Give it a Chance , run it about 300 miles and oil pressure and noise in engine will quiet down usually, I put it in my 86 foxbody mustang 100000 miles on it and after 300 miles gained 18 pounds of oil pressure no more noise, and drain it and get it out of motor, put new oil and you will be surprised, bet lot of other guys have good luck with it to. Have a great day.

I know you made this with good intentions. It’s not just you. 👍You should always use your Manufacture Specified oil.
