2013 Camry SE OCTANE
 

Well first of all this is my 2nd camry with basicallt the same engine,from the time I got them I was under the impression Via the OWNERS MANUAL,that I did not need to use any gas but regular unleaded,thru the last year of having my 13 SE,ive had my car at the dealer saying "This car Drives Like ****",poor acceleration,hard shifting,rough idle.ect..and I usually keep my tank full of Shell Regular unleaded,so I decided to run my tank low,and refill with 89 WOW all my problems and complaints GONE,car drives AMAZING midgrade is the way to go in these cars,never again will I use 87 it SUCKS

Weird, car should run just fine on 87. Do you always fill up at the same place? I wonder if that place got some crappy gas, it's not unheard off.
