Core Return Policy  

If you have purchased an exchange product, your order requires the return of a core. Cores must be returned within 35 days from the date of delivery to avoid late fees or core charges billed to your account. We are unable to provide a return shipping label for your cores, but we strongly suggest including this form in the box with your cores to ensure the core credit is awarded to the correct account. We also suggest documenting the tracking number for your core return shipment, and monitoring its transit until the tracking number shows delivery. If you are charged for cores or late charges and attempt to dispute the charges, you will be expected to provide a valid tracking number showing delivery of a valid weight to redeem credit.  

Packaging Instructions 

We suggest removing all drain plugs and completely draining oil from your core unit prior to packaging and shipment.  

  • Properly secure the cores into a box with at least three inches of clearance on all sides. 
  • Use an appropriate container, cushioning materials and at least three strips of packing tape. 
  • If reusing packaging, remove or black out old shipping labels including their barcode(s).

 Diesel Care and Performance Inc. is committed to providing exceptional customer service and delivering quality parts and services to all customers. How your refund is processed is determined by how you purchased your products originally. If you have purchased a Diesel Care and Performance brand item on a third-party website such as eBay or Amazon, please request a refund through these sites. Diesel Care and Performance as a third-party seller of these websites, is obligated to abide by the rules and regulations of the websites and their processes, in order to remain in good standing with these sites. Because you have previously paid for products or services through these sites, Diesel Care and Performance does not have access to process your refund or return outside these systems. Also, please be aware that if you have paid tax or additional processing fees through these sites, any approved credit or refund amount owed to you will be less these amounts. This is because tax and other fees are funds collected by the third-party sites, which Diesel Care and Performance is not compensated for.  If you would like credit on these amounts, you will have to address this request with eBay or Amazon directly. All products and services purchased through these sites are covered under the sites’ refunds and return policies. If you need more information on these policies, here are some helpful links.

If you are seeking full credit, less the shipping cost, back to your original payment method, we expect the purchased product to be returned in the following conditions: 

  • Product must be uninstalled and in its original packaging. Already opened the package? No problem! Just be sure the product is not damaged in any way and again, has not be installed in an engine. 
  • Product must be in transit to our facilities with a valid tracking number within 30 days of original sale to be eligible for a full refund. Customers are responsible for shipping the product back to our facilities located at 3901 Thomas Street, Memphis Tennessee, 38127.

Examples include; wishing to return 1 or 2 injectors from a full set that was purchased, wishing to return glow plugs from a ‘super kit’ that was purchased, etc. These returns can only be honored if all individual items are returned and uninstalled. 

If you previously purchased a rebuild service or a ‘made to order’ product, Diesel Care and Performance will be unable to provide a refund on this service. We will also not offer a refund on test and check services or other previously arranged services that are unable to be physically returned to our facilities.  

If you are wishing to return an item that is sold from a third-party vendor or manufacturer of ours, such as an engine overhaul kit, branded items such as MAHLE, Air Dog, ARP, etc., we will not issue credit until credit is issued to us by the vendor. Please note that these items also carry the manufacturer’s warranty, and are not covered by Diesel Care and Performance’s independent warranty policy.

Products that are not eligible for a refund include but are not limited to; o-rings, seals, opened piece part kits such as gasket kits, bearings, etc., major electrical components such as starters, solenoids, alternators, wiring harnesses, minor electrical components such as connectors, terminals, switches, shop supplies such as additive, paint, chemicals, etc. Again, any parts that are previously installed or damaged are not eligible for a full credit refund.
