BP Ultimate vs Caltex Vortex

[theeone]

Once again, not a T but a 200kw "Whinger", 30 to 40 k's better per tank with Optimax, cant say I notice a distinct difference in power, but I think my Windsor's schitzo, one day if feels Blown the next if feels blown up!

If your going to up the boost, u must use the higher octane fuel. Otherwise pre-ignition aka knocking will occur... and engine life expectancy will go the wrong way.

Generally speaking the higher the octane, the higher chance of getting a 'cleaner' burn. Thus the chance the engine will produce its peak power output at every given rpm.

Having done quite a number of k's in my T, I can honestly say on the open road, the difference between ulimate and vortex (plus optimax/etc) is didly squat. U'll drink around 10litres. Power difference... well regardless which jungle juice u get, u will overtake cars like a low flying jet.

Where its going to make the biggest potential difference in the T (and most cars), is that 0 -> takeoff.

I dont get how there is an apparant performance diffrerence between optimax and ultimate, they are both 98 ron fuel. I cant tell the difference.

They are the same in RON rating. However, optimax is supposidly a 'denser' fuel then ulimate. ie the theory being that you will use less of it to deliver the same amount of power.

I didn't notice any diff with standard power, but once you upgrade its important to run 98, unless you have it tuned for 95 or whatever, like our NQ brothers.

With regards to fuel economy, there is no difference for me. However with the Shell Optimax you sure feel the difference, car handles better. My T loves the stuff.

Last load of fuel from Vermont in Vic seems to me to be the best batch of fuel I've used. My T purrrrrrs, squeeze the right foot, turbo kicks in and she growls

Gotta keep her sweet.

LOL

I love it how the car handles better with better fuel.

I used Vortex once and didn't think much of it.

I use Optimax mainly as the servo is on the way to work but I prefer Mobil Synergy over all the others as the car feels better. It might be all in the mind though!

I also like BP Ultimate as well

It mustnt slop around in the tank as much as the other stuff, therefore throwing the cars back end out around corners.
