🚨 Diesel Hilux owners must maintain their DPF Diesel Particulate Filter to avoid costly repairs.

🔴 Symptoms of a Clogged DPF:
✔️ Loss of Power – Turbo boost is reduced.
✔️ Excessive Exhaust Smoke – DPF can’t trap soot properly.
✔️ Higher Fuel Consumption – Engine struggles to push exhaust gases out.
✔️ DPF Warning Light – Indicates filter is full.
✔️ Limp Mode Activation – Engine limits power to prevent damage.

📌 Fix:
✔️ Regeneration Drive – Drive at high RPM 80-100 km/h for 15-20 mins to burn off soot.
✔️ DPF Cleaner Additives – Helps clear deposits.
✔️ Manual Cleaning – Requires professional cleaning if completely blocked.
