why clean & dry oil is a must

Research shows that 80% of oil related failures and breakdowns are caused by contaminated oil!
Preventive oil maintenance is therefore an important factor to ensure optimum equipment reliability and avoid system breakdown.

With CJC® Oil Filters installed, you ensure continuous clean and dry oil, increase uptime, extend component and oil lifetime, resulting in savings on your maintenance costs. All of which leads to reduced environmental impact due to many litres of waste oil saved every year.
