Hey guys
I was going to start another thread, but came across this one and will put my experiences on here and see what you guys think...
I normally fill up with Shell V-Power as my preferred fuel, however the other day (4 days ago), the line to the station was absolutely massive, and after queuing up for about 25 mins, I finally got to the front, and the only bowser available to me was the 95 unleaded. There was no way I would be queuing up again to get to the only 1 Shell V-power bowser, so I put about three quarters of a tank in.
However today, as I was going through the gears, 1st to 2nd is fine, but from 2nd to 3rd, and 3rd to 4th, from about 3,000 to 4,300rpms, it feels as though my car is choking or dare I say it... constipated. That feeling that it wants to rev, but it can't.. You can feel it, when it gets higher, the car sounds restricted for some reason and you feel the car back off the throttle (even when my foot is down), I can't really type the feeling, but I'm sure you may know what I am talking about.
What do you guys think it is...? I have a feeling it may be the fuel changing in the engine and its just lost the octane of the other fuel... it's not going to cause me further problems down the track is it?
Am I even making sense?!

Please shed some light on this. thanks!
