Extra Premium = Normal Petrol + Ethanol + other additives
when ethanol burns it acts as a detergent cleaning interior engine parts. in other countries Acetone is also used to archive this.
I use Extra Premium because I notice the Following
1. My auto gear Toyota Vios up shifts Gears around the 2000 RPM level and more quickly to upper Gears (for normal petrol it is higher around 3000 rpm)
2. Increase in acceleration when accelerator is pressed suddenly (Ex:- When Overtaking)
3. Increase in Fuel Economy (might be due to shifting to higher gears more quickly and other Additives)
Note:- Ioc Extra Premium 95 will be the same standered 95 with additional additives.
Must try the New 95 Extra Premium one
