Hello,

I bought used 745i last year, 81,000 miles and now it has 97500 miles. I noticed the oil consumption going up. Last summer 2 quarts after 12,000 miles and now this year 4 quarts after 5,000 miles. I had the two CCV replaced. No change in oil consumption but the car seems more peppy. I had a engine compression test perfromed today and all cylinders are 175 psi (number 4), 180 (5, 6), 185 (7,8) and 190 (1, 2, 3). The mechanic wants to replace the valve stem seals and head gaskets. Getting really expensive. How effective was the Lucas Oil Seal and 5w50 oil change in the car? I only drive the car from April through October and put it away for the Michigan winters. Otherwise, should I just keep adding the 4 quarts over the summer months? What is your thoughts?

The engine runs well and does not make any noises. Give me your thoughts.
