Unhappy 2.5 Knocking?

Hello, I am new here, I have a 98 with a 2.5L I just bought it with 104k Miles on it and did and oil change two days ago. However, it recently started to knock under revving and acceleration, and sometimes cruising. I used 4 1/2 Qts of 5w-30 High mileage, and put a new oil filter. Should I check the timing belt?

I dont know if this would help, but my 2002 Hyundai sonata started knocking, they are known to have lifters stick and they recommend a higher octane of fuel to regulate the problem. One tank of 89 octane (instead of 87) problem solved.

Ill give that a try, I also heard that if I use a heavier weight oil such as 10w-30, it'd stop.

In all of my vehicles I always use 10w30 with a lucas blend. Had a 1992 honda accord with close to 250,000 miles with bend valves run almost like new with this mix.
