Hobbsy,
To answer your question in all fairness no. I assumed that the sealed can was full, so I just added the 3 oz of castor per Bill Robison's suggestion. When I transferred the fuel from the metal can to the empty Wildcat plastic jug I use for transport the jug was noticeably low. By that I mean the fresh unopened gallon of 15% Wildcat Super Premium for my two strokes was about 1 1/2" higher. Now that is after I added the 3 oz of oil mind you. I would not imply that anything is being done by Powermaster that is not on the up and up. It is fine fuel and I will continue to use it for my Saito and YS engines. Just posting my observations when I saw this thread. It could be something as simple as the automatic filler is coming up short. My LHS carries Coolpower, Omega, Wildcat and Powermaster. so we are fortunate to have that many choices. The other brands come in visible containers, so there is no guesswork what you see is what you get and buy. I still have 5 sealed cans, so we'll see what the next one looks like as they are all from the same batch number.
