Further to my posting....
I followed the break in rules exactly. My past experience showed it works except for this car. My 1990 Mitsu Mirage (Dodge label) never burned a drop of oil in the 6 years and 100,000 Kms. Next came a forgetable POS called a Plymouth Sundance. There was so much wrong with this car that oil consumption was the least of my concern.
Then came a 2000 Hyundai Accent. Just like the Mitsu. Good break in . Never used a drop of oil. Then there was a 2nd hand 2005 hyundai Accent with 12,000 Km on the clock. I don't know if there was any break in period from the previous owner but oil consumption was very slight.
I don't know where the oil is going. No drips under the car.... and no blue smoke..... no fuzzy slush in the radiator fluid.
