You may also want to consider using one of the "high-mileage" oils for cars with more than 75,000 miles. A lot of brands offer these oils now. The so-called conditioners are supposed to soften and swell hard seals.

I changed to the Valvoline MaxLife in the 300E. Oil consumption declined from 1 qt every 800 miles to 1 qt every 2,200 miles. I was impressed. It isn't a cure for bad valve stem seals but it can slow the consumption down. The 300E has 210k miles and has never had the head off. I do believe the guides and valve stem seals were updated in the 90-91 cars though.

Keep us posted,
