just tried e10 95 for the first time

[tunga]

Just put a tank of E10 95 0ctane through the senator seemed to be really good and almost 30cents a lt cheaper than equivilant bp premium 95 does anyone know of any downsides to this fuel ? cheers

I have tried this fuel however after logging about three tank fulls there was some timing being pulled due to knock so I have changed back to 98 RON.

In fairness to the E10 car was tuned for 98 RON.

We have 98RON E10 here in NZ but it's only marginally cheaper and the lower km per tank seems to make it about the same value as normal 98

I used E10 before i had the tune done and it used a lot more fuel compared to the regular 95 i was using at the time.

They do say you use 10% to 20% more.

I've been running this fuel in my daily turbo volvo wagon for around 40,000km. So far no issues, and around 25cents cheaper than 98ron petrol.
I believe is it made from CSR ethanol which is better than the stuff shell were using (now discontinued)

What about E85, would it have the same fuel economy as E10?
How hard would it be to convert a VY to run on it?

Have been running this in my Addy for over 12 months.

Was tuned for it and I can get around 9.8l/100 on the hwy and avg 12 around town.

From Wikipedia ===



In theory, all fuel-driven vehicles have a fuel economy (measured as miles per US gallon, or liters per 100 km) that is directly proportional to the fuel's energy content.
In reality, there are many other variables that come into play that affect the performance of a particular fuel in a particular engine.

Ethanol contains approx. 34% less energy per unit volume than gasoline, and therefore in theory, burning pure ethanol in a vehicle will result in a 34% reduction in miles per US gallon, given the same fuel economy, compared to burning pure gasoline.

Since ethanol has a higher octane rating, the engine can be made more efficient by raising its compression ratio.

For E10 (10% ethanol and 90% gasoline), the effect is small (~3%) when compared to conventional gasoline, and even smaller (1-2%) when compared to oxygenated and reformulated blends.

For E85 (85% ethanol), the effect becomes significant. E85 will produce lower mileage than gasoline, and will require more frequent refueling. Actual performance may vary depending on the vehicle. Based on EPA tests for all 2006 E85 models, the average fuel economy for E85 vehicles resulted 25.56% lower than unleaded gasoline.

Ethanol blends are also hydroscopic. That causes them to become mildly corrosive.

Hygroscopic ;)

And the ethanol itself causes problems with rubbers and plastics that aren't made to handle them - more a perishing than a corrosion, but the water that ethanol blends can absorb can be a problem too
