OIL CAN TALK. We understand the message. OELCHECK understands the message of the oil. You will receive objective and competent information about the condition of the lubricant and the machine. Our laboratories are completely independent and lubricant analyses are our only business. OELCHECK isone of the leading laboratories for lubricant analyses throughout Europe. Founded in 1991 under the name of WEARCHECK, our company is still a family-run business and completely independent. We are steadily expanding our business and our laboratories in Germany and South-China are state-of-the-art. We are investing continuously in innovative test equipment and intelligent software. Our employees are recognized experts in their field and provide accurate diagnoses comments. With the help of several physical and chemical values, OELCHECK can find out detailed information about the oil condition and the machine and support you to work out the optimal oil change intervals. Certain wear particles can be allocated to specific worn out machine parts and therefore function as an early indicator regarding possible damage. Oil from construction machines, industrial facilities, cars, trucks, gearboxes or hydraulic systems – OELCHECK analyses all lubricants including many fuels and understands the message!
