This is a "sludge motor" that previous owner had the oil changed and suggested an oil change was not needed? However the filter was not and appeared to be 100K+!
Thinking I may go with Shell Formula 5W-30 conventional oil as a flush? THen returning to Synthetic shortly!
In addition thinking about Liqui Moly motor saver from FCP Euro to take care of seepage at front and rear main seals.
Fram full synthetic 5W-40 is doing quite well and leaks appear to be improving?
WAG, leaking one quart /2500 mi.
Of course, I know replacing the seals would be the correct repair but maybe???
