low-octane

Not very potent

Low-octane describes something lacking power, intensity, or excitement.

The term comes from fuel ratings—low-octane gasoline produces less engine power than high-octane.

Figuratively, a low-octane thriller fails to generate much suspense, and a low-octane performance feels flat or uninspired.
