klotz oil in my formula stx

im new here obviously, ill get pics in a few. once you see the pics you might recognize it from a different forum. question is I bought the sled off my dad and he runs klotz injector oil in it. I know that its real good oil to run in it but its real expensive to run it. am I able to switch to a regular oil or no. I don't want to open up a what's better to run oil thread. the sled is a 1994 formula stx 583
