Technical Support

Dedicated to ensuring customers receive the finest products and the greatest value.

Our technical staff is unmatched in its capability to guide you, whether your questions refer to products, applications or processes.

In Base Oils, we have a long history of helping compounders and blenders arrive at the most productive oil for their prospective applications.

In Process Oils, we offer an exclusive perk, our own Rubber Lab. It’s rare for an oil company to have a rubber chemist on staff, and even more rare to put a state-of-the-art Rubber Lab at his disposal. Fully equipped with $2,000,000 in rubber compounding and testing equipment, the Lab enables HollyFrontier’s experienced professionals to experiment with, and recommend the most effective combinations of oil and rubber characteristics to meet your performance requirements. Whether compounding, testing or analyzing, our chemists will work with you in trouble-shooting existing compounds for improvements, or in developing new products entirely. In Agriculture and Asphalt, our technical staff is up to date in helping you use our oils to improve your applications. They know what our products can contribute, and they have the experience to help you find the solutions that best enhance performance.
