Hello,

I’ve been using Shell V power lately. I used to gas up at this local chain where members get a cheque annually (like $50) but I noticed my car runs rough and pings a bit. Even for 91 octane. After switching to Shell V power it’s runs and idles really smooth. So if you have a petrol powered car I recommend.


Please help.

I didn't find the right solution from the Internet.
