Bumper-to-Bumper Protection for Heavy-Duty Vehicles with Caltex Delo®

Imagine a fleet of heavy-duty vehicles whether haulage trucks or construction equipment —each component, from the engine to the gears, is exposed to constant stress, heavy loads, and harsh conditions. Each part of these vehicles needs to be properly lubricated and ignoring any can bring everything to a grinding halt, causing costly downtime and endless repairs. That's where true bumper-to-bumper protection makes all the difference.

Caltex’s Delo® range of products isn’t just a collection of lubricants; it’s a holistic shield for every critical part of your vehicle, designed to work in unison to help avoid breakdowns, reduce maintenance frequency, and save money. Here’s a breakdown of how each Delo® product can contribute to significant long-term savings, fewer repairs, and smoother operation. 

Engine Oils: Clean Engines, Fewer Oil Changes
Delo® engine oils, powered by ISOSYN® Technology, a proprietary technology unique to Delo and is a blend of its premium base oils and high-performance additives with Caltex’s formulation expertise resulting in the provision of outstanding equipment parts protection and performance needed, go beyond simple lubrication to keep engines free from harmful sludge and deposits. This not only keeps engines running smoother but extends the intervals between oil changes. Delo premium range engine oils confers the high degree of soot dispersancy required to maintain oil drain intervals in modern engine designs. Its multigrade viscosity provides additional protection against wear at start-up and under high temperature operating conditions.

• How It Saves: Fewer deposits mean extended oil life and less frequent maintenance, saving on labor and parts while boosting fuel efficiency.

Coolants: Avoiding Overheating Disasters
Heavy-duty engines face tough conditions, and without proper cooling, they’re prone to overheating. Delo® coolants protect against winter freeze-up and summer boil over and prevent corrosion, safeguarding radiators and other sensitive parts. The Delo XLC Antifreeze / Coolant provides a service life of 960,000 kilometers/12,000 hours/ 6 years with no extender needed. It requires no regular testing with proper top-up practices and helps eliminate the need for supplemental coolant additives.

Transmission Fluids & Gear Oils: Smarter Shifting, Smoother Rides

Delo® transmission fluids ensure your transmission components are ready for high-stress demands, reducing gear friction and wear for a longer-lasting, reliable powertrain. Delo SYN ATF HD provides outstanding oxidation resistance and thermal stability that prevents acid buildup, oil thickening and deposit formation and can extend oil drain intervals up to four times that of conventional ATF.

• How It Saves: Parts inside the gearbox are safe from wear and tear, reduced sludge build-up, leakage prevention through maintained viscosity lead to fewer repairs and replacements, which lowers both costs and downtime.

Greases: Tough on Stress Points

Delo® greases protect high-pressure parts like bearings and pivot points, standing up to extreme conditions to keep components functioning at their best. Delo Starplex EX protects metal surfaces even in conditions of severe water exposure. Its high dropping point minimizes leakage from bearings at elevated temperatures and excellent oxidation resistance ensures long grease life.
