The following are questions that have been asked regarding our processes and we are responding to them as Frequently Asked Questions. We hope they are helpful to you in deciding if this is the business for you.

Question: What technology should I use to re-refine used oil?


The Interline process makes all other re-refining processes obsolete. It is the most innovative technology available on the market today to re-refine used oil, from both an economic standpoint and quality assessment. 70% of all lubricants in the United States are produced from group l base stocks; 90% of all other lubricants produced elsewhere in the world come from group l base stocks. Major oil companies are pushing group ll and group lll base stocks, but their acceptance and pricing has been slow.

The Interline process is broken down into three simple steps: pre-treatment, solvent extraction, and vacuum distillation. There are no other finishing steps required to complete or perfect the Interline base oil. All other processes that are commercially proven use a combination of thermo-destruction or thin film distillation to separate the contaminates from used oil, which requires additional extensively complicated steps such as fixed-bed catalytic hydro treating, clay treatment and chemical additions to improve the oil. In addition to hydro treating, these added processes also require fractional distillation. The cost of hydro treating and fraction distillation as finishing steps is exceptionally expensive and is only reserved for large refineries.

The Interline concept is to build small 24,000 gallon/day refineries which exploit local oil supplies and sell into regional markets, thereby reducing transportation costs. The quality of the base oil produced from the Interline process is the equivalent of group l+ oil in chemical characteristics. Licensed products can be produced from Interline’s base oil. The base oil produced from the process, passes IP336 and the Modified Aims Test, which is a Mutant Genicity test aimed at identification of cancer causing carcinogenic agents. Even hydro treated base oils from other processes cannot make this claim. Simply stated, re-refined oil is based on two items: odor and color. Interline’s oil smells like regular virgin base oil and has a color and quality as though it had been hydro treated.

Question: What are the major considerations in building an Interline refinery?


The viability of operating a profitable Interline refinery rests on three pillars: 1) oil collection 2) successful operation of the refinery with competent operators and 3) reliable finished product markets. The cardinal rule for economic re-refining is this: only install and operate the minimum amount of processing equipment which allows the waste oil to be upgraded to the highest lubricant oil product that can be sold profitably. Stated another way, it is simply not profitable to add additional processing steps in an attempt to improve the quality of the re-refined oil beyond the specifications required by your resale market. The fact that it is re-refined base oil will always be reflected in the pricing of the re-sale markets unless the base oil is compounded and sold as lubricants.
