It’s called Pertalite, sold by Pertamina, Indonesia’s biggest oil and gas company, and I think it’s odd since it has octane rating of 90.

It means now in Indonesia you can choose 5 types of Gasoline: Premium (RON 88), Pertalite (90), Pertamax (92), Pertamax Plus (95), and Pertamax Racing (100). Pertalite cost about 0.62 USD per litre btw.

Now I wonder they choose octane rating of 90..
