Every since my mom bought that car in 1991 she's used Premium gas. Mostly BP/Amoco fuels. But now they have added something called invigorate. And it's supposed to help you get better gas mileage. But now it seems that like my car's performance is slipping. I mean I dunno. Maybe it's the gas but I was trying to go and my legend seemed more sluggish than normal. Any suggestions?
