my honda accord died on me so now im driving a 2001 Chrysler Sebring LXi with the 2.7 V6. its known trouble area is easily clogged oil passage ways. i am getting a "Low Oil Pressure" warning at low RPM. any way to clean the oil passage ways and keep them from clogging? im thinking of running seafoam through the oil then doing full oil change with Full Synthetic and a really good filter. also, what weight oil should i use to prevent my passage ways from clogging up in the future?
