AS long as you get the % of nitro and % of oil you need, and the ingredients are good quality, it doesnt matter what its packaged for, car or airplane. I am currently using Trinity Monster Horsepower 25% and adding Morgan fuel "cool power" a full-synthetic oil additive to bring the 12% oil in Trinity up to the OS recommended 18% oil for break in. Works well so far, and should for 30BUCKS A GALLON! The oil additive is 7.00 a quart, but a quart will mix many gallons to 18%, at least 5 Gallons worth.:stupid:
