Congress blamed BJP-led central and AAP governments for the rise in petrol and diesel prices at a time when fuel rates have "plummeted internationally".
"With crude oil prices plummeting as low as USD 58 per barrel internationally, petrol and diesel could be sold for Rs 38 and 30 respectively in Delhi if excise duty and VAT are rolled back.
"The 'Modi + Kejriwal Tax' has pushed up the prices and people are bearing the brunt by paying a high price for petrol and diesel," a statement quoted Delhi Congress chief Ajay Maken as saying.
"Consumers had to pay just Rs 31 as taxes for Rs 100 worth petrol when Congress was in power, while crude oil was priced at USD 108 per barrel internationally," he said.
The latest increase had come on May 31, when oil companies hiked petrol price by Rs 2.58 per litre and diesel by Rs 2.26 a litre.
The party plans to present the signature campaign's outcome to Prime Minister Narendra Modi and Chief Minister Arvind Kejriwal seeking reversal of the hike.
