Mystik’s New Heavy-Duty Moly Grease Explained — Watch Our Interview

At Conexpo-Con/Agg 2026, I sat down with Bridget LaFollette to talk machine grease. LaFollette is a marketing manager at CITGO Petroleum Corp. — the Texas-headquartered petrochemical titan specializing in everything from lubricants to fuels. We discussed a variety of topics, including how harsh jobsites break down equipment, why grease is so important for lubrication and sealing, and advice for equipment mechanics and fleet masters. Watch it all in the video above. LaFollette also discussed the company’s new heavy-duty moly grease. In March, CITGO announced its JT-6 Heavy Duty SynBlend 460 Moly Plus #2 (HD460 Moly Plus #2) grease under its Mystik Lubricants line. This new grease specifically targets severe-duty environments common to construction and mining — places where dust, debris, water, and worse challenge operations.

“Grease is really one of the first places you’re going to see an issue if you’re not applying it right,” says LaFollette in the video. “Grease faces a ton of challenges in the construction industry. You have things like shock loading. You’re loading a whole truck, you know, suddenly you dump in a bunch of dirt and your metal-to-metal [contact] gets closer than it should be … You’re in an environment that is full of dust. It’s full of dirt. If that gets into the grease, you can have bearings seize up and that’s never good. Also, wet environments. So, if your grease washes out, that metal-to-metal contact, then you’re replacing your pieces of equipment.”

How does Mystik JT-6 Heavy Duty SynBlend 460 Moly Plus #2 work?

HD460 Moly Plus #2 is the latest product in CITGO’s premium line of JT-6 greases. This product is formulated using molybdenum disulfide or just “moly” for short. Moly is an inorganic compound used in extreme pressure lubricants to provide lubrication and protection in harsher-than-normal conditions such as high temperatures and pressures. CITGO even notes that HD460 Moly Plus #2 “delivers enhanced load-carrying capability and thermal stability beyond traditional moly-based greases” in this press release. It does that by mixing in a lithium-complex thickener and a synthetic-blend ISO 460 base oil to support extreme pressure protection. A 500°F dropping point supports hot-running components, while the formula resists water washout and spray-off. Low oil separation helps it stay where you put it. HD460 Moly Plus #2 is built to protect slow-moving, high-load components like pins and bushings, but it also performs across broader applications when specified correctly.

If this topic hits home, read our recent deep dive on how to properly lubricate equipment components. CITGO is quoted. It breaks down greasing technique, intervals, and common mistakes that lead to premature wear and downtime. Better lubrication equals longer life, fewer failures, and less money left on the jobsite. And that’s worth more than a cheap tube of grease.
