A single can of AeroKroil lasts an awfully long time and it is the same strength from beginning to end, if you shake the can.

My buddy, earlier in his career, managed 2 different power plants, one an aero-derivative frame 7 turbine generator, the other a massive IC diesel the size of a big house. They used Kroil by the drum, especially to disassemble and clean turbine wheels. It would cut through the carbon build-up and free stuff up.

We all use it on our boats these days.

Now, the ED's Red type home brew, after the acetone, MEK, kerosene, whatever eventually evaporates, you are still left with the Dexron, which is about 5W20 oil with a lot of detergents and anti oxidants in it. Just fine as a leave behind lubricant.
