Methods for making marine fuel oil compositions and/or marine gas oil compositions are provided. The fuel oil compositions can include a distillate fraction having a sulfur content of 0.40 wt % or more and a resid fraction having a sulfur content of 0.35 wt % or less. The distillate fraction can also have a suitable content of aromatics and/or suitable combined content of aromatics and naphthenes. The distillate fraction, optionally blended with a low sulfur distillate fraction, can be used as a gas oil fuel or fuel blending component. Using a distillate fraction with an elevated sulfur content and aromatics content as a blend component for forming a fuel oil can result in a marine fuel oil with improved compatibility for blending with other conventional marine fuel oil fractions.
