Did a internet search and the best answer is Citgo bottles Yamalube and Quicksilver near Chicago. I don't completely trust that info, but I found it on a couple sights.

I run the Evinrude 2 stroke oil in mine as well, not cause of warranty or nothing motor only 29 years old... lol. I've used Walmart 2 stroke oil before and it smokes quite a bit more, actually alot more. I usually order Evinrude oil online from Walmart, I can get it for less than $20 a gallon in 3 packs with free shipping.
