Can you add 97 # oil to Chery A5 15 engine?

Your car manufacturer's fuel label is 93, so your choice is correct. I don't know how many kilometers you've driven. Generally, it's because the throttle valve, idle speed stabilizing valve and fuel injector are blocked by carbon deposits, which leads to unstable idle speed jitter. We should go to the service station for normal cleaning, restore the matching of factory computer settings and restore the original performance of the engine.

I hope the above answers are helpful to you, thank you!
