E10 petrol

[milu]

Been covered before I think but now in the news for a September launch.
I try to use the non E5 esso super if I can and regular super otherwise.
I can see road trips being tricky though if you can’t get the juice needed.
Also not impressed with the premium charged by some garages for super. Bit of a rip off sometimes

All part of the game I guess

On the plus side you should get more MPG out of the E0 Esso 99 octane stuff (Esso Synergy Supreme +) than regular E5 95 octane, so that will pay for the price hike a little, but not all of it. More power too, which is of relevance to our cars too really.

The cost is however largely irrelevant in the grand scale of the cost of running an Aston really though unless you are doing like 20k miles a year in it, so maybe best just to look at the positive side of more power

Using either will be fine in all Gaydon era onwards cars, I believe the V12 DB7 is the last car produced incapable of using the new E10 when it comes out.

I will stick with E5 Super as the extra mpg I get from it over standard unleaded goes towards the price difference anyway.

I will get concerned though when we get the E15 seen in the US and other countries. Maybe the way the powers that be will force the old fossil fuel burners off the road and all into milk floats.

E5-E15 + ; Effingoil is highly corrosive, will eat metal , alloy , rubber, plastic , brass. etc.Governments trying to get old cars off the roads.

The odd tank full in an emergency won’t do any harm, it takes long term use to cause damage .

This is the advice on the gov.uk website.

I suspect storing the car with a tank full of E10 over a winter or two will be the worst crime.

Luckily I drive mine throughout the year.

Are you suggesting that the E10 fuel will get more corrosive as the fuel gets older - i.e. left unused in your car for some weeks/months?

Not really - I read somewhere that it can degenerate quicker over time if left unused.

The car or the fuel? Surely the car has fuel in it all the time in contact with the various components, so the main variable by the amount of use the car gets is the age of the fuel itself.

In fact, just thinking about it - what if using the car all the time meant that there was increased contact from fresh fuel, that hadn't already had its corrosive effect thus increasing the corrosion?

I really don't know the answer here - just questioning the logic behind the assumption either way.

Cars traditionally had steel fuel tanks and fuel pipes.

Do more recent vehicles (E10 acceptable) have alloy or plastic fuel tanks and pipes, to eliminate the risk of rusting?

The fuel, I think, quote from BBC News:

There have also been reports E10 is a less stable fuel, the RAC says, And this could make it more difficult to start a car that has not been driven for quite a while.

One of the controversies about Ethanol in petrol is its ability to absorb water, which is not good to have in your fuel system. As usual, there are arguments on the internet about whether it does or it doesn't, so I guess we have to make our own minds up.

The etanol absorbs water (condensation) over time, just like brake fluid, and when it has, if not used it will separate from the petrol so you will get a layer of water loaded ethanol in the bottom of the fuel system with the petrol on top (floating). This margin can then cause problems both through water corrosion (rust) and concentrated areas of ethanol that will damage plastics, seals etc not designed for long term exposure to it.

So, before you put your car into hibernation for any length of time, use all the fuel in it and then stick some E0 preferably, or E5 in it.

As a side note, ethanol produces less power than petrol, so the more E in it, the less the calorific value, and therefore power you will get. This then extends to an increase in fuel consumption, as if anyone with a V8 or V12 really cares?
