Indian Oil has announced that oil marketing companies (OMCs) have made no change in the basic selling price of petrol and diesel."Considering the current crisis brought on by the COVID-19 pandemic, the OMCs have kept the prices of petrol and diesel unchanged with effect from April 1, 2020, which were otherwise also being maintained steady," said IOC spokesperson in a press release.The release also said that as per their commitment to the nation, PSU OMCs - Indian Oil, BPCL, and HPCL -- have fully transitioned to BS-VI compliant petrol and diesel across the country with effect from April 1, 2020, even in the face of the constraints posed by the COVID-19 pandemic.However, the increase in the retail selling prices (RSPs) of petrol and diesel in some states like Maharashtra, Karnataka, West Bengal, etc., with effect from April 1 "is purely on account of the increase in VAT rates by the respective State Governments on both the products from that date."
