Top frequently asked questions about the OPS Eco-Pur system

What is the difference between the Eco-Pur and standard full flow filters? 

Standard full flow filters will filter out particulates in the 10-40 micron range, while the Eco-Pur filter will remove particulates down to 3 microns. The Eco-Pur Evaporator removes liquid contaminates that create acid, oxidation, sludge, and dilute oil. The Eco-Pur system refines the oil by removing all contaminants to maintain oil quality and extend additive package life. 

Isn’t the Eco-Pur just another by-pass system?

No. By-pass filter systems have been around for years and for the most part, do a good job removing solid particulates to extend oil life and improve engine protection. However, the oil is still susceptible to the effects of liquid contaminates, corrosion, oxidation, lubricity loss, and sludge. The Eco-Pur goes beyond traditional by-pass filter systems by adding an evaporator that removes the liquid contaminates and extends the useful life of additive packages. 

What harm do liquid contaminants pose to an engine? 

When water mixes with sulfur and heat, acid is formed. Water will also emulsify oil. This reduces lubricity and oil’s ability to properly cool engine components. In addition, water will increase oxidation rates, causing rust and additional wear to engine components. Diesel fuel mixes with oil and thins oil out, reducing viscosity and oil effectiveness. 

What effect does the Eco-Pur have on engine life?

The tolerances between key engine components are damaged by solids in the 10-20 micron range that become trapped between rings, cylinder walls, and bearings. This causes grooving and excessive wear. The Eco-Pur removes these particles and heat retention will keep gaskets, components, and vital parts from premature failure. 

Does the Eco-Pur have any effect on the fuel injection system? 

Modern engines have hydraulically controlled fuel injectors that use motor oil to open and close injectors. The effectiveness of injector operation is negatively affected when the oil is contaminated and oil properties are not consistent. Injectors that do not open or close to specifications will alter fuel to air mixture, thus lowering power and leaking raw fuel into the cylinder, wasting valuable fuel. Keeping the oil free of solids and liquid contaminants maintains proper oil properties. 

Why do I need an on-board refining system to remove liquid contaminants? Isn't engine oil is hot enough already?

Engine oil does create sufficient heat to evaporate liquid contaminants, however, to evaporate completely, the water, diesel fuel, and glycol must be brought to the surface. The oil in the reservoir is in constant motion during operation, which emulsifies water and mixes the diesel fuel and glycol, trapping them in the oil. When vehicles are stopped, the oil will come to the surface, trapping water, diesel fuel and glycol below. Even if the liquids would evaporate they would be contained within the engine block, condensing when the engine cools, and returning to oil. 

Can the ECO-PUR™ cause a drop in oil pressure that might affect engine performance?

No. The standard rate of oil flow required for the ECO-PUR™ to work effectively has little to no effect on oil pressure. The system is designed to maintain pressure until the oil enters the ECO-PUR™ Evaporator and before returning to the oil reservoir. 

How will the ECO-PUR™ affect the oil additives?

When the contaminants are removed from the oil, the additive package remains intact, as there are no diesel fuels washing down oil, acids forming, oxidation, foaming, nor a need for detergents and coagulators to remove particulates less than 20 microns etc. Without water and acid, oxidation does not form. That allows the neutralizers and chemical packages to remain unused. The ECO-PUR™ filtration removes particulates sized 3 microns and above, making it unnecessary for coagulators and detergents etc.The oil sample results will confirm the availability and usefulness of the additive package to ensure the engine receives proper protection from oil. Bear in mind, engines will burn oil and require topping off, this will help to replace additive package as well.

What happens to additive packages manufacturers add in their oils to maintain viscosity, reduce wear, prevent oxidation, foaming and corrosion, disperse solids, and keep surfaces free of deposits, when oil drains are extended?

The additive package formulated into modern oils to improve viscosity, neutralize acid, eliminate corrosion and oxidation, to keep oil clean, and, to prevent foaming, is depleted during normal engine operation as oil becomes contaminated with solid and liquid contaminants. Extending oil change intervals without an on board oil refiner will lead to depletion of the additive package, resulting in damage to the engine. The use of an on board oil refining system allows for the extension of oil drain intervals by removing the root causes of the damage causing conditions, for which the additives are intended to provide protection. 

Will the installation of the ECO-PUR™ affect the manufacturer's warranty? Doesn't the engine manufacturer require oil changes to keep the warranty enforced?

No, installation of the ECO-PUR™ does not affect the manufacturer's warranty. There is a common misconception that engine warranties will be voided if oil is not changed at periodic mileages recommended by manufacturers.The obligation of the engine owner is to properly maintain the oil quality to lubricate the engine. The engine manufacturer will not honor a warranty claim if oil is not within guidelines and specifications. Changing oil does not guarantee a warranty claim will be honored.The ECO-PUR™ will maintain oil quality within guidelines for extended periods. and the oil sample results will provide a written record of oil quality. The engine manufacturer will request an oil sample to evaluate the oil quality to ensure the engine was not abused by failure to maintain adequate oil volume, overheating, intentional abuse etc, before they will approve claim. Changing oil on a periodic basis does not prevent this type of damage, and the claim will be declined. Sampling requirements may vary by engine manufacturer. OPS suggests that our customers consult with OEM for specific information.
