Mobil race oil . They need less of it to use as an anti-oxident because the EP oil uses more zinc in which once again is an anti-wear additive primarily and a good anti-oxident secondary .

Boron and Overbased Calcium also serves as secondary anti-wear additives .

It's good oil for the money and better than "some" of the ultra expensive bike oils IMO .

More current oils .

If your talking about the gold cap 15w-50 Extended performance that just came to market it's a better oil than the old red cap was .

 

[Cuffee]

I use Mobile 4 MX4T! From the comparison above...It seems to be pretty good!

Cool.

 

[hayabusa_83]

anyone use amsoil....heard its up there with the best....?!

 

[cbibb]

Is this "red cap" or "gold cap" oil made for motorcycles? I was always told to use a motorcycle specific oil because of the clutch. Is this the red cap and gold cap oil found at wal-mart?

 

[thesnake]

perhaps a stupid question, but just how does one decide which is a "better oil" based on the composite breakdown? Do bikes have specific composit needs vs. cars?

 

[Krieg]

Castrol GPS semi-synthetic and an OEM filter. Stock weight. It will make your Busa shift smoother than silk

 

[thesnake]

cb-

no the gold and red caps are not bike oils, but are widely used.

I used it....But switched to Mobil MX4T. To be honest I can't tell the difference other than the bike seems to get hot quicker when sitting in traffic. I think that I will be swithing back to AMS oil.

 

[hayabusa_83]

isnt bike oil more expensive?
