The SAE 5W-30 is a 4-stroke multi-grade oil. “5W″ indicates the viscosity of the oil at low temperatures and the number 30 indicates the viscosity at 100°C: this means that SAE 5W-30 guarantees high performance between -20° and +40°. The bottle contains 1.4 litres of product. This oil has been specifically designed for engines in STIGA machines and its use is recommended in order to obtain better performance and increase reliability and the duration of the engine over time.
The 4-stroke oil above all prevents the metallic surfaces of the engine from being worn down, creating a film which separates them. Moreover, it disperses heat and reduces wear and tear, acting as protection for the engine. A good oil prevents the accumulation of dirt and deposits, protecting the metal sides, combats oxidation and minimises the acids that may cause corrosion.
