Explanation in Petronm website https://www.petron.com.my/web/site/slider/20 under Port Dickson Refinery tab paragraph #4 says

"Crude (predominantly light low sulfur crudes) is imported and processed to produce a wide range of petroleum products that includes Gasoline (U95), Jet fuel, Diesel, LPG, and Low-Sulphur Waxy Residue (LSWR)."

I have questions regarding to the blog dated 3rd Feb with the title "Difference between Petronm and Hengyuan". It says Petronm's refinery is a simple one which is suitable to process only sweet crude which is more expensive. However, WTI is currently far cheaper than the Brent Crude and yet WTI contains a lot less sulfur than Brent Crude. Also, it says that Petronm is currently unable to produce fuel oil that contain not more than 0.5% sulfer. But WTI contains only 0.24% sulfur and assuming that Petronm is using WTI, how can the fuel oil it produced contains more than 0.5% sulfur? Can someone here explain? Thank you.
