RINNOL OLGER PREMIUM 15W40

TBN = 10.9
%SA= we have the parameter %SOOT = 0.05
%w Ca= 0.415
%w P= 0.0731
%w Zn= 0.0792

we also have:
% Mg = 0.0009
% molibden = 0.0031
% Boron = 0.0273

Calcium is used as detergent neutralizing additives.
Phosphorus is a part of anti-wear and extreme pressure additives.
Zinc is an element of the anti-wear additive ZDDP.
Magnesium performs washing, neutralizing and dispersing functions.
Molybdenum (molybdenum disulfide) is added to improve protective, antifriction and extreme pressure properties. 

In most cases, a boron—based additive has a positive effect on engine operation – it reduces friction, improves engine elasticity, and increases the life of rubbing surfaces.

The short verdict: Both oils are full-fledged analogues of the highest level (SHPD – Super High Performance Diesel) for heavy diesel vehicles. They are completely interchangeable for use in engines requiring compliance with specified specifications (ACEA E7, API CI-4, etc.). The difference in chemical composition is due to different additive packages, but both provide excellent protection.

Detailed comparative analysis

1. Basic specifications and tolerances

It’s a complete coincidence: Both products have an identical SAE 10W-40 viscosity grade and a critical set of tolerances for modern commercial machinery.:

• ACEA E7: The key standard for heavy-duty diesel engines with extended replacement intervals.
• API CI-4: The highest standard for diesel engines of its time, implies operation under high loads and the presence of an EGR system.
• OEM approvals: There is complete agreement on the key manufacturers (Volvo VDS-3, Mack EO-N, MB 228.3, Caterpillar ECF-2, etc.).

Conclusion: The formal tolerances and applications of the oil are identical. Replacing one with the other will not cause compatibility or warranty issues.

2. Base Number (TBN)

• SHPD: 11.0
• RINNOL: 11.3

Comment: The values are almost identical and are at a very high level. TBN indicates the reserve of the oil’s detergent-neutralizing ability to combat acids from the combustion of sulfur fuels and to operate on extended drain (extended service intervals). Both oils are ideal for long-term operation in harsh conditions.

3. Anti-wear package (Zn and P)

• SHPD: Zn = 0.12%, P = 0.11%
• RINNOL: Zn = 0.087%, P = 0.074%

Comment: There is a key visible difference here. The first oil (SHPD) contains a higher concentration of the classic anti-wear additive ZDDP (zinc dialkyldithiophosphate). It is a proven solution for protecting friction pairs under high load.

A lower ZDDP content in RINNOL oil does not mean worse properties. Manufacturers often reduce the amount of ZDDP for several reasons:

• Compatibility with catalysts: A lower amount of phosphorus (P) is more favorable for exhaust aftertreatment systems (although this has already been taken into account for the CI-4 standard).
• The use of modern additives: The difference in efficiency is offset by more modern and expensive ash-free or other anti-wear components that are not shown in the standard elemental analysis (for example, molybdenum derivatives). The higher calcium (Ca) content in RINNOL also partially compensates for this.

Conclusion: Both packages provide excellent wear protection, but they use different approaches. SHPD is a classic “shock” ZDDP, RINNOL is probably a more balanced and modern complex.

4. Detergent-dispersant Package (Ca)

• SHPD: Ca = 0.36%
• RINNOL: Ca = 0.438%

Comment: Judging by the analysis, RINNOL oil has higher detergent and dispersant properties. Calcium (Ca) is the base of the detergent additive, which prevents oxidation products and soot from sticking together and forming deposits, keeping them in the oil volume. A higher Ca content indicates a potentially higher ability of the oil to “tolerate” harsh conditions and long replacement intervals without sludge formation.

Final conclusion and recommendation

Both oils are high-quality SHPD grade products and are 100% interchangeable.

SHPD: A proven solution with a powerful ZDDP package. An excellent choice for engines where this type of protection is traditionally appreciated (for example, for some modifications of older engines).

RINNOL FORMULA CLASSIC: Oil with a more modern formulation. The higher detergent additive content and probably a more balanced anti-wear additive package make it an excellent choice for maximizing replacement intervals and protecting modern high-load diesel engines.

Recommendation: You can safely use any of these oils in your technique, focusing on price and availability. Both will provide reliable protection.
