Protect Your 2019+ 6.7L Cummins From Lifter & Cam Wear

A lifter tick can turn into metal in the oil and a massive repair bill. Diamond NanoLube is engineered to support lubrication at the lifter/cam interface—where 5th-gen Cummins engines are most vulnerable.

  • Supports boundary lubrication during cold starts + towing loads

  • Works with OEM-spec 10W-30 (no viscosity change required)

  • Easy dosing: 3 bottles per oil change (typical 12-quart sump)

Why 2019+ 6.7L Cummins Lifters Need Extra Protection

Factory hydraulic lifters rely on tight clearances and small oil passages. Cold starts, heavy loads, and long intervals can stress the oil film at the lifter/cam contact point. If a lifter fails, metal can circulate through the oil—risking damage to the cam, bearings, and turbo.

Preventive protection is cheaper than repairs.

How Diamond NanoLube Helps

  • Boundary lubrication support
    Boosts protection at the lifter and cam lobes—especially at cold start and under load.
  • Supports consistent oil flow
    Helps maintain cleaner, freer-flowing lifter oil passages for more consistent lubrication.
  • OEM-friendly
    Works with OEM-spec 10W-30 so you can stay within factory recommendations.

This product is a preventive protection aid. It does not repair damaged lifters/cams and cannot guarantee against all failures.
