It should be fine. If in doubt, buy 97/98 RON fuel as it has less ethanol.

Whatever you do, don't leave it parked up with a tankful of E10.

Basically it breaks down over time, so as long as you're buying fresh fuel and using it, you shouldn't have any issues.

The direct injection 2.2* in the Vectra C might be less forgiving.

Completely different engine and best avoided.

It does say on the gov.uk that Vauxhall’s with direct injection won’t run it
Wasn’t sure if omega 2.2 was direct injection

Totally different engine :y The Omega would probably run on Polish Vodka :D

The issue with that engine is a membrane in the high pressure pump... it had issues from new with low grade fuel, basically it requires Premium unleaded. Throw in a bucket of ethanol and it would have a proper meltdown ;D

Incidentally, Ethanol based fuel isn't a new concept. South American fuel has been ethanol based for decades. It's just that our cars generally weren't always built for anything other than plain un/leaded petrol or diesel.

Also, in much the same way as you can get additives for old cars to run on unleaded, there are stabilisers for Ethanol fuels.

Fat fingers...!! ::) ::)

According to the Esso website, their Synergy + 99 Super Unleaded has no ethanol content, except in a few locations such as Devon and Cornwall, North Wales, North England and Scotland. Although legally, the pumps have to display the E5 sticker, even if the fuel is 0% ethanol content as with their Synergy +99 super unleaded.

Although one Esso station near me are selling the 99 'good stuff' and charging 146.9p per litre for it...
I can see the Super Unleaded going through the roof like proper Leaded fuel (not the Lead Replacement Petrol - LRP) after it was phased out in 2000....

That'll be an issue driving more interesting cars, as they generally demand Premium as their fuel of choice :-\

I did resist buying 82 litres of Premium this morning... £1.35 a litre was enough :D
