No oil added up to 1st 1200 mile service. When I checked after the service the
oil level showed 1/2 way between the lines.
At 3100 miles total, got alert to add 1 qt & did so. Oil level now shows right at top line (took about 30 min to register). My assumption is that at the 1st service they were about 1/2 qt low on the oil change fill.
Consensus: used about 1/2 qt in 1900 miles......
