Oil for Volvo 850 2.5 20V LPT (193 Ps Turbo)

Hello I’m Michael and new here. We bought a Volvo 850 BJ:1996 2.5 liter 20V LPT (193 Ps without all-wheel but with turbo) 320,000 km. The car only has an English manual because it was originally from Canada. I wanted to buy oil now, but I don’t know what oil I should take The old owner probably used cheap no-name 5w/40 because the car also consumed a lot of oil by high kilometers. Now my questions: In the operating manual under Oil Quality stands Meeting API specification SG, SG/CD,SH or Energy converting (EC) II and below SAE 5W/40 from -22 to 40°C. Now I found oil here and here, but the API doesn’t agree. Can I buy the oil anyway? What else would you recommend? Thank you for your help.
