That's a lot of prop on that little Cessna! |

I wonder what it's like when you firewall it at 5,500 RPM! |

I just got a 2019 kia forte s to commute in, about 2k miles a month.
Should I just do the oil every 7500 miles like it calls for it do it more frequently? <snip>
If your car has a maintenance reminder system; just do the oil changes according to the system's recommendation.
Otherwise, for your drive parameters, go with the recommended mileage.
Sooner however, is better than later... |

There are a few problems with an LS Cessna.
The engine is heavier, so you can't carry as much weight.
You have to register the plane in Experimental Exhibition class. That means you can fly to airplane shows to show it off, and around your home field. You need a written waiver to fly anywhere else, each time. And you can't use the plane for commercial instruction etc. |

My Jeeps come with Iridium plugs OEM. The manufacturer says they are good for 100,000 miles. Do not believe them. Gap is to be .047". At 71,000 miles on the 2015 the gap is huge. The cabin air flows much better with regular filter changes too. |

The company selling the conversion were going to get all the paperwork and testing done to get a STC, the license to make a certified airplane replacement part or parts.
For an engine, that can easily burn a million dollars.
Not impossible, just hard.
Several companies make STC'ed replacement parts for airplanes. The Piper Cub can be completely rebuilt with legal exact copies of original parts. In many cases, improved parts, like a frame with reinforcements to prevent the crew being crushed in a crash when you land on the roof.
Since the patents are expired, and Piper no longer supports the old planes, STC replacement parts are cheaper, and in some cases, the only available, parts.
A few companies now make All the parts to make A Cub, so they sell them as kits, a big crate delivered to your driveway with everything except the engine. ( order that separately )
It's a bit like S&S, where you can get pan head HD clone engines. But more paperwork.
Those aircraft are registered, Experimental, Amateur Built, ( EAB) and can use improvements like slatted STOL wings and fancy, bigger engines. In some cases you can register a home built Cub clone in a Sport Pilot ( lower level driving licence ) class, but may not have enough limited Gross weight to haul 2 people. Lots of fudging going on.
There are a lot of ( not Cub clone ) EAB planes with car engines. Subaru boxer engines are popular, as they fit into the hole left by a Continental or Lycoming boxer, pretty good. It's a complicated subject, and often the biggest problems are not the car engine, it's the aftermarket parts used to "improve" performance, and the gear box to spin the prop slower than engine speed.
A typical Cessna sized airplane, and anything that can carry 2 or 4 people is roughly the same size, uses a prop large enough you only spin it at a bit under 3k or the tips break the sound barrier, converting power to noise. But not speed.
Yes, there have been supersonic props. NO, you don't want to be near them. The Republic XF-84H "Thunderscreech" made ground crews bowels let go if they were too close. Like 100 yards.

I don't know what oil they used, I can look it up. They changed it often. |
