The government has restricted industrial, commercial and institutional users from buying petrol and diesel from petrol pumps and instead asked them to source their requirements from bulk sale points, according to an official order. The restrictions, which will be in place for up to 90 days, follows abnormal demand growth, particularly that of diesel, in some pockets after bulk users started buying fuel from petrol pumps due to the pricing difference. While diesel at petrol pumps costs Rs 95.20 a litre in Delhi, bulk sales are priced at Rs 134.50.
