Serious Scientific Answers to Absurd Hypothetical questions

Absolutely, though it would make more sense to store tanks of nitrous oxide, which is can be warmed and midly pressurized to be a liquid on Titan. Lower pressure = lighter tank, and liquid = denser fuel, both of which improve overall performance. Even better, N2O has a much higher fraction of usable oxygen (by mass) than air, even at the same density.

You'll have some fun dealing with temperature swings, though -- Titan's surface temperature is low enough that impure methane falls as rain and stands in lakes and "seas" (albeit at higher than standard pressure). Combustion, however, would be at a similar temperature to what we're used to, so instead of a jet turbine's combustion section running at ~800 C in a -10 C environment (jet cruising altitude), you've got ~800 C combustion chamber in a -200 C environment.Serious Scientific Answers to Absurd Hypothetical questions
