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.
Built as a core component of the exhaust aftertreatment system, the Diesel Oxidation Catalyst (DOC) for Paccar PX8 engines is designed for model years 2011 through 2013. This unit helps treat exhaust gases by initiating oxidation reactions that reduce regulated compounds before they move further downstream. Its emissions-rated construction supports proper fitment, steady exhaust flow, and durability under prolonged high-temperature conditions. When symptoms such as increased soot accumulation, restricted exhaust flow, or aftertreatment-related warning indicators appear, replacing the DOC can help restore correct system operation. Manufactured with dependable materials and precise engineering, it supports consistent exhaust treatment across all compatible PX8 applications in this model range.

One of the most common long-term engine conditions that can gradually degrade Diesel Oxidation Catalyst (DOC) activity is chronic oil consumption. When an engine consistently burns small amounts of oil over time, oil ash and residue enter the exhaust stream and coat the catalyst surface.
Unlike soot, oil ash cannot be burned off during normal operation. As it accumulates, it slowly blocks the active catalyst sites inside the DOC, reducing its ability to oxidize exhaust gases effectively.
Other long-term engine conditions that contribute to DOC degradation include:
- Worn injectors, which cause incomplete combustion
- Rich fuel conditions that increase soot production
- Coolant leaks introducing contaminants into the exhaust
- Poor air intake sealing, leading to improper combustion
- Extended idling patterns, which prevent stable exhaust temperatures
Over time, these conditions reduce DOC efficiency without triggering immediate failure. Early signs may include more frequent regeneration cycles, rising exhaust temperatures, or increased strain on the DPF.
Because DOC degradation often happens gradually, regular diagnostics and addressing engine issues early are critical. Maintaining proper oil control, clean combustion, and stable exhaust conditions helps preserve DOC activity and extend the life of the entire emissions system.
It serves as the first treatment stage by oxidizing exhaust gases before particulate filtration.
Proper oxidation helps maintain smooth, predictable exhaust flow into downstream components.
Irregular temperature readings across the catalyst can signal uneven oxidation.
Faster activation allows emissions treatment to begin earlier in the drive cycle.
