Is this engine oil ok to use?

I've owned a few bikes dating back to the '60's. Always try to ensure I used a better than good motor oil. I used Valvoline for a period of time, then I switched to Castrol GTX. When I was in Alaska and had my skunk I
put some Mobil 1 synthetic in it. I drove it cross country with it in it, only problem I had was the oil tended to dissapear, when I asked a Suzuki motorcycle mechanic about using it, he said "I wonder where it goes?" without any mention from me about it dissapearing so I switched back to conventional.
Now I've been using Amsoil synthetic, no problems. I'm a firm believer in
synthetic oil, far superior to conventional oils, there's no doubt about that. I'm coming up on an oil change, and after reading this post, I think I'll try some of that "genuine" synthetic (oxy moron) Shell Rotella 5w-40 diesel oil.

The following Oil analysis reports were taken from Bob is the Oil guy...

NOTE: The Vavoline motorcycle oil has less zinc and phosphorus (high pressure additives) than the Rotella T6 synthetic. Both are certified for use with wet clutches.

The synthetic base stock oil will not break down as fast as the dino base stock so the oil will last longer.

Thanks Ed,
Thats really good to know since I just picked up a gallon of the "Genuine Synthetic" Rotella T6 yesterday, I was wondering if I picked up the "right" one, no I have no doubts.

My local Walmart has the 2.5 gallon jug of Rotella 15w40 for $25.

That's what I get. it's excellent - nice sweet aroma with a slight nutty aftertaste.
