Once you've used your first oil change kit and are ready to change your oil again, purchase a second kit at your convenience and change your oil.
Then, go to our Returns page to browse the directions, FAQ, and file an RMA by clicking "Submit Lifetime Guarantee Replacement" to return the first kit for a credit of the value of your previous purchase (shipping excluded). If you checked out as a guest, you won't be able to file a return in the portal, so please fill out and include this printable return form instead.
Please also package the oil in either the old oil containers or the new oil containers, then double bag and the fluids then pack them in a sturdy box to prevent leaks along with your return form.
