SHPD (Super High Performance Diesel) and UHPD (Ultra High Performance Diesel) oils are designed for powerful diesel engines, but have some differences:
Quality and performance:
SHPD (TS-1, TS-2, TS-4) oils provide high performance and stability under severe operating conditions. They have good detergent and antioxidant properties.
UHPD (TS-5, TS-6, TS-7, TS-14) oils represent the next level of quality, providing even higher performance and engine protection. They are designed for the most modern and powerful diesel engines.
Drain intervals:
SHPD oils usually have an extended drain interval, which allows them to be used longer without losing quality.
UHPD oils have an even longer drain interval, which makes them more economical in the long term2.
Specifications and standards:
SHPD oils meet ACEA E3/E5/E7 and API CF-4, CG-4 standards.
UHPD oils meet higher standards such as ACEA E4/E5 and API CH-4, CJ-4.
These differences make UHPD oils preferred for use in the most modern and demanding diesel engines, while SHPD oils are suitable for a wide range of severe operating conditions.
