Policies

Core Policy

All orders which required the return of a core also require that Diesel Care and Performance has a signed core agreement and a valid credit / debit card on file prior to fulfillment and shipment of the order. If you do not wish to have a credit card on file for your convenience, you may pay for the core value at the time of order fulfillment, or Diesel Care and Performance may hold your order until the cores are received into our facilities. Once cores are received, inspected, and processed, we will fulfill and ship your order.  

The on-file payment method will not be charged unless the core is not returned within 35 days of product delivery. Once the core return is deemed late, the customer agrees to a 1% late fee per day, totaling no more than 30% of the monetary value of the cores, also known as consecutive late fees, until the core is either returned to Diesel Care and Performance, or the full monetary value of the core is billed to the customer.  

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).
