It is worth mentioning that both Shell V Power Diesel and Petrol have detergents included in their additive packs, so if using premium fuels regularly, there should be no need to use any other additives (e.g. Redex/Forte/Millers), and no need for on-off cleaning (e.g. TeraClean).
Sebenarnya pada bulan April 2022 sendiri, Shell melakukan dua kali penyesuaian harga. Pertama di awal bulan, dimana Shell Super dijual dengan harga Rp.16.500 per liter dan Shell V-Power di angka Rp16.750 per liter. Namun per tanggal 22 April 2022 lalu, harga yang digunakan adalah Rp15.850 pada Shell Super, dan Rp16.750 per liter untuk Shell V
After looking into this a bit, I believe one can achive almost similar effect using ECOMAX with ordinary diesel, as using V-Power diesel. The cost of using ECOMAX (500 ml for 500 l) is about 2 pence/liter. If the price differens between ordinary diesel and V-Power diesel is more then 2 pence/liter, then it seams to be more economical using 1LDpqNI.
