  • Klass Oil has been a supplier to the Delvin/Clonmellon Purchasing Group over the past 10 months. As a well-established agricultural organisation, we have dealt with many different suppliers over the years and we are happy to say that we are extremely satisfied with Klass Oil. Their customer service is second to none, which is important for both the group committee as well as individual members.
