Has anyone else done this? I was headed home from work the other day and was not thinking when I stopped to fuel up. I absently-minded put 10 Gallons of 89 Octane in my girl and nearly cried when I realized it. /cry
I run Shell 93 exclusively and as often as I can from the same service station. There was another car in my "usual" pump and I took the next bay over... I grabbed the yellow handle to the far right, which is 93 on my usual pump, and noticed when hanging the pump up it as 89 Octane!!! Ughhh!!!
The car had a little less than a 1/4 tank when I stopped to get gass, so at least it was not empty and the mix should have been a little better than 89.. but wow, what a screw-up.
As for performance I did not notice anything for a while but as I drove this past week I could clearly feel the computer/sensor had dialed back the timing... it felt off, not poky mind you... but off. Even the exhaust sounded off to me.
Anyway, I've burned just about all of it out this week and will fill up tomorrow... making damn sure it's 93 Octane! :grin2:
