What is a Core Charge?
A core charge (also called "core deposit") is similar to the deposit you might pay for a can or bottle of soda and is a standard requirement in the auto parts industry. For example, in many states, to promote recycling, you pay a deposit when you purchase a can of soda and receive your deposit back when you return the empty can. Many automotive parts have a core charge, or core price, that works in essentially the same way as a soda can deposit.
30 Day Core Charge Hold
You authorize Tamerx Diesel Products, to hold your credit card for the specified core charge amount and that you agree to return your core with 30 days of receiving the purchased part. When we have received your core return, the hold is released and the core charge payment is canceled.
The customer, or parts buyer, is responsible for any shipping costs associated with core returns unless otherwise specified in the product listing/detail page. Tamerx Diesel Products offers prepaid UPS shipping labels (SKU numbers UPS-CR1 and UPS-CR2) for use in returning your core that are available for purchase on our website during your shopping/order process.
The shipping label you will need to use for the core return is dependent upon what part you are purchasing. UPS-CR1 is good for cores weighing up to 20 pounds. UPS-CR2 is appropriate for shipping cores weighing 21 pounds or more. You must include enough information with the core return that clearly identifies it as a.) a Core Return, and b.) contains enough information we can use to clearly associate the core return with your order. Including a copy of the invoice or packing slip that came with the original shipment, clearly marked "Core Return", is ideal. Alternately, you can include a note marked as "Core Return" that includes your order number, full name and address, and phone number or other contact information. Failure to include this information with your returned core will most likely delay any due core credit being issued and/or delay any applicable warranty activation. Core returns need to be for the exact part purchased and cannot be damaged. Substituting another part in place of the part you have purchased is not acceptable.
All fluids must be drained.
If you have purchased a set or a parts package, you will need to return cores for all components of the set. For example, if you have purchaed a high pressure oil pump with an IPR valve, you will need to return both HPOP and IPR valve cores to receive proper credit. If you have purchased an EGR cooler/EGR valve package, your core return must consist of an EGR cooler core and an EGR valve core, or core credit will not be given.
Core Charges are often mandated by state legislature, and, as such, the actual core charge and taxes on the charge may vary depending on the state in which you buy your part. The Tamerx Diesel Products core charge presented to you online today with your item is representative of the most common core charge.

The Diesel Particulate Filter (DPF) is designed to trap soot and reduce harmful emissions, but over time it can become clogged with soot and ash. While regeneration helps burn off soot, it cannot remove ash buildup. Choosing the best DPF cleaning method is essential for restoring exhaust flow, improving engine performance, and extending the life of the filter.
Most Effective Methods for Cleaning a DPF
-
Professional Off-Vehicle Cleaning (Best Option)
This method removes the DPF and uses thermal and pneumatic processes to safely eliminate soot and ash without damaging the filter. -
Thermal Baking and Air Pulse Cleaning
The DPF is heated to break down soot, then cleaned with high-pressure air to remove ash—restoring near-original flow rates. -
Ultrasonic Cleaning
Some services use ultrasonic waves in a controlled bath to loosen deposits, effective when combined with proper drying and inspection. -
On-Vehicle Forced Regeneration
Useful for light soot buildup, this process raises exhaust temperatures to burn soot but does not remove ash. -
Chemical Cleaning (Limited Use)
Spray-in or additive cleaners may help minor restrictions but are not effective for heavy soot or ash buildup.
Methods to Avoid
-
Pressure Washing or DIY Cleaning
Water or improper chemicals can damage the filter substrate and sensors. -
Repeated Forced Regens
Overuse can cause excessive heat and lead to DPF or turbo damage.
The best way to clean a DPF is professional off-vehicle cleaning using thermal and air-based methods. This approach safely removes soot and ash, restores airflow, and extends filter life. While forced regeneration and chemical cleaners may help in early stages, proper cleaning ensures long-term reliability and emissions compliance.
Frequent regeneration cycles, increased smoke, or loss of engine power can indicate the filter is becoming loaded with soot. These symptoms usually mean the filter needs inspection or cleaning.
Regeneration occurs automatically when exhaust temperature and engine load conditions allow the stored soot to burn off. Driving at higher speeds or longer distances typically allows the DPF to regenerate effectively.
A clean, functioning DPF supports efficient exhaust flow, which helps maintain normal fuel usage. When the filter becomes too restricted, increased backpressure can slightly decrease fuel economy.
Using high-quality diesel fuel, performing regular oil changes, and keeping the engine warm enough for regeneration all help protect the DPF. Routine inspection during service intervals also ensures it’s working well.
