Ladies and Gentlemen:

We have acted as counsel to United Refining Company, a Pennsylvania corporation (the “Company”), and the Subsidiary Guarantors (as defined below), in connection with the Registration Statement on Form S-4, as amended (File No. 333-121348) (the “Registration Statement”), filed by the Company with the Securities and Exchange Commission, pursuant to which the Company is registering (i) $200,000,000 aggregate principal amount of its 10 ¹/2% Senior Notes due 2012 (the “New Notes”), to be exchanged for the Company’s outstanding notes bearing substantially identical terms and in like principal amount (the “Old Notes”) in a registered exchange offer (the “Exchange Offer”) and (ii) the guarantees (the “Guarantees”) of each of the guarantors listed on Schedule I hereto (the “Subsidiary Guarantors”) of the New Notes. The Old Notes were issued, and the New Notes will be issued, under an Indenture dated as of August 6, 2004, among the Company, the Subsidiary Guarantors and The Bank of New York, as trustee (the “Indenture”).

We have made such inquiries and reviewed such documents and records as we have deemed necessary or appropriate as a basis for our opinion. We have also examined and relied upon representations, statements and certificates of public officials and of officers and other representatives of the Company. In rendering our opinion, we have assumed that the New Notes have been duly and validly authorized by all necessary corporate action on the part of the Company, and that the Guarantee of each Subsidiary Guarantor incorporated in the State of Michigan, the State of Ohio or the Commonwealth of Pennsylvania has been duly and validly authorized by all necessary corporate action on the part of each such Subsidiary Guarantor.

Based on the foregoing, and subject to the qualifications, limitations and assumptions set forth herein, we are of the opinion that, when the New Notes and the Guarantees have been duly executed, authenticated, issued and delivered in accordance with the provisions of the Exchange Offer and the Indenture, (i) the New Notes will be legally issued and constitute binding obligations of the Company, and (ii) the Guarantee of each Subsidiary Guarantor will be legally issued and constitute the binding obligation of such Subsidiary Guarantor.
