Oil and Filter change 6.5 qts.??
When I did the first oil + filter change I put in 6.5qts. This indicated over the full mark on the dipstick. I am guessing about 1/2 Qt. Is this a known problem, or unique to my car only? I am wondering if the book is right or if my dipstick calibration is wrong. The AC oil filter PF44 , referenced in the owners manual, is not available it's substitute is PF46 ....could this be the problem, the PF46 is a small filter.
