Aygo And Petrol/e85

[Locket2]

Hi

Has anyone tried running the Aygo on a 50/50 mix of petrol and E85? This seems to be working fine in most cars, but i'm curious about if anyone has done this with an Aygo?

If yes; do you mix it with 95 or 98 octane?

Since the gas prize here in Sweden has reached $2.25/l (£1,14/l) i want to try to lower my fuel costs a bit (running on cut down rainforest is good for the enviroment, isn't it? :P )

Thanks for the feedback

Isn't that illegal???

In The Netherlands you're not allowed to run your Diesel on chipfat, even though it workes fine on older Diesels.

This is just for the simple fact that the government doesn't allow you to run on non-taxed fuels over here :(

In the UK It's legal to use chip fat in the diesel cars that can cope with it, you can even convert chip fat to bio-diesel yourself. If you use less than 2500 litres per year then you don't need to pay and duty on it. If you go over then you need to pay UK Customs/Excise duty (I assume on amount above 2500lt)

Well, if it's legal or not is not the thing in this case.

I just want to know how much E85 i can pour into my tank without the engine, hoses and gasketgs taking damage :)

£1.14 per litre - we shoud be so lucky . . . . .

- I have just filled 10 litres of E85. :) . That will be about 30 %. We will see what happens. :o :D

[edit] Comparisons to regular gasoline

Depending on composition and source, E85 has an octane rating of 100 - 105[4] compared to regular gasoline's typical rating of 87 - 93. This allows it to be used in higher compression engines which tend to produce more power per unit of displacement than their gasoline counterparts. Since the reciprocating mass of the engine increases in proportion to the displacement of the engine E85 has a higher potential efficiency for an engine of equal power.

One complication is that use of gasoline in an engine with a high enough compression ratio to use E85 efficiently would likely result in catastrophic failure due to engine detonation, as the octane rating of gasoline is not high enough to withstand the greater compression ratios in use in an engine specifically designed to run on E85. Use of E85 in an engine designed specifically for gasoline would result in a loss of the potential efficiency that it is possible to gain with this fuel. Using E85 in a gasoline engine has the drawback of achieving lower fuel economy as more fuel is needed per unit air (stoichiometric fuel ratio) to run the engine in comparison with gasoline. E85 also has a lower heating value (units of energy per unit mass) than gasoline leading to a reduction in power output in a gasoline engine.

E85 consumes more fuel in flex fuel type vehicles when the vehicle uses the same fuel/air mixture and compression for both E85 and gasoline because of its lower stoichiometric fuel ratio and lower heating value. European car maker Saab currently produces a flex fuel version of their 9-5 sedan which consumes the same amount of fuel whether running e85 or gasoline[5], though it is not available in the United States. So in order to save money at the pump with current flex fuel vehicles available in the United States the price of E85 must be much lower than gasoline. Currently E85 is about 5-10% less expensive in most areas.[6] More than 20 fueling stations across the Midwest are selling E85 25%-40% cheaper than gasoline.[7] E85 also gets less MPG, at least in flex fuel vehicles. In one test, a Chevy Tahoe flex-fuel vehicle averaged 18 MPG [u.S. gallons] for gasoline, and 13 MPG for E85, or 28% fewer MPG than gasoline. In that test, the cost of gas averaged $3.42, while the cost for E85 averaged $3.09, or 90% the cost of gasoline.[8][9] In another test, however, a fleet of Ford Tauruses averaged only about 6% fewer miles per gallon in the ethanol-based vehicles as compared to traditional, gas-powered Tauruses

From this i dont think its that good , I see too many times the words ' LOSS OF POWER ' and i dont like that :)

[aygo vvti]

dont think it will be good

[BadBoyVTEC]

where is that extract from?

[Locket2]

Actually i don't care about the loss of power. With the current gas price and slow moving traffic the power really doesn't matter, but the gas consumption does.

I still havnen't tried it, Strykollon, how did it work for you?

[BadBoyVTEC]

Its not the loss of power that is a problem its the fact that you will naturally adjust your driving to compensate for the loss therefore using more fuel.

[Strykollon]

I still havnen't tried it, Strykollon, how did it work for you?

- It has worked very well. I did notice veeery little loss of power, almost nothing. I came a little longer

on this tank due to a little more driving on the countryside.

No starting problems whatsoever.

The conclusion of this is that you can save about 5€ if you fill 10 litres E85 to each tank.

I wonder what Toyota says about the warranty if something happens to the engine?
