Esso led the downward adjustments on Thursday afternoon, with a 6-cent reduction to its posted price for diesel — to $4.42, but held petrol prices steady.
At 6pm the same day, Shell, the London-headquartered oil and gas company, announced that it had dropped prices across its petrol offerings by 3 cents — effectively reversing its 3-cent hike on May 18.

Brent crude oil futures eased to US$110.83 on Wednesday after US President Donald Trump again asserted the war with Iran will end "very quickly", even as investors remain wary about the outcome of peace talks amid continued disruptions to Middle East supply.
Speaking to reporters on Wednesday, Trump said the US was ready to proceed with further attacks on Tehran if Iran did not agree to a peace deal, but suggested Washington could wait a few days to "get the right answers".
Asked how long he would wait, Trump said, "It could be a few days, but it could go very quickly."
Brent oil prices hovered around the US$108 mark at 9pm on Thursday, amidst reports that tankers, including those from China, have exited the Strait of Hormuz with six million barrels of crude oil.
