New oil filtration improves on current maintenance

by Katy de Vries

STRATHROY, Ont. – Canadian truckers may soon be able to forget the lessons learned about changing engine oil thanks to a Swedish technology recently introduced to the North American market.

The COT oil processor is an oil bypass filtration system that removes both solid and liquid contaminants in the engine oil, according to John Aarts, sales and marketing for COT North America.

“There are many SAE papers that say engine oil never mechanically wears out, it just gets dirty,” said Aarts. “So the idea is that if the oil can stay clean it will continue to protect your engine and extend its life by two to three times.”

Foreign particles and liquids contaminate oil over time, resulting in engine wear and eventual failure.

According to Aarts, the benefits of rejuvenating engine oil are a reduction in oil consumption by 90 per cent and reduced handling and storage of oil as well. There is no need for used oil disposal so it is a more environmentally sound method of engine operation. Increased engine efficiency means lower fuel consumption and fewer exhaust emissions, and prolonged engine life means financial savings.

“Someone had to invent the wheel and now this product’s time has come. I think they have developed a product that could revolutionize the trucking industry, it’s just a matter of time,” said Aarts.

As with any new technology, there will be some skepticism, he acknowledged.

“Everyone has been taught to change engine oil regularly if you want an engine to last – we are going against the grain. But once people accept that this product does exactly what we say it does then over time we will win them over,” Aarts said.

Generally speaking, a highway truck requires an oil change every 20,000-km. With the COT oil processor, this isn’t necessary, according to Aarts.

“You will never need to actually drain and change the oil, but you may need to top it up a little when you change the filters because some oil will be lost with the filters,” he said.

The oil enters the filter unit at a measured flow rate under pressure supplied by the oil pump and at this stage solid contaminants, such as soot, dirt, silicon, carbon or metal particles, are filtered down to one micron in size.

During the second stage, the oil enters a heated evaporation unit and here the liquid contaminants such as antifreeze, fuel or water, are ventilated out of the system. After the oil goes through both processes, it is clean and is fed back into the engine system by gravity, Aarts explained.

Standard full flow filters screen solid metal particles down to about 25 microns in size, but 90 per cent of all particles in the oil are smaller than five microns, and these particles still circulate through all moving parts of the engine. Since the COT oil processor filters the oil even further and removes particles down to one micron, it creates significantly cleaner oil, said Aarts.

The processor is designed to fit any type of large capacity diesel truck engine, will work with any type of mineral or synthetic oil and will operate in any type of climate or working conditions, say company officials.

The COT oil processor costs about $750 but Aarts claims it will pay for itself quickly with the savings on oil changes and regular maintenance. It also increases the resale value of the equipment, he said.

COT North America is also offering a money back guarantee on the product.

“It is a product that should last you a lifetime,” said Aarts. “If it ever stops working we will replace it.”
