You're going to have to have someone visually inspect it. There are dozens of possibilities and we can't honestly give you a fair assessment. Have it looked at by a competent shop.

I put in mobil 1 10w 40 oil in a 2004 lincoln avaitor and its still knocking...what oil should I use now?

If it is knocking you have bigger issues!

There are several "knocking" noises an engine can make. Most of them are not good. A good tech with a trained ear will be able to help narrow down the possibilities.

Some possibilities are a spun bearing or a rod knock. If it is either of these it is terminal and no oil will help. An engine rebuild or engine swap will be the only fix.
