OCI and oil type unknown. 4 cyl 2.0L turbo 110K miles. Rough range guesses on how many miles this engine might be drivable? The high (29-35) mpg seems a bit surprising? Also possibly a HG problem. Thank you.

BLACKSTONE COMMENTS:
Wear metals were high enough to suspect the engine did suffer some damage from the low oil level. Bearing wear was the worst (see copper and lead), though aluminum and chrome don't look good either and we think this shows a ring problem, especially since you noted the low compression. Iron is from cylinders, rotating shafts, and other steel parts. Universal averages show normal wear from this type of engine after 5,500 miles use on the oil. Sodium and potassium may show anti-freeze. The TBN was okay at 2.3, so we don't think this oil was run long.
