Oil/Lubricants

High Performance Lubricants by Dart Four

Protect your equipment investments and maximize engine efficiency with our line of High Performance Lubricants by Dart Four. Specially engineered for heavy-duty commercial pressure washers, small engines, and work vehicles, these premium oils and lubricants deliver extreme pressure protection, superior thermal stability, and unmatched resistance to breakdown under harsh jobsite conditions.

I personally use these exact lubricants in all of my own machines and work vehicles—and the results speak for themselves. By reducing mechanical friction, preventing sludge buildup, and standing up to continuous heat and moisture, Dart Four lubricants extend overall engine life and allow for less frequent oil changes, saving you significant time and money on maintenance.

Key benefits of Dart Four lubricants include:

  • Extended Engine & Pump Life: Advanced friction-reducing additives protect vital internal components from premature wear, scuffing, and metal-on-metal contact.

  • Longer Service Intervals: Exceptional resistance to viscosity breakdown and oxidation means cleaner oil that lasts longer between routine oil changes.

  • Corrosion & Moisture Protection: Formulated to resist water emulsion and shield engine parts from rust, salt, and harsh chemical exposure.

Upgrade your maintenance routine with Dart Four lubricants to keep your fleet and equipment running strong for the long haul.
