E10 mpg?

[tiglon]

E10 in a 35???

After 60k miles in my 35iS on good ole 95 RON, tried that highfalutin V-Power and had to have new injectors, coil packs & plugs. Happy to be on E10 now, running smooth as silk.

Could it perhaps be that you just needed new injectors, coil packs and plugs because you'd done 60k miles and nothing to do with the fuel?

In the world of debate about V-Power, nah. Far too logical. Mind you, it did happen when I tried it.

Or you could say that the cheap fuel had knackered the whole system in that time which otherwise would not have happened

V power has the habit of cleaning out crap. Might have moved something to block injector.

Ethanol has a lower calorific value than gasoline so your gallon is now in effect less effective so its impossible to achieve more mpg on a lower calorific fuel. Ethanol is however 'greener' so it lowers your emissions per gallon which is the governments aim.

So we should all be reporting a decline in mpg.

Yes, I thought that. However, the indy and the AD both came to the conclusion that the problem was caused by an upper engine oil leak and, under insured warranty, the AD fixed it.

You would expect so bud

That is what is reported as an expected side effect of using E10

In an engine, burning a less energy-dense fuel means that you need to burn more of it to get the same amount of power. This doesn’t mean that you’ll lose power if you use E10; rather that your fuel economy will drop as your car’s engine computer fiddles with fuel-air ratios to get the best stoichiometry (a fancy-pants term for the ideal mixture). So while the carbon count goes down with ethanol-blended petrol, fuel consumption goes up.

“And those with E10 compatible cars will unfortunately find they are getting fewer miles to the gallon as the fuel is less efficient than E5 fuel, due to it containing 5% more ethanol.

New E10 fuel could reduce a car's economy by 10 per cent

Wow, that’s shocking! I’d heard of a 3% drop in economy before but not as high as 10%, that’s an even better reason to run on super-unleaded

Thank you, pvr.

My car use is consistent and, since E10, the mpg's improved slightly, so perhaps the motoring journalists aren't infallible. But, hey, like all journalists, they're scum, anyway.

[Nanu]

This thread was asking the question does E10 fuel give you less MPG. From my experience the answer is no. I just wonder if part of the reason for the price rise is the extra Ethanol which is being masked by the general rise in oil prices worldwide.

Or even "dangerous" / "Criminal" reduction in fuel efficiency
