DD;
Congratulatons! If there is settling of gunk on the bottom, something is wrong...He may be using lard, or hydrogenated oil...You should be able to find out just by asking anyone in the restaurant..
Are you getting it from the dumpster, or directly from his fryers?

We have a mexican place here that even has NFL (no F'n lard) on their T-shirts...(-:
If it's hydrogenated, don't use it...you will never get it out....and will surely clog your fuel system.....think of white waxy fat when cold turns solid....
You don't want that in your car.
