Yep. As usual Reelapeelin is right on the money. I should have added that hint in my post. It's just a big empty plastic bottle with graduations printed on the outside. You find the one for your ratio (50:1 for me) and you fill the bottle to the line indicated for the number of gallons you're going to put into your tank. Mix the oil with a gallon of gas and pour it into your tank, then fill your tank with the number of gallons you measured your oil to.... presto... all done at the proper ratio.

Another hint... Through trial and error I've learned a spot on my gas gage where, when the needle is at that point I know that I have room in my tank for 35 gallons of gas. I put a small piece of electrical tape cut like an arrow head on my gas gage pointing to that location. When the needle gets to that pointer I know that I've got the room in my tank for 35 gallons. That way I'm always mixing oil for 35 gallons and my ratio is never rich or lean... Anything over that amount that I want to put into the tank I mix outside the main tank it a 5 gal gas tank, then I pour it into the main tank.
