I would not accept this statement at face value. (It may prove to be true, but more likely it would prove not to be true.) First of all, Diesel engines use compression ignition and diesel oils are rated with specs starting with "C", like "CH-4" for a 4 stroke compression ignition engine; standard "H" is the 7th iteration.
Gas engines use spark ignition and oils rated (like) "SG". Any diesel oil you intend to use in a gas engine should carry a "Sx" rating as well as the "Cx" rating.
Rotella happens to have been tested to the JASO-MA spec, which is a motorcycle spec specifically designed to address wet clutch and transmission compatibility. Other Diesel oils may or may not meet the spec, but if it hasn't been tested there is no way of knowing. If it has been tested it will carry the JASO-MA rating as well as a SG or better spark ignition rating.
Rotella T6 meets the following specs:
API CJ-4, CI-4 PLUS, CI-4, CH-4, SM, SL, SH; ACEA E9; Caterpillar
ECF-3, ECF-2; Cummins CES 20081; DDC 93K218; Ford WSS
M2C171-E; JASO DH-2, MA; Mack EO-O Premium Plus; MB Approval
228.31; Volvo VDS-4
