That oil is not used in jet engines. It is intended for air-cooled aircraft piston engines.

There are other aircraft oils that work just as well but cost much less. Much testing has been done on aircraft oils. The concensus is that straight-weight dino oils work better and the engines last longer.

That Aeroshell oil has an additive that came around in about 1978. Lycoming came out with the H2AD engine that was notorious for scuffing/galling the camshaft. The additive was supposed to help that.

It is SEMI-synthetic, not FULLY-synthetic.

My question is, why put in your car? You'll be wasting your money and potentially voiding your warranty.

The lawn mower? Have at it. But still, why waste the money?
