I've i alwasy been filling up with 91 shell gas. And the other day i had to fill up with some cheap gas (valero) today .the car started acting weird it's (6spd) every time i pull up to a stop it feels like it wants to shut off the rpms drop to about 500 & i felt i slight vibration now. I checked to the trip computer and my mpg came down to 11mpg ,used to be at 19.. So if anyone can help please???

Bad Gas=water in gas..put in a bottle of Chevron techron and fill your tank with 93 ron if you can find it.Go to Sunoco.Run the tank of 93+Techron should be back to normal.Stay away from off brand gasoline.

Actually Valero is a top tier rated gas station. I have a few of them close to me and typically fill up at them now for years without an issue. That doesn't however mean that they could have had an issue at your particular station
