Mobil 1 National 2026 Sweepstakes: enter with motor oil purchases or mail-in entry

Why this promotion is worth checking

Mobil 1’s National 2026 Sweepstakes is best suited for drivers who already plan to buy motor oil or schedule an oil change, but the rules also include no-purchase entry. Because there are several entry routes, the value here is in following the right path, not rushing through the form.

The purchase-based methods center on a qualifying Mobil 1 purchase, typically five quarts or more, or a qualifying oil change. The official rules separate standard retail purchases, O’Reilly purchases and installed-location purchases, so the documentation and mailing address can vary by route.

How to participate step by step

1. Review the official rules to choose the entry route: online with purchase, mail-in with purchase, O’Reilly purchase route, installed-location route or no-purchase option.
2. If entering with purchase, buy the qualifying Mobil 1 product during the sweepstakes period and keep the receipt.
3. Circle the qualifying purchase if mailing documentation, or upload/submit the receipt as instructed by the promotion site.
4. If entering without purchase, follow the official mail-in AMOE directions exactly.
5. Submit by the correct deadline and keep copies of purchase or mailed materials when possible.

Requirements to check before entering

• Legal resident of the 50 U.S. or D.C. who meets the age of majority requirement and is at least 18, or 19 in Alabama or Nebraska.
• No purchase is necessary and a purchase does not increase chances of winning.
• Purchase entry generally requires five quarts or more of eligible Mobil 1 motor oil or an eligible Mobil 1 oil change.
• Puerto Rico, Guam, the U.S. Virgin Islands and other U.S. territories are void under the rules.

Important notes from the official rules

• The sweepstakes runs from May 1 to August 31, 2026.
• The rules list several entry methods, so the correct address or form depends on how the qualifying purchase was made.
• Universal Pictures is referenced as not administering the sweepstakes; questions should go to the sponsor, not the Universal parties.

Before submitting, verify the retailer, product quantity, receipt date and whether your entry method requires upload or mail. A receipt sent to the wrong route or missing required information can cost you the entry.
