If your septic is working well and you aren’t killing the bacteria in it with excessive soap, you don’t need pump-outs at all, but that still doesn’t explain how pouring grease down the sink could ever help. It won’t even if what you mention about the septic layers is true.
If you pour grease down the sink it’s just going to congeal in your trap under the sink and eventually cause you nothing but grief.
you WILL need pump-outs no matter how well maintained it is. the tanks are finite as far as solids containment is concerned. if you never pooped or wsshed dishes/clothes at home, then yeah you could make it last a very long time with just piss. have never heard of anyone going that route
