I hope I'm not pestering anyone, I really am trying to wrap my head around this.
Diesel burns a lot differently than gas does. Diesel is supposed to ignite with just compression heat thats how a diesel engine works, the fuel is sprayed in and it ignites from heat of compression gasoline has to be able to withstand the compression stroke and to be able to wait to be ignited by the spark thus you do not want it to ignite from compression there-go higher octane for gas lower for diesel

at least thats what I've been told
