evidence: Amidst this, a claim in the name of Indian oil is doing rounds on social media. The claim warns vehicle owners not to fill petrol to the maximum limit as this can cause an explosion in the fuel tank. The viral post reads, "INDIAN OIL WARNS The temperature is set to rise in the coming days, so do not fill petrol in your vehicle to the maximum limit. This can cause an explosion in the fuel tank. Please fill half the tank of fuel in your vehicle and keep room for air. This week 5 explosion accidents have been caused due to filling of maximum petrol. Please open the petrol tank once a day and let the gas build up inside come out. Note: Send this message to your family members and everyone else, so that people can avoid this accident. Thank you." [...] During the initial investigation, we did a keyword search on Google and found a tweet posted by official Twitter handle of Indian Oil dated 19 April 2023. While refuting the claim, it mentioned that refueling your vehicle up to the maximum limit is completely safe. The caption of the tweet reads, "Important announcement from #IndianOil. It is perfectly safe to fill fuel in vehicles up to the limit(max) as specified by the manufacturer irrespective of winter or summer." [...] It is evident from our investigation that no such warning has been issued by Indian oil. Filling the fuel in vehicles up to the maximum limit is completely safe. Hence, the viral claim is fake.
