What is Reddit's opinion of BigOil Engine Selector?

From 3.5 billion Reddit comments

Here is a free app that I use to figure out the correct engine. Plug in the information from the 2 clipboards (in the house and lab) and from the computer in the lab, and it will tell you the correct engine. It's worked every time for me, and makes big oil so much easier.

I always just used this app since it came out. Faster and doesn't rely on YOUR memory.

I couldn't find it in the Dutch store, however apparently there's an entire app just for the Engine in Big Oil:5+

There's an app (android not sure if apple) that helps you figure out the right engine.

Thank me later. I don't let anyone touch the engines. If you aren't host, you shouldn't be touching then anyway.
