Motor oil RENA Ultra 10W-40
Motor oil RENA Ultra 10W-40
High-quality 10W-40 semi-synthetic motor oil. Reduces engine wear and ensures clean parts thanks to a balanced additive package.
Operating in city start-stop mode contributes to premature wear of parts and sludge accumulation. RENA Ultra 10W-40 motor oil is designed to effectively protect engines under such conditions. The optimized kinematic viscosity (14.4 mm²/s at 100°C) guarantees stable system pressure. Thanks to the high base number (10.0 mg KOH/g), the oil neutralizes aggressive acids formed during fuel combustion. To discuss individual supply terms and calculate costs, please leave a request on the website.
The oil is formulated from highly refined base components with a balanced additive package. Compliance with API SN/CF and ACEA A3/B4 standards guarantees high resistance to thermal degradation and shear. Metal content is strictly controlled via spectroscopy (ASTM D6481).
