Setara RON 95, Amankah Bioetanol Diminum Mobil Modern? Uzone.id - Satu pertanyaan penting terkait rencana Pertamina untuk meluncurkan BBM jenis baru yang merupakan perpaduan antara Pertamax dengan etanol adalah, seaman apa BBM baru ini untuk mobil-mobil modern?
Untuk menjawab pertanyaan tersebut, kita perlu mengetahui seberapa banyak kandungan etanol pada BBM baru sekelas Pertamax tersebut.
Vice President Corporate Communication Pertamina Fadjar Djoko Santoso, dikutipUzone.id, mengatakan bahwa kandungan etanol pada BBM jenis baru tersebut adalah 5 persen.
Adanya campuran itu membuat Research Octane Number (RON) BBM campuran Pertamax dan Etanol lebih tinggi dari 92. Kemungkinan akan ada di kisaran oktan RON 95.
Mobil-mobil modern, berdasarkan panduan di manual book, rata-rata masih bisa mentolenransi campuran etanol pada BBM tidak lebih dari 10 persen.
Kita ambil contoh untuk mobil-mobil Toyota. Pabrikan Jepang tersebut masih memperbolehkan penggunaan bahan bakar campuran ethanol dengan kandungan hingga 10 persen.
Pastikan bahwa campuran bahan bakar dengan ethanol yang digunakan memiliki angka oktan sesuai dengan di atas. Seperti Avanza, yang mengharuskan menggunakan BBM tanpa timbal dengan minimun RON 90 atau lebih.
Sementara efek yang ditimbulkan kalau menggunakan BBM dengan kandungan etanol lebih dari 10 persen, mengutip manual book Hyundai, dapat menyebabkan masalah drivability dan kerusakan pada sistem bahan bakar, sistem kontrol mesin, dan sistem kontrol emisi.
Jadi kesimpulannya, selain lebih ramah lingkungan dan oktan lebih tinggi, untuk mobil-mobil modern, kandungan 5 persen etanol pada Bioetanol-nya Pertamina masih aman untuk dikonsumsi.
