Hi, seems to be a balance of what you are prepared to pay on a day to day basis and what you want to do with your car. What's the point of paying extra money for petrol if you can't realise the potential. For everyday driving to and from work in town driving the extra money that you pay for higher octane petrol is simply a waste of money if there is no discernable difference in mpg (I know that there is supposed to be an improvement, however is that improvement enough to justify the extra that you pay for it) however different people have different purposes for their cars.

It is interesting to read a previous comment that a chipped car will under perform with lower octane fuel - I'm sure that there will be lots of opinions on this - it is an interesting point. Most people use their cars for a multitude of purposes - how much of their cars potential do they use? To some people there is a balance of cost-effectiveness and performance.

It makes sense that if you chip your car the programming is optimised for higher octane fuel and if you drive in a manner that you feel justifies using higher octane (and feel that your engine will benefit from it)fair enough - however does it mean that if you are using the car for general purpose work that the car will underperform when you use choose to use standard 95 lower ron - in other words is it a compromise that will affect the choice of fuel that you use in that you feel that you must use higher ron fuel with the obvious implications of paying that extra for fear of under performance?
Being involved in the performance section I do see the benefit of chipping and upgrading, however I do see chipping as being a complex subject that needs to be addressed according to individuals' needs!
In the end we have indeed got the freedom of choice to use whatever mediums we feel will improve our cars performance and practicality - it would be good to have both!
