Hi guys, just to share something I am doing just as a hobby - hope this helps you to estimate next week's fuel price - less of a surprise if it goes up and fuel up before the rush, or wait to fuel up until Thursday if it goes down

Malaysian Estimated RON95 & Diesel Fuel Price Calculation Spreadsheet

Estimated RON95 fuel price for Week ending 21 June 2017 - it's gonna go down by 4 cents to RM1.94/Liter ±RM0.05... (as of 20 June 2017)
Need more data on Diesel prices...

Early indications is that the fuel price will be going down again next week. Wait until Thursday to Fuel up. Our currency is growing stronger to the dollar, and MOGAS95 price has dropped since last week. Hopefully things will get better and better...
