These chilli oils are generally designed to be tasty but not necessarily very hot. I used to eat lao gan ma out of the jar and this stuff is probably not as spicy (this brand appears to be marketed at westeners).
I did get one made locally brand at some Asian shop a couple years ago that was definitely on the much hotter side. Wish I remembered the name. Took me over a year to finish it. Strong onion presence which I love
