That it an Amsoil "brochure" on an Amsoil site. I don't trust anything Amsoil puts out about their products. They have a long standing reputation of misleading information and "studies" that use meaningless or skewed metrics. I'm not saying it's a bad product, but I would not believe it is the best either, especially based on their own tests.
EDIT: And make sure the product is actually API certified, if that concerns you, and not just labeled as "meets API specs".
I agree. Amsoil claimed their 2 stroke oil was certified TCW-3 compatible with other 2 stroke oil. I checked with the certification agency, bald faced lie. Agency went after them and they removed that claim but three years later they put a modified version back up and it still isn't certified by the agency. You can check the website, still not listed.
This from Amsoil porduct bulletin. No longer says it is certified, but it still strongly indicated it is with the wording used.
Synthetic 2-Stroke Injector Oil

API TC or TC-W3 two-stroke oil,
including those made by BRP*/
Evinrude*/Johnson*/Ski-Doo,* Polaris,* Mercury,* Arctic Cat,*
Yamaha,* Suzuki,* Kawasaki,* Mariner* and Force.*
Use as injection oil or 50:1 pre-mix (2.6 oz. per U.S. gallon
For Evinrude factory-lean setting, use AMSOIL HP
Marine® Synthetic 2-Stroke Oil.
AMSOIL Synthetic 2-Stroke Injector Oil is compatible with most
conventional and synthetic two-stroke oils; however, for best
performance, mixing oils should be minimized.
You guys are free to do as you like but I don't deal with companies that lie or mislead their customers through artful wording. I do not know which claims to trust thus I don't trust any of Amsoil's claims and I won't use their oil because of it. All of their first place results are from Amsoil paid studies, reminds me of the Tobacco companies funding "independant" cancer studies.
