Refund policy

Returns
You have 30 days from the delivery date to request a return.

Returns are accepted only if the product is unopened, in the original sealed container, and in sellable condition, with proof of purchase. Opened, used, or contaminated lubricants cannot be returned, except when the product is defective or we shipped the wrong item.

Email support@coolblueoil.com before you ship anything back. If we approve the return, we will send instructions and, when we cover shipping, a label. Packages sent back without approval will not be refunded.

Damaged, defective, or wrong item
Inspect the order when it arrives. Contact us immediately with photos and the order number. We will replace the item or refund it. You should not pay return shipping for a defect or a picking error.

Change of mind (unopened)
If you simply ordered the wrong viscosity or size, we may approve a return of unopened product. Return shipping is the customer’s responsibility unless we say otherwise in writing.

Exchanges
We do not process exchanges. Return the unopened item for a refund, then place a new order for the product you need.

Refunds
After we receive and inspect the return, we refund the original payment method. Banks can take several additional days to post the credit. Original outbound shipping is not refunded unless the return is our error.

What we do not accept
Opened containers, missing caps or seals, products held past 30 days, and items returned without a prior request.
