This study employed the Autoregressive Distributed lag (ARDL) technique to investigate the effect of petroleum products pricing on price level in Nigeria over the period 1990 – 2022. In order to achieve the purpose of the study, data on inflation rate, price of premium motor spirit, price of automotive gas oil, price of household kerosene, price of compressed natural gas and price of crude oil were sourced from secondary source. The results of our analysis revealed that: in the long run, prices of Premium motor spirit and compressed natural gas retarded inflation level marginally while prices of automotive gas oil, dual purpose kerosene and crude oil spurred general price level marginally.
