Wow, not the answer I was expecting! I thought I mentioned to here that I got Tower fuel, without really knowing the oil content, and people said that I should add castor oil to it, with some reference like you shouldn't feed your baby food when you don't know what's in it, or feeding your dog the worst kind of dog food 'cause it's cheap. The manual does say to use castor oil or castor blend if possible, but that it will run fine if you don't.

I guess I should have gotten a receipt for that bottle I just bought!

Oh well, thanks guys, this makes it a lot easier.
