Finally got BP Ultimate out here in the sticks recently, so filled up with stuff last weekend - can't really say I've noticed much when it comes to performance

BUT

even though I still have the original backbox, I can tell that the sound is different, a little lower than usual, and definately more appealing. Has anyone else noticed this?

 

Can't say I've noticed that with mine. But then the music's usually too loud to hear anything else...

What MY? And what fuel were you using before?

 

It's an MY00.

I only stopped at the BP garage as the optimax I had in wasn't going to get me to another shell station.
