Welcome!
I would suggest you just take a couple of hours and start reading posts.
The whole "wax in Quaker State" thing has been discussed at great length. Confusion over the chemical term "Paraffinic hydrocabon" is the main issue, IMO. Hint, methane gas (CH4) is a paraffin, and certainly is not wax.
The statement about ash is another misunderstanding. Ash content in oil specifications refers to the percentage of leftover ash after the oil is burned, not ash in the oil itself.
