So, I recognize that this is an older post, but I think I may be able to offer some insight into the ever ongoing discussions around using Rotella T6 5w40 in high performance sport bikes.
I currently own a slightly modified 2000 ZX12R - Model "A1" production run..... and yes, Kawasaki rushed this first "A1" production run of 2000 on purpose to beat the European gentlemans agreement around top speed restrictions. My ZX12R is void of any factory top speed restrictions. With the added pipe, K&N intake, and "chip" it'll easily clear 200mph!
Anyway, I am also a process operator for Shell Lubricants! Yes, I blend and package the infamous Rotella T6 5w40. Now, I am legally not able to reveal the actual molecular components and quantities in the finished product but I can give some information as to why it is one of the best choices available on the market.
1st Shell's method of synthesizing base oil at the molecular level is the best in the industry. This process provides a base oil that flows easier and more consistently at extreme temperatures, but the best part is the way in which the oil molecules are also designed to hold together in longer "strands". This means that in high pressure, high temperatures, high performance / speed applications the body of the oil won't "shear" / break apart. This "shearing" in many oils is what causes many oils to retain air.... It sometimes looks like foam. Air in your oil can seriously reduce lubrication, increasing friction, which creates heat. This will literally "kill" your engine, and can easily occur with a regular / conventional multi grade oil. T6 also has a unique additive package that protects and supports the same type of high performance characteristics. It also contains just a touch of an additional "anit-foam" additive just to ensure "shearing" prevention. T6 is simply one of the best high performance (and multi-use) oils on the market..... I wouldn't use anything else!
The next thing to mention is that all motorcycle oils meet a specific standard, and they are "good" oils. But Yamaha, Kawasaki, Suzuki, or any other manufacture do not build any oil of their own. They simply just don't have the facilities to blend, package, warehouse, and test "their" oils.... They are ALL a rebrand of a compatible oil from another company! Shell Rotella products of any kind or grade are NEVER rebranded. They are Shell's flagship and proprietary products and are never anything else. Basically, you're not likely going to get the same superior quality oil from any bottle that doesn't have the oil manufacturers name on it. The oil manufacturers top tier products are their own bread and butter, they are their own marketing. They can't afford to risk losing that perception by someone finding out that they can get the same (or perhaps better) quality oil for a different price under a different name. Marketing suicide!
With proper maintenance and regular service using Rotella T6 5w40 you will never have a failure caused by your engine oil..... listen, I get paid either way, so buy it or don't buy it..... But I've used it, and I've used it HARD! I bring in, sample all of the individual base oils and additives, I blend the recipe, sample and package the finished product..... And I've seen the lab results for this oil, that's why "I" use it!
It's literally the "1" thing that I never worry about riding my Rocket...... And we all know that with all the crazies driving out there, 1 less thing to worry about when you twist it hard is a good thing!
Ride Safe 1st, Then Fast!
