10W-40 UHPD engine oil for heavy-duty diesel engines with a long-drain focus and E4/E7 profile for extended service intervals.
10W-40 UHPD is designed for heavy-duty diesel applications where extended service intervals, high mileage, and stable oil performance are key priorities. The product is intended for trucks, buses, and machinery requiring E4/E7 and UHPD performance levels.
The UHPD concept stands for ultra high performance in heavy-duty operation. This includes excellent fuel economy properties, strong load reserves, reliable protection against corrosion and black sludge, and the ability to technically support long service intervals within approved limits.
For fleets with high annual mileage, this is a significant economic factor. Reduced downtime, fewer oil changes, and stable lubrication performance under heavy load make 10W-40 UHPD a clearly positioned long-drain oil.
Suitable for heavy-duty diesel engines in trucks, buses, and machinery where long intervals and corresponding UHPD/E4/E7 approvals are required. Particularly relevant for long-haul transport, continuous operation, and demanding heavy-duty use.
What does UHPD mean in 10W-40 UHPD?
UHPD stands for Ultra High Performance Diesel and describes a heavy-duty oil for long intervals and very high engine requirements.
Are 80,000 to 120,000 km always achievable?
No. Such intervals always depend on manufacturer approvals, operating conditions, oil monitoring, and fleet strategy.
Is this oil only intended for long-haul transport?
Not exclusively, but that is where its long-drain characteristics offer the greatest economic benefit.
