questions about laundry soap

I have bought:
Fels Nap soap (Winn Dixie)
Soap Powder (Kroger)
Borax (had on hand)
Got 5 gal bucket….

Now, I need the best recipe and any needed instructions.
Please… pretty please!
My husband has agreed to this and I don’t want to mess it up.

I did not buy the essen oil for smell.
I am wondering if I can pour some “PineSol” in the soap mix for
smell?

Does this get out grease from work?
Does this get out oil from cooking splatters?
Does this get out food stains?
Does this get out blood?
Does this get out grass?

Also, someone mentioned each batch makes 5 gals. But one
recipe mentions only adding 2 1/2 gal of water! Does it expand.
Any and all help is very, very appreciated.
I am hoping to make this today.
Thank you!!!
Kim
