wow, 80 psi at idle, are you running a rod as a relief valve spring? Thats mucho psi at idle! I put wifes minivan 5W-30 oil in my beater Mazda and the oil light is now flickering at idle. Ill go back to straight 30, it never gets under 50 here anyway. Purolater filters (pep boys house is purolater, and most others are WIX) are about the same price as Fram, no need to get the orange ones.....
