Don't know why are so many positive feedback here, honestly speaking this petrol sucks. My fc drop from 350km per full tank(rm70) to 280km just by using this petrol. Bare in mind, driving style remain consistent. And I pumped 3 tanks of premix, still same

I will wait until August and test again... Heard petronas shutdown to do maintenance..... So the petro maybe imported...
Using the imported sure can get +ve feedbacks while using the local sure can get mixed feedbacks....

my fuel consumption went up after using Ron95Xtra

previously using Shell 95 then Petronas 95 my mileage is around 11.xxkm/L to even 12.xxkm/L but now with the new Xtra, my mileage is 9.xxkm/L

i always keep a record of my fuel usage using an app on my iphone so it cant be wrong. Either my car suddenly minum more or Xtra drinks more.

Now Im switching back to Shell for a month to see whats my results

Me too , my savvy fuel after this more sucks, i always drive until redline,
prevously can last longer.
