Comparative analysis of UHPD and RINNOL OLGER PREMIUM 10W-40 engine oils

The short verdict:
Both oils belong to the UHPD (Ultra High Performance Diesel) category and they are high-quality products for modern diesel engines with extended service intervals. They are completely interchangeable for machinery, requiring compliance with ACEA E4, API CI-4 specifications and other specified tolerances. However, there are key differences in their chemical composition that affect their properties.

Detailed parameter analysis

1. Basic specifications and tolerances

It’s a complete coincidence: Both oils have identical SAE 10W-40 viscosity grade and critical tolerances.:

• ACEA E4: The standard for diesel engines with extended oil change intervals operating in harsh conditions.
• API CI-4: For engines with EGR system and high loads.
• OEM approvals: A complete match (MB 228.5, MAN M3277, Volvo VDS-3, etc.).

Conclusion: The formal tolerances and applications of the oil are identical. Replacing one with the other will not cause any problems.

2. Base Number (TBN)

• UHPD: 15.3
• RINNOL: 15.6

Comment: Both values are exceptionally high. TBN indicates the oil’s ability to neutralize acids and operate at ultra-long service intervals (for example, up to 100,000 km for some manufacturers). The oils are completely similar in this parameter.

3. Detergent-dispersant Package (Ca)

• UHPD: Ca = 0.42%
• RINNOL: Ca = 0.502%

Comment: RINNOL oil has higher detergent properties. Calcium (Ca) is the basis of detergent additives that prevent the formation of deposits and keep soot suspended. The higher Ca content in RINNOL indicates potentially better protection from sludge and the ability to work in extreme conditions.

4. Anti-wear package (Zn and P)

• UHPD: Zn = 0.12%, P = 0.11%
• RINNOL: Zn = 0.071%, P = 0.065%

Comment: The key difference. UHPD contains the classic powerful ZDDP package (high zinc and phosphorus content). RINNOL uses a modern approach: the reduction in the amount of ZDDP is compensated by other advanced additives (for example, molybdenum or boron derivatives) that are not shown in the standard elemental analysis. This is done for:

• Improved compatibility with exhaust aftertreatment systems.
• Reduce friction and increase fuel efficiency.
• To provide similar wear protection using more technological methods.

Summary table of the analysis

Parameter	UHPD 10W-40	RINNOL OLGER PREMIUM 10W-40	Conclusion
Tolerances	It’s a complete coincidence	It’s a complete coincidence	Full analogues
TBN (alkalinity)	15.3	15.6	Full analogues
Washing Capacity (Ca)	0.42%	0.502%	Advantage of RINNOL
Anti-wear package	Classic (High ZDDP)	Modern (comprehensive)	Different approach, similar result in protection
Quality class	UHPD	UHPD	Both oils are top grade

Final conclusion and recommendation

The oils are complete analogues in terms of tolerances and are interchangeable.

1. UHPD (with high ZDDP): A proven solution for harsh environments, where maximum wear protection is traditionally valued.
2. RINNOL OLGER PREMIUM: A more modern oil with enhanced detergent potential and an advanced additive package. Its composition is focused on ultra-long replacement intervals, reduced friction, and performance in modern engines.

Recommendation:

• Both oils are suitable for engines Daimler (MB 228.5), Volvo, MAN and others requiring ACEA E4.
• The choice depends on your preferences: if you need a classic formula, UHPD, if you need a more modern and extended drain—oriented formula, RINNOL.
• For equipment with particulate filters (DPF), RINNOL may be preferable due to the potentially lower sulphate ash content (although both oils comply with E4, which allows operation with DPF).

Important: Both products belong to the premium segment and provide excellent protection.
