The Fleet Prescription.
Move beyond price per litre. Unlock hidden value in your fleet with a comprehensive Lubrication Audit.
TRUSTED BY NEW ZEALAND HEAVY TRANSPORT
Total Cost of Ownership (TCO).
Buying on price per litre is short-sighted. Real savings are found in efficiency, drain intervals, and fuel economy. Vertex acts as a technical partner, not just a supplier. We audit your entire fleet to identify where the right product can deliver fuel savings that far outweigh the marginal difference in oil price.
The 4 Pillars of Analysis
Every audit delivers insights across these critical areas

Inventory Consolidation
We map every asset to identify overlaps. Reducing stock holding frees up capital and reduces misapplication risk.

Fuel Economy optimisation
Switching to low-viscosity engine and driveline fluids can reduce fuel spend without compromising protection.

Drain Interval Extension
Through oil analysis and premium chemistry, we safely extend service intervals to keep trucks on the road and machines operating for longer.

Warranty Compliance
Every recommendation is cross-referenced against OEM requirements to ensure your warranty remains intact.

Case Study
Nuance Matters.
Because Vertex holds the widest lubricant range in New Zealand, we don’t force a “near enough” product into your machine. We have the expertise to analyse OEM requirements alongside customer goals to curate a recommendation for specific Low-Viscosity or Fuel-Economy fluids that others simply can’t.

The Challenge
Reducing diesel spend — one of the biggest operating costs for fleet operators.
The Fix
A shift to Low-Viscosity Engine Oils and Fuel Economy Driveline Fluids matched to duty cycles, paired with additional driver training and monitoring.
The Result
The fuel savings alone covered the cost of the entire lubrication program. The oil effectively paid for itself.
