Mobil1 10w-40 and 15w-50 is not "energy conserving" IIRC. Mobil1 10w-30 and below is.

 

I use amsoil fully synthetic, and a k and n filter, but have heard about scotts oil filter, its pricey but reusable and is basically insurance for your bike, you dont want to get cheap with oil, because lets face it oil is farely cheap

 

at 110/barrel, oil is not cheap.

as far as protection...there's more to it than just oil brand mang...

amsoil is by far the best and you can keep it longest in your motor without changing it out as long as you also have a great filter.

the other oils would protect just as well, but will shear down much faster than amsoil.

 

Well i just changed my oil saturday and decided to take the bike out for a ride in 40degree weather. Bike shifts so much better and is so much smoother with mobil 1racing 4t

 

Roger that, but I like something that I can walk into an autoparts store and get immediately.

 

Thats what i did hahaha. Autozone carrys it anyways and ive been to 3 of em. I searched online for something cheap and cheapest i found Racing 4T for was 12 a quart then i went to autozone and found it for 8.50

 

Regular M1, 10w-40 and above will work just fine. And if you don't trust me, look on the back of the bottles at the SAE label thing. I took a look when I was at Wal-Mart and saw that the 10w-40 and 15w-50 were NOT marked Energy Conserving while, the 5w-30 was....to be honest I forget what the 10w-30 was, but what ever it was it surpized me so that leads me to believe that it was not Energy Consverving....

 

+1 on the Shell. Awesome stuff for a great price! $16 a gallon for full synthetic... can't beat it! I actually like it better than Repsol full synthetic.

 

Well the regular car oil has molybidium which is a friction aditive enhancer. Since we have a wet clutch it might cause it to slip.
