SHELL optimax VS BP ultimate FUEL ! For DOHC VTEC

[kindra]

I use vortex at caltex. I personally think its better. One day, I used BP and it fuked up my car. Had to get a new fuel pump and with Shell.. It was just crap. So, I either use Mobile or Caltex. Vortex the petrol got me heaps of K's and the boost it had was pretty good.

I don't understand why people are saying that they feel a 'boost'.. I never felt a difference in any of my cars when it was regular unleaded or Super Unleaded.

Heaps of my mates also say that they feel a boost with Super Unleaded.. Could it be just your brain 'thinking' that it's faster ?

Which unleaded 91 did you use, cause when I use BP unleaded 91 in my 121 bubble automatic with a/c on it feels less laggy than if I use Caltex unleaded 91.

Does that make sense, If you can tell me what you used? I'll avoid it so it wont make my car anymore laggier.

shell George. in my bike and gfs car - putting shell in makes it feel weaker and shit. Like those privately owned petrol stations fuel.
Anything else seems the same.
