Fuel & Fluids (i.e oil)

• Use ultra-low sulfur diesel , premium diesel fuel e.g. BP

• Use low-ash engine oil that is manufacturer-approved to prevent ash buildup and support DPF longevity.

• MAKE SURE ENGINE OIL is not higher than the the maximum mark on the dip stick. We always recommend 3 / 4 full as oil in diesel vehicles is very different to petrol vehicles. Produces more oil when regenerating. If over filled this can trigger DPF dashboard light.

• Use high-quality fuel additives to improve combustion and reduce soot.

Driving Habits

• Avoid frequent short trips—DPF needs time to reach regeneration temperature.

• Drive at highway speeds (60+ km/h) for 20–30 minutes weekly to promote passive regeneration.

• Avoid excessive idling, especially when parked or in traffic.

Regeneration Support

• Allow active regeneration cycles to complete fully—don’t turn off the engine mid-cycle.

• Learn to recognise regeneration signs (higher idle RPM, fan noise, slight fuel smell).

Monitoring & Inspection

• Regularly check for DPF warning lights or engine fault codes.

• Schedule inspections for turbo, EGR, and injectors to prevent soot overload.

Maintenance Tips

• Clean or replace air filters as per service intervals.

• Keep the EGR and intake system clean—a dirty EGR increases soot.

• Follow the manufacturer’s recommended DPF cleaning interval, even after a professional clean.

• A yearly DPF flush is a smart way to prolong DPF life and save fuel.

Prevent Future Problems

• Never use DPF delete or illegal tuning software—it’s both harmful and unlawful.

• Use only trusted additives—we recommend and use Bluechem products for top results.
