Optimax

[CRAPLOGINNAME]

Is there a boffin out there who can explain why I'm getting more mpg out of optimax then normal unleaded?

I'm mystified!!

Thanks in advance

I've also done a little anorak type calculation - based on 78p per litre vs 83p per litre (normal v optimax) I get 11.6p per mile Optimax v 11.8p per mile normal....just needed the figures to justify to 'er indoors why I'm buying expensive juice...'look luv, it's cheaper in the long run'
