Maximize Your Equipment Life With Chevron ISOCLEAN® Certified Lubricants

Clean. Redefined.​

Chevron ISOCLEAN Certified Lubricants Program

Did you know that particle contamination is the number one cause of lubricant-related equipment failure? And that contamination causes an estimated 82% of component wear?

Tiny foreign particles just 4 microns in diameter can compromise lubricant effectiveness and cause significant expense for equipment repair, premature replacement and lost revenue due to downtime.

The Chevron ISOCLEAN Certified Lubricants Program helps you maintain a clean system, control lubricant contamination and maximize equipment life, while reducing costly maintenance and downtime.

ISOCLEAN Certified Lubricants are specially filtered and guaranteed to match the original equipment manufacturer’s (OEM) cleanliness recommendations and ISO cleanliness codes. Every batch is certified at your point of delivery, so you know it’s right for your equipment.

ISOCLEAN Services are designed to help you analyze your onsite procedures and contamination controls and, if necessary, clean up and manage contamination of in-service lubricants and operating systems.

As a Chevron ISOCLEAN Certified Lubricant Marketer, Woodford has the products, services, knowledge and expertise to help you:

  • Increase component life
  • Increase uptime
  • Improve machinery reliability
  • Improve product quality
  • Improve safety
  • Reduce service time

What Causes Particle Contamination?

Every time a lubricant is handled, there is an opportunity for particles to creep into the oil: airborne particles, dirt, silicate, paint, water.

Even fresh lubricants can suffer contamination—for example, when shipped from a manufacturing plant, trucked to a distributor’s storage facility, pumped into a delivery truck, transferred to a customer’s storage tanks, or poured into the equipment’s system.

Check out this ISOCLEAN 101 presentation to learn more about particle contamination and how to manage it.

ISOCLEAN Certified Lubricants give customers the opportunity to significantly extend equipment component life by 2 to 4 times in most cases.

ISOCLEAN Calculator

Use Chevron’s simple, three-step ISOCLEAN Calculator to estimate the current lifespan of your equipment components versus what could be achieved using ISOCLEAN Certified Lubricants.

And keep in mind that controlling fluid contamination at the start will save you 90% of the cost to remove it later—when considering the cost of component repair together with lost revenue while the equipment is out of service.

Understanding ISO Cleanliness Codes

In support of managing lubricant cleanliness, the International Organization for Standardization (ISO) developed the standardized ISO Cleanliness Code 4406:99 that is the primary piece of reporting data used to measure fluid lubricant cleanliness. The code defines how contaminating particles are sized and counted.

OEMs usually include ISO fluid cleanliness recommendations in their equipment manuals. However, not all end users are aware of their equipment’s cleanliness specifications. And those who are aware may not have access to the necessary facilities to measure their lubricant contamination levels. Often, it is only after doing a fluid analysis that the user discovers that the level of particle contamination in the oil may be putting their equipment at risk.
