1. A distillate fuel blend useful as a fuel or as a blending component of a fuel suitable for use in an internal combustion engine, said distillate fuel blend comprising:
- (a) at least one highly paraffinic distillate fuel component having a paraffin content of not less than 70 percent by weight and (b) at least one petroleum-derived distillate fuel component having an aromatic content of not less than 30 percent by weight, wherein the distillate fuel blend has an ASTM D6468 reflectance value of at least 65 percent when measured at 150°
C. after 90 minutes.

13. A process for preparing a stable distillate fuel blend comprising at least two components having antagonistic properties with respect to one another, said distillate fuel blend being useful as a fuel or as a blending component of a fuel suitable for use in an internal combustion engine which comprises the steps of:
-
(a) blending at least one highly paraffinic distillate fuel component having a paraffin content of not less than 70 percent by weight with at least one highly aromatic petroleum derived distillate fuel component;
(b) determining the thermal stability of the blend of step (a) using a suitable standard analytical method;
(c) modifying the blending of step (a) to achieve a pre-selected stability value as determined by the analytical method of step (b); and
(d) recovering a distillate fuel blend that is characterized by having a reflectance value of at least 65 percent as determined by ASTM D6468 when measured at 150°
C. after 90 minutes. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A process for preparing a stable distillate fuel blend comprising at least two components having antagonistic properties with respect to one another, said distillate fuel blend being useful as a fuel or as a blending component of a fuel such that the blend has acceptable deposit characteristics, said process comprising the steps of:
-
(a) blending at least one highly paraffinic distillate fuel component having a paraffin content of not less than 70 percent by weight with at least one petroleum derived distillate fuel component having an aromatic content of not less than 30 percent by weight;
(b) determining the reflectance value of the blend of step (a) using ASTM D6468 when measured at 150°
C. after 90 minutes;
(c) modifying the blending of step (a) to achieve a reflectance value of at least 65 percent; and
(d) recovering a distillate fuel blend that is characterized by having a reflectance value of at least 65 percent as determined by ASTM D6468 when measured at 150°
