A description of the technology to be certified, the final certification statement and the certification limitations follows.

TF PURIFINER, INC.
ELECTRIC MOBILE OIL REFINER

Technology Description

The Electric Mobile Oil Refiner is a bypass engine oil filtration system which is intended to extend oil drain intervals. The system consists of a canister that can be mounted on the fire wall, fender well, or frame of a vehicle. The canister inlet is connected to the engine's oil pressure sending unit and the outlet to the engine crank case. The canister houses a disposable cotton filter element and an evaporation chamber in order to remove fuel, water, and coolant which are vented into the air cleaner. The filtered oil then flows back into the engine by gravity flow.

Certification Statement

The Electric Mobile Oil Refiner is hereby certified by the California Department of Toxic Substances Control (Department) as a Pollution Prevention technology when installed, operated, monitored, and maintained according to TF Purifiner's standards and specifications. This pollution prevention certification is specific to engine oil usage and used oil generation (no life-cycle analysis was performed). The Electric Mobile Oil Refiner has been shown to be an effective means of extending engine oil change intervals by aiding in the removal of particulates, water, coolant, and dissolved fuel. Extended drain intervals reduce: 2) use of new oil, 2) generation of used oil, 3) potential of spills while draining and transporting used oil, and 4) maintenance time and expense to operate and manage engine oil changing facilities.

The Electric Mobile Oil Refiner has been shown to be capable of maintaining the following engine oil properties within acceptable limits for continued use when operated, monitored, and maintained in accordance with TF Purifiner's standards and specifications: viscosity and the content of solids, water, coolant, fuel, wear metals, and oil additives. The engine drain cycle for differing vehicles may depend on the engine type, fuel quality, oil type, oil consumption, and loading of engine.

Certification Limitations/Disclaimer

The Department makes no express or implied warranties as to the performance of TF Purifiner's product or equipment. Nor does the Department warrant that the TF Purifiner's product or equipment is free from any defects in workmanship or material caused by negligence, misuse, accident or other causes.

The Department does believe, however, that the manufacturer's product or equipment can achieve performance levels set out in this certification. Said belief is based on a review of the data submitted by the manufacturer and interviews with end-users of the equipment when the product or equipment was used in accordance with manufacturer's specifications. Limited testing was conducted under the direction of the Department to confirm the data submitted by TF Purifiner or collected from other sources.

This certification is issued as part of the pilot project for the California Environmental Technology Certification Program The pilot project purpose is to delineate the practical aspects of the program that will be adopted in regulations which are under development. Consequently, this certification may be subject to additional conditions which will be required in these regulations, including, but not limited to, the duration of the certification, continuing monitoring and oversight requirements, and certification amendment procedures, including decertification.

By accepting this certification the manufacturer assumes, for the duration of this Certification, responsibility for maintaining the quality of the manufactured equipment and materials at a level equal or better than was provided to obtain this Certification and agrees to be subject to quality monitoring by the Department as is required by the law under which this Certification is granted.

TF Purifiner provided copies of letters from seventeen engine manufacturers which discussed the effect of using an Electric Mobile Oil Refiner on their respective engine warranties. The responses were similar and generally could be summarized as follows:

The original engine warranty covers defects in workmanship and/or materials as manufactured and use of after-market devices, such as the Electric Mobile Oil Refiner, does not, in and of itself, void the warranty. However, any engine performance problem or failure attributable to use of such devices will not be covered under the terms of the warranty.

If there is a question concerning engine warranties, the end-user should consult their particular engine manufacturer to determine if using the Electric Mobile Oil Refiner will affect their engine warranty.

Certification Basis

The State of California reviewed the engine oil analyses supplied by TF Purifiner for two of the end-users of the Electric Mobile Oil Refiner. These as well as eleven other end-users were interviewed regarding their experience with the Electric Mobile Oil Refiner. The interviews included discussions of number of units used, years of experience with product, vehicle/engine types, model year of vehicles, mileage on vehicles while using the Electric Mobile Oil Refiner, oil filter change intervals, oil drain intervals, oil consumption rates, engine load factors, engine maintenance/repair records, and satisfaction/dissatisfaction with product.

The diesel truck applications included:

  • One fleet of 18 trucks with an average of over 800,000 miles per truck without changing the oil;
  • One fleet of five trucks, each with over 300,000 miles per truck without changing the oil;
  • Two fleets with a total of 15 trucks, each with over 200,000 miles between oil changes;
  • Four fleets with a total of 52 trucks, each with 90,000 to 150,000 miles between oil changes; and
  • Two fleets with a total of four trucks, each with 80,000 miles or less on the oil without an oil change.

The marine applications included:

  • Two main engines with oil change intervals greater than 10,000 hours (the engines were not rebuilt until over 60,000 hours of operation);
  • Two nine-year old generator engines with oil change intervals greater than 1,500 hours; and
  • Two nine-year old main engines with oil change intervals greater than 1,500 hours.

In the hydraulic press application, the oil has not been changed since 1981; prior to installing the Electric Mobile Oil Refiner, the oil was changed after every 1,000 hours of operation with an average usage of 1,300 hours per year.

TF Purifiner offers a ten year warranty on the Electric Mobile Oil Refiner. This warranty includes repairs or replacement of the product itself and also repair of damage to engines caused by the Electric Mobile Oil Refiner during the ten-year warranty period. This warranty is limited as specified in TF Purifiner's warranty statement.

System Specifications

Electric Mobile Oil Refiners come in six different sizes depending on oil sump capacity (8,12,24,40,60, 240 quarts). The devices can also be used in multiples for extra large sumps. The Electric Mobile Oil Refiner comes with all the mounting brackets, stainless steel hardware, aircraft quality hose fittings, and complete instructions for installation and maintenance of the unit. Replacement filter elements and other optional equipment are sold separately.

Operation and Maintenance Requirements

In engine applications, TF Purifiner's servicing recommendations state that the Electric Mobile Oil Refiner's filter element should be replaced every 12,000 miles or 300 hours or as oil analysis dictates. TF Purifiner's servicing recommendations also state that the standard full-flow oil filter should be replaced once per year under normal conditions for their smallest unit (designed for engines with eight-quart oil sumps or less) and twice per year or every 60,000 miles for all other units. TF Purifiner's warranty, however states, among other conditions, that the warranty will be honored if: 1) filter elements are replaced at the same intervals that oil changes were performed prior to installation of the electric mobile oil refiner, and 2) engine oil analysis is performed by a qualified laboratory when the electric mobile oil refiner's filter elements are replaced.

In transmission and hydraulic applications, TF Purifiner's installation instructions note that the Electric Mobile Oil Refiner's filter element life is greatly extended and it can be replaced every 1,000 hours or as oil analysis dictates.

Regulatory Considerations

California Air Resources Board (CARB) -- CARB has determined that installing the Electric Mobile Oil Refiner will not "reduce the effectiveness of the applicable vehicle pollution control system and, therefore is exempt from the prohibitions of Section 27156 of the Vehicle Code for installation on all 1993 and older model-year vehicles with pressure oil systems."

Used oil and oil filter elements are presumed to be hazardous wastes, unless determined to be non-hazardous, and must be properly managed. The used oil filter elements may be crushed in such a way as to recover any resulting used oil and then recycled for metals recovery without obtaining a hazardous waste treatment permit. Used oil from extended drains and from crushing of oil filter elements must be transported to a permitted used oil recycling facility.
