Ford Marine Lima 2.3 Liter, Shell T4 15W-40 63 Hrs

[A310]

Metals look normal to me for a boat motor but diesel oils aren't what they used to be as far a ZDDP levels go. I would go with a "classic car" type 20-50 or a marine 25-40 oil, maybe even a straight grade.

Overall it's not too bad, did shear the oil down to a 30W, but not uncommon for a marine engine. See how it does after this season and get a synthetic 15W40 or 20W50 for next season.
