Some further testing was done extending the kilometres between oil changes and this did show a deterioration in the performance of the oil. When tested the oil showed high metal contents indicating engine wear.
2. Yes, as part of the evaluation, the Manager of ACT Plant Workshops contacted Ford Australia, Issue Australia, Caterpillar Australia, Detroit Engines and sought their comments of the use of recycled oil. These convents are summarised as follows:
. Ford Australia indicated that they could not recommend the use of recycled oils as they had experienced problems due to slugging which in several cases resulted in early engine failure.
Issue Australia could not recommend the use of recycled oil as none of the recycling companies had their oils tested and met current American Petroleum Institute (API) or American Military specifications. They indicated that recycled oils had created slugging and that there were problems in removing the existing additives from the oil in remanufacturing or recycling. They did not recommend it on the basis that there was no consistency in the oil bases.
Caterpillar Australia indicated the oil had not been tested but did not meet current API classifications and until these were met, the oil would not be recommended.
Detroit Engines indicated that their requirements were very strict and that only oil which met API and military specifications would be acceptable to their engines.
All the companies that the Plant and Workshop Manager spoke to indicated that until remanufactured or recycled oil met current API and military specifications they would not be recommending its use. He also spoke a representative of a major oil company who indicated that from their experience there were grudging problems with recycled oil particularly in the smaller diesel and petrol engines.
3. No, as our efforts have been directed to Trillium Pty Ltd which is the major remanufacturer of oil within Australia. There are other companies which recycle oil by purely filtering it, but only produce oil in very small quantities. Trillium, through a range of distribution companies, are the major supplier to the Australian market.
