Chevron Delo® 400 and Delo® 600 ADF: Get the Right Oil for Your Job and Save Money

At RV Jensen, we recognize that performance is number one when it comes to choosing the best oil for your heavy-duty hauls. The right engine oil protects your investment, extends drain intervals, and cuts unplanned downtime. That is why we stock Chevron Delo 600 ADF and Delo 400 for today’s diesel and mixed-fleet needs.

Why Chevron Delo® Heavy-Duty Engine Oils?

These innovative oils dynamically increase fuel efficiency and optimize drain intervals, resulting in extended engine life.

Delo 400 and Delo 600 ADF are formulated to help you:

• Go more miles on the road between maintenance intervals
• Increase uptime across seasons and duty cycles
• Protect engines in extreme conditions and mixed service
• Lower fuel and maintenance costs to reduce the total cost of ownership

Both lines are engineered for modern emissions-control systems, including DPF, EGR, and SCR, and are compatible with GHG 17 on-highway engines. Always follow your OEM recommendations.

Chevron’s Delo oils are workhorses across multiple industries—from gas and oil, to construction, to agriculture—ensuring emission standards are met. They fit the job.

Start at the Top: Delo® 600 ADF for Optimized Drains and DPF Protection

If your fleet runs modern diesel with DPFs, Delo 600 ADF is the premium choice. Its OMNIMAX® ultra-low-ash formulation helps reduce ash loading in the DPF and extends DPF service intervals by more than 2.5 times, while supporting long-drain service when approved by your OEM and verified by oil analysis. It also helps retain fuel economy over time.

Why it matters: less ash means fewer manual DPF cleanings, less downtime, and better fuel-economy retention across the service interval.
