What differentiates PSA 0W30 oil from others?

The abbreviation “0W30” indicates the viscosity:

• “0W” = excellent fluidity at low temperatures (easy cold start);
• “30” = ideal resistance at high temperatures, protecting the hot motor.

But the secret lies in additive technology.
PSA B71 2312 oil contains specific compounds for emissions control, turbocharger protection (in turbo versions of other models) and compatibility with particulate filters (GPF/DPF).

Even in the naturally aspirated C3, this brings less waste generation and greater energy efficiency.
