Jakarta (ANTARA News) - About 50 to 60 percent of the lubricating oils circulating in Indonesia are fake, an activist of the Indonesian Anti-Counterfeit Society (MIAP) said here on Wednesday.

"In our investigation we found that more than 50 percent, or even about 60 percent,  of the lubricating oils circulating in Indonesia are fake," MIAP Secretary General Justisiari Perdana Kusumah said.

She said almost all the trade marks of lubricating oils in Indonesia were counterfeited.

More than 50 percent of the fake lubricating oils were circulating in Java as the biggest market, Kusumah said.

"The fake oil is produced in Java so that it is easy for the counterfeiters to distribute their products at lower prices. Of the amount, about 70 percent are sold in Jakarta and Semarang," she said.

In the last three months, police have launched  sweepings on fake commodities in a number of places believed to be used to falsify the products.

The police found that almost all the trade marks of the products  in the country were counterfeited.

In the meantime, international consultant of Rouse & Co. International, Brett Mcguire, said a number of producer companies had admitted that their products had been falsified.

According to MIAP's study in 2005, the losses from the falsification of automotive components and machinery alone reached Rp50 billion.

The need for lubricating oils in Indonesia reached  600 million to 700 million liters per annum, of which 180 million is for industries and
