Buying Guide
Choosing the right DPF cleaner additive depends on several factors. Here are some tips to help you make the best choice:
- Consider your vehicle type: Some additives are specifically designed for certain types of diesel engines. Always check the product label to ensure it’s compatible with your vehicle.
- Assess the severity of the problem: If your DPF is heavily clogged, you might need a stronger cleaner like Cataclean. For regular maintenance, a milder option like Liqui Moly is usually sufficient.
- Read reviews: See what other users are saying about the product. Pay attention to both positive and negative feedback to get a balanced view.
- Check the dosage: Some cleaners are more concentrated than others. Make sure you understand the recommended dosage to avoid over or under-treating your fuel.
- Think about your driving habits: If you mostly do short trips, your DPF is more likely to clog. Consider using a DPF cleaner more frequently. Highway driving helps to naturally clean the DPF through regeneration.
