What fuel do you use?

Last week I filled up with Tesco Momentum. Spent the weekend cruising around Norfolk and Lincolnshire.
Before heading home I filled up again, but could only find bog-standard unleaded.
Within 5 miles of filling up the wife asked why the car wasn't popping so loudly on the over-run!
This is a perfectly standard 20iS, nothing modified in any way.

I saw no noticeable changes in consumption, performance or running smoothness, but yes, the pops are definitely less noticeable with the standard 95 fuel.

Not a very scientific test, as there was still a gallon or so of Momentum in the tank when I refilled, and likewise, beforehand when I put the Momentum in.

I appreciate it would require much longer exposure to each fuel in turn to be able to glean any useful facts but I can safely say, for my car at least, the Momentum is more 'poppy'.

So I get more Pop for my Buck :)

I always us ethe 'marginal gain' argument when this comes up.
i.e. if you're looking for a few extra 10ths at the Ring then maybe 98/super is the way to go.
Otherwise, save your pennies.

A relevant anaelogy; I always laugh at the cyclists here in Holland with the expensive carbon wheels on their €4k+ Pinarello Dogma bikes. They always blast away from me at the lights/bridge/whatever, but I always end up passing them 10km further up the road. Go figure.

If cyclists are beating you off the lights and it takes you 10km to catch up and pass them I would suggest there's something seriously wrong with your car! :rofl:

I was reminded of this thread the other day when I topped up my daily on a Tesco forecourt and noticed that both their Regular and Momentum are labelled as E5.
