Hi there! Regarding your question about the ST2046 engine, here are the official oil specifications you'll need:
Service Class (API): You should look for oil rated SF, SG, SH, SJ or higher. These ratings ensure the detergent and anti-wear additives are sufficient for this engine.
Viscosity (SAE):
10W-30 is the standard recommendation for most operating conditions.
5W-30 is a great alternative if you’re working in colder climates, as it helps with easier startups.
Oil Capacity: The system takes approximately 1.9 Liters (or 2.0 Quarts).
