Comparative analysis of UHPD 5W-30 and RINNOL OLGER PREMIUM 5W-30 engine oils

The short verdict:
Both oils are high-quality fully synthetic (based on base oils of Group III/IV) UHPD (Ultra High Performance Diesel) products for modern diesel engines. They are analogs and can be used interchangeably for applications requiring compliance with specified specifications (especially ACEA E4, MB 228.5, Volvo VDS-3). However, there are significant differences in chemical composition between them, which indicate a slightly different approach to formulation.

Detailed parameter analysis

1. Basic specifications and tolerances

It’s a complete coincidence: Both products have identical SAE 5W-30 viscosity grade and key tolerances for heavy machinery.:

• ACEA E4: The most important standard for oils with extended replacement intervals operating under severe conditions compatible with diesel particulate filters (DPF).
• API CI-4: For high-load diesel engines with EGR system.
• Critical OEM Tolerances: Daimler MB 228.5, Volvo VDS-3, MAN M3277, Mack EO-N. The MB 228.5 tolerance is especially important, as it imposes some of the strictest requirements for evaporation, oxidative stability and wear protection.

Conclusion: The formal tolerances and applications of the oil are identical. Replacing one with the other will not cause compatibility or warranty issues if your engine requires, for example, MB 228.5.

2. Base Number (TBN)

• UHPD: 12.5
• RINNOL: 12.3

Comment: The values are almost identical and are at the high level required for long service intervals and acid neutralization. The oils are completely similar in this parameter.

3. Detergent-dispersant package (Ca, Mg)

• UHPD: Ca = 0.35%, Mg = 0.01%
• RINNOL: Ca = 0.254%, Mg = 0.0005%

Comment: A significant difference. Judging by the analysis, the detergent properties of UHPD oil are significantly higher. The combination of calcium and magnesium is a powerful detergent-dispersant complex that effectively combats deposits and retains soot. The lower content of these elements in RINNOL suggests that the manufacturer probably relied on other components or a type of dispersant not shown in the elementary analysis in order to meet the same tolerance requirements (especially for ash content for MB 228.5).

4. Anti-wear package (Zn and P)

• UHPD: Zn = 0.08%, P = 0.08%
• RINNOL: Zn = 0.064%, P = 0.06%

Comment: The concentration of the classic anti-wear additive ZDDP in UHPD oil is also higher. This indicates a more “conservative” and reliable approach to wear protection. The lower ZDDP content in RINNOL, as in previous cases, is compensated by modern ash-free or low-ash anti-wear additives (for example, based on molybdenum or boron), which are not visible in this analysis.

Summary table of the analysis

Parameter	UHPD 5W-30	RINNOL OLGER PREMIUM 5W-30	Conclusion
Tolerances (ACEA E4, MB 228.5, etc.)	It’s a complete coincidence	It’s a complete coincidence	Full analogues
TBN (alkalinity)	12.5	12.3	Full analogues
Washing capacity (Ca+Mg)	High (0.35% + 0.01%)	Moderate (0.254% + 0.0005%)	UHPD has an advantage
Anti-wear Package (ZDDP)	Higher concentration	Lower concentration	UHPD has an advantage
Base oil	Group III/IV (Synthetics)	Group III/IV (Synthetics)	Full analogues

Final conclusion and recommendation

Both oils are technologically advanced synthetic products of the highest class and meet the strictest tolerances (MB 228.5, VDS-3). They are interchangeable.

1. UHPD 5W-30: An oil with a more “powerful” and possibly more “conservative” formula. The high content of detergent and anti-wear additives (Ca, Mg, ZDDP) indicates its focus on maximum protection in the harshest conditions and on maximum safety margin throughout the extended drain interval.
2. RINNOL OLGER PREMIUM 5W-30: An oil with a more modern and probably more “elegant” formulation. The manufacturer has achieved compliance by using possibly more modern and expensive types of additives that are effective at lower concentrations. This is often done to optimize ash content parameters and compatibility with aftertreatment systems.

Recommendation:

• For new engines where low sulphate ash content (SAPS) is critically important and DPF compatibility, both oils are suitable, but the RINNOL formula can be more optimized for this.
• For conditions where extreme loads, increased soot formation, or low-quality fuel are expected, the UHPD formula with its more powerful detergent and anti-wear package can provide a slightly greater margin of reliability.

Overall, both options are an excellent choice for modern commercial vehicles.
