lecoq,
I may be able to help you after all, but not the way you think. I think we MAY be able to get you more milage by improving what you have.
Tell me first what kind of driving you do? City and congestion or highway/country road driving?
Gas here in Texas is currently $ 2.80(UDS) a gallon for premium octane. With 3 litres to the gallon thats .93 a litre, in euro thats about 1.25 euro. Not much difference.
Get back to me with the answer to my questions and I may have a link that will help you out some.
Lad
