I was told a long time ago that 30wt motor oil could be mixed with gasoline for use in 2 cycle engines. Is this true? Was it true in the past when 2 cycle engines were "less sophisticated?"

Just wondering because I never seem to have the 2 cycle oil when I need it but always have lots of different motor oils handy.
