I went to my LHS in need of some fuel for my new Tower Trainer 40. The manual said I need 15% nitro with 18% oil. I told him that and he grabed some fuel and I bought it for $18 (for a gallon) (its wildcat). Well i got home and was going to fuel up and I looked close at the title and it said HELImix. like its made for a chopper?... If it ok to use it?..

Thanks
