How old though, are we talking pre unleaded era cars?
I was going to start a new topic, but found this one...
With the other post about premium vs standard fuel, I spotted a headline on my phone about E10 fuel.
Is this actually coming in now? Presumably it will be less efficient, so while producing less pollution/litre the car will in turn use more litres?
As long as they don't remove any 99ron pumps for this...
Widely used in Australia, noticed no difference between E10 and regular 95 economy wise.
Only a problem if you have an old car, similar to leaded and unleaded petrol.
E10 is cheaper than 95 by 1-2%.
And Canada and the US.
No idea on fuel economy though, other than E85 reduces it by about 20%, so 10-15% ethanol is going to have negligible difference.
The cars set up for anything up to E85 so there’s no mechanical reason why not for me.

MX-5's pre 2005 cant take it and a load of others, maybe a few quid to be made in aftermarket seal kits![]()

Isn't this the same stuff they've been using in France for years with no problem? If so then I've filled up with it many times and didn't notice any difference.
So what Ron would this be? As we know Momentum and shell use up to 5% to get their Ron rating.
