I'd be surprised if anything changed in 1998. If it became law in 1998, manufacturers would have known years in advance and switched earlier so they weren't left with stock they couldn't sell.

I thought the same many, many years ago when I modified my old escort rally car fuel tank to move the fuel outlet away from just behind the rear wheel. Half an hour flushing through with water, then welded a plate over the exit hole. Near the end, I accidentally blew a hole and there was a quick high pitched pop and I heard a rustle in the nearby hedge. When I'd finished, I realised the filler cap was missing - I found it under the hedge where I'd heard the rustle. I then went to refit the tank and found it was now too big to fit back where it had been, especially the flat sides which were now curved outwards like a ballon.

I've never seen a 17p price difference before when I've looked. I don't normally buy it so I can't say exactly.

Seems the petrol companies are profiteering for the 'just in case' mentality. £1-50 for V-power today in my local Shell. Normal unleaded was £1-33 Thieves.

And if they do, run away.

I've heard good reports of Japex near Watford. I seem to remember someone from here tried them a few weeks back and was pleased.

I'd hazzard a guess that coping with E10 was made a legal requirement in Europe in 98, therefore a blanket statement.

Not sure how up to date this is, it has no indication of when it was posted. http://www.ethanil.co.uk/league-table/ Past rumours lead me to believe that tesco 99 gets it's increase in RON from using more Ethanol compared to Vpower, therefore Vpower produces more power and gives better economy (for the reasons above). Since it isn't in the league table above, maybe it does indeed use the maximum 5% currently allowed.

Stoich afr of Ethanol is 9, petrol is 14.7. For mixtures, it's a linear scale. By my sums that makes 14.1 for E10 so about 4% more fuel needed. Closed loop systems will compensate and will lose ecconomy. Open loop systems will run slightly weaker. Since open loop tend to run rich, this is possibly a benefit. The danger is open loop with aftermarket mapping with safety margin removed.

If 5% ethanol doesn't rot fuel lines, why should 10%. IMO the biggest danger is to GT4 owners with aftermarket ecus with less safety margin. Ethanol will run weaker on an open loop map. Ethanol has a higher RON which should reduce detonation, however I suspect they will just reduce the other octane boosters so no overall increase.

Another one from the Swiss trip in 2009 (there were as many in front too).
