Shell Optimax
 

Having allways used Shell Optimax petrol I watched Fifth Gear last night as they ran a test on various fuels - normal unleaded, BP ultimate, Shell Optimax etc. While it didn't have much effect on engines in a low state of tune, it did make a difference to high performance engines - an Imprezza got something like a 30 bhp gain.

I can feel the difference in my 749S if I use Optimax. Throttle response is better and the bike runs smoother.

My 748 R ran 108.2 BHP at the back wheel on Optimax.

So have you thrown down the gauntlet then Steve? The SS breathes fire now then?

I've re-named it Puff - skins will be coming of rice puddings like never before!

It's true, my old SP4S runs a helluva lot smoother with Ultimate or Optimax, quicker warming up and no coughing and hunting when cold.
Add a touch of octane booster too and wayhey!!! :burn:

The exhaust note is different too, not only do you get the deep rumble but also a sharp crack like a highly tuned two stroke note mixed in.
Sounds fanstastic. :D:D

Ains.

yep i used it on my hornet 600 to great effect smoother, just generally went better:):)

Now I dont work on the way to a shell garage is the only reason I dont get it now for the s4r:o:o

I saw the program too and I was surprised....I thought the Optimax thing was just marketing bollox, but....

The ST can keep drinking the normal stuff but I'll use Optimax in the 888 from now on

AK wont use anything else for any of his bikes.

I try to remember for mine:rolleye:

I run my (rather sporty!) car on Optimax 90+% of the time. According to the forum frequented by other owners, fuel consumption is about 10% better so it pays for itself anyway.
