Ok, maybe your car is IRISH and getting ready to celebrate St. Patty's Day?
All kiddin' aside, you may want to take a sample of that
oil and have it analyzed. The analysis can tell you what pct trace of water and gas are in the
oil as well as other metals and minerals. You will need to have a baseline test of new
oil performed to see what the new fresh oil has in terms of these elements, metals and minerals.
I would also stop idling your car for short periods in the winter months as you will not gas out your condensation if the oil temperature does not come up.
If you could, put some of the green old oil in a clead jar so we can see the color and opacity. That picture of the oil in the black drain tub just makes it look bad due to the black tub I think.
Fingers crossed for you Amigo.
