BP Premium Gas Invigorate problems.
I filled up with BP Premium 93 octane gas with Invigorate. Almost immediately after, engine started knocking then went away later that day. Next day I got a check engine light with code P0420 System Too Lean (Bank 1). Cleared it. Code has not returned. Well, BP wants clean burning gas and they've made it...good'n lean burning, but I will not buy it anymore. BP Ultimate never used to cause this. Shell, here I come.
