Tindakan yang Direkomendasikan

Catatan: Prosedur disusun sesuai urutan kemungkinan. Selesaikan prosedur sesuai urutan.

Oli dalam Karter yang Berlebih

Periksa tingkat oli engine. Terlalu banyak oli dalam karter engine dapat menyebabkan engine mengkonsumsi oli.

Pastikan dipstick dikalibrasi dengan benar dan/atau dipstick benar untuk aplikasi terkait. Kalibrasikan dipstick dan/atau ganti dipstick. Rujuk ke Pengoperasian Sistem/Pengujian dan Penyetelan, "Sistem Pelumasan" untuk kalibrasi pengukur dipstick. Keluarkan kelebihan oli engine dari karter.

Kebocoran Oli di Luar Engine

Periksa kebocoran oli di luar engine. Rujuk ke Pengoperasian Sistem/Pengujian dan Penyetelan, "Sistem Pelumasan".

Kebocoran Oli di Area Pembakaran Silinder

Periksa kebocoran oli dalam area pembakaran silinder.

Periksa apakah ada blowby engine yang berlebih. Blowby engine yang berlebih akan menyebabkan konsumsi oli yang tidak perlu. Blowby engine yang berlebih dapat juga menyebabkan keausan engine yang tidak perlu.

Viskositas Oli

Konsumsi oli engine yang berlebih dapat juga terjadi jika oli engine dengan viskositas yang salah digunakan. Oli engine dengan viskositas yang encer dapat disebabkan karena kebocoran bahan bakar ke karter atau peningkatan temperatur engine. Rujuk ke Buku Petunjuk Pengoperasian dan Perawatan untuk informasi tambahan.

Kondisi Turbocharger

Periksa apakah ada kebocoran pada turbocharger.
