Diesel Fuel Additive, 16 Oz.

We don't want to see you stuck with a part that is not right for your application, or that you no longer need.  We issue refunds every day to make sure our customers have a positive purchase experience.  All these are issued as refunds, we do not maintain store credits. Returns must be initiated within 30 days of receiving the order.

However, for various policy, safety, and regulatory reasons, a small number of items are non-returnable for credit.  These are normally noted on the product page and visible at the time of purchase.  See our Returns Policy for full details on product returnability.

For orders where the item has been received is incorrect, defective or has been damaged in transit, we will pay return shipping and either replace the item or refund the amount paid, at the customer's discretion.

If the reason for the return is different, the customer is responsible for inbound and outbound shipping costs.  Shipping costs paid on the original order are non-refundable.  For orders shipped free on our $99 Free Shipping offer, an amount may be deducted from your refund to cover outbound shipping costs if returned.

Special Orders are normally non-cancellable and non-returnable because a lot of additional work must be performed to obtain a special order part that is not ordered very often.  If we are able to facilitate a special order return, you may have up to a 30% restocking fee deducted from your refund to cover manufacturer restocking fees and other associated costs.

Refunds can only be returned to the same method of payment that was originally used to pay for the order.
