Okay, Awhile ago I stopped buying BP 89, because the car began to run worse, instead of better, and lost a couple of mpg as well? I have been only using BP 87 since. I get the best power, & mileage on this over other brands too. Well, my lady went to fill up yesterday, and accidently got BP 89 instead. Next, she called me on the cell to say she just got gas, BP 89, and the car was "chugging"? I said, "I told you not to use 89 anymore, just 87", she forgot. Because the 89 wasn't the same anymore there? Next, we both noticed the gas mileage went from 20mpg, to 18mpg!
"Chugging" is the term she uses to describe that the car seems to be working harder then normal,,, lol, but I've definitely noticed this effect myself.
