Starting fluid was designed for starting Diesel motors and is good for nothing else.
It offers 0 lubrication and High detonation which will eventually damage any gas motor.
It was????????? using it on a Diesel is a big no no as well!!!!!!!!!
Using it on some diesels is a big no no that's true. Certain (maybe all) air cooled industrial engines come to mind. Deutz, Onan generators, things like that. But for the old Detroit 6-71, 6-92, 8-71 and old Cummins diesels it's perfectly fine. Diesels in late model trucks & stuff might well be a different story.
