I have a 2001 bonneville with only 62k miles on it and my oil psi gauge ussually at a little above 40 psi and then it gradually raised up to 120 over about 5 miles from home , changed the oil and the filter and still the same so what could be making my oil pressure peak like this?
oil psi at 120 on my 2001 pontiac bonneville?
