Just filled up the tank with 91 octane premium fuel

[darkmoon87]

Just to feel if there is any difference. (out of curiousity)

I didnt notice any power gain or anything like that, but one thing was quite noticable.


After installing my NST crank and waterpump pullies, the car became more sensitive to clutch and I had a little difficulty starting smoothly from 1st gear.
The car would shake more when I give the gas only as much as I used to give prior to the pulley install, so I had to be extra conscious with my clutch manuvering.

After filling the car up with 91, I can start from 1st gear with a relative ease. It starts noticably more smoothly.

Do u think this is just a placebo thing? Discuss.
