World First - Racing-worthy specifications available to everyone.
Motor Milk™ 5W-30 A3/B4
A synthetic engine oil made from carefully selected raw materials, designed to provide maximum protection for modern gasoline, diesel, and racing engines.
The product is based on a PAO and ester-based base oil blend suitable for racing. The formulation contains a full SAPS (Sulfated Ash, Phosphorus, Sulfur) level, which improves lubrication, ensures excellent wear protection, and supports reliable operation even during cold starts.
Thanks to its high-quality PAO/ester base and high additive content, Motor Milk™ 5W-30 A3/B4 combines a modern viscosity grade with high-performance lubrication technology for demanding operating conditions.
Motor Milk™ 5W-30 SP/C3
A fully synthetic engine oil made from carefully selected raw materials and developed to provide maximum protection for modern gasoline, diesel, and racing engines.
The product is based on a pure PAO and ester-based base oil blend suitable for racing. The formulation includes a high-tech SAPS additive package and a racing-grade ZDDP package, which improves lubrication, ensures excellent wear protection, and optimizes cold starting properties.
C3 5W-30 is Motor Milk's more modern, more efficient, and more emission system-compatible option in this viscosity class.
Which one should I choose?
-
If your vehicle is used for track driving or is tuned, we primarily recommend Motor Milk's genuine 5W-30 A3/B4 version.
-
If you have a modern, standard (OEM) configuration vehicle and want to follow the manufacturer's recommended C3 classification, this 5W-30 SP/C3 offers modern viscosity and emission requirements, as well as the maximum ZDDP level allowed by that classification.
Thanks to this overall package, Motor Milk™ 5W-30 SP/C3 represents the most technically advanced 5W-30 SP/C3 engine oil worldwide.

Motor Milk™ 5W-30 ensures race-level performance with the following features:
-
Race-grade viscosity and excellent heat and oxidation resistance - Compare to others
-
Durability in demanding, high boost pressure conditions
-
Improved protection against sludge formation
-
Increased power*
Designed for demanding use.
Motor Milk's unique formula contains:
-
High SAPS content (Sulfated Ash, Phosphorus, Sulfur)
-
Abundant ZDDP additives (Zinc Dialkyldithiophosphate)
-
High ester base
What does this mean in practice?
- Exceptional thermal stability
- Extremely strong oil film under heavy load
- Better protection in turbocharged and tuned engines
- More effective cleaning – cleaner engine internals
Why isn't regular "premium" oil enough?
Current emission requirements and cost savings have weakened the composition of many oils on the market. Additives have been reduced, and protective properties trimmed.
Regular "premium" oil works for street driving, but not under demanding load.
High viscosity even above 100 degrees - Compare to others.
High viscosity ensures:
-
Stable oil pressure under heavy load
-
Reliable protection in the extreme temperatures of turbocharged engines
-
Strong lubrication film even at high RPMs
The abundant ester base improves lubrication and helps keep engine internals cleaner – even in harsh conditions.
Philosophy: No compromises
