10% Ethanol - Good Info

Post by sirwilliam »

In the DC area we have 10% ethanol at many stations:


Is E10 (10% Ethanol) Fuel Safe in My Car?
Friday, 23 September 2005

Presenter: Spencer Howson

On March 1, 2004, the Federal Chamber of Automotive Industries released a list of cars which may safely use E10 ethanol-blended petrol. Ethanol is again in the news, so it seems timely to re-publish the list. Note, this is as of March 1, 2004, and more recent cars are not included. Any revised opinions by manufacturers are also not reflected.

Here's what the Federal Chamber of Automotive Industries published on its website on March 1, 2004:

Most new and many older vehicle models can run on E10 blended petrol. Vehicle manufacturers and importers have provided the following information on the capability of their vehicles to operate on ethanol fuel blends up to a maximum of 10% or E10 subject to the fuel meeting the octane requirements of the vehicle, complying with relevant mandatory Australian fuel quality standards and the AIP/FCAI Code of Practice for volatility characteristics (Fuel Volatility Index). The Commonwealth Government has limited the level of ethanol in petrol in Australia at a maximum of 10%. The information below provides technical reasons why some models cannot or should not use E10.

Before use of E10 in motor vehicles not listed below, you should consult your handbook or manufacturer to check if the fuel is suitable.


CARS:

Holden All petrol engine vehicles since 1986 will operate satisfactorily on E10 except as listed below. The following models which do not operate satisfactorily on E10 fuel: Apollo (1/87-7/89), Nova (2/89-7/94), Barina (1985-1994), Drover (1985-1987), Scurry (1985-1986), Astra (1984-1989).

Ford All petrol engine vehicles since 1986 will operate satisfactorily on E10 except as listed below. The following models may not operate satisfactorily on E10 fuel because of drivability concerns: Focus (All), F-series (1986-1992), Ka (All), Maverick (1988-1993), Mondeo (All), Transit (1996 onwards). The following models do not operate satisfactorily on E10 fuel: Capri (1989-1994), Courier (All), Econovan (pre-2002), Festiva (1991-1999), Laser 1.3L & 1.5L (1980-1989), Laser 1.6L (1989-2002), Raider (All), Telstar (All).

Mitsubishi All petrol engine vehicles since 1986 will operate satisfactorily on E10. Mitsubishi vehicles with carburettor fuel systems built before 1991 may experience hot fuel handling concerns and may experience a lower level of durability in some fuel system components.

Toyota All Toyota models manufactured locally or imported by Toyota Australia since 1987 will operate satisfactorily on E10 fuel except as listed below. The following models will not operate satisfactorily on E10 fuel due to material compatibility issues: Camry with carburettor engines pre July 1989 and Corolla pre July 1994.

MOTOR CYCLES:

Before use of E10 in motorcycles not listed below, you should consult your handbook or manufacturer to check if the fuel is suitable.

BMW All motorcycles since 1986 will operate satisfactorily on E10.

Harley Davidson All motorcycles since 1986 will operate satisfactorily on E10.

Honda All motorcycles and all terrain vehicles may operate satisfactorily on E10 but Honda does notrecommend it because there may be drivability issues. Drivability, performance or durability issues resulting from the use of E10 will NOT be covered by warranty.

Suzuki All motorcycles and all terrain vehicles do not operate satisfactorily on E10 fuel.

Yamaha All motorcycles and all terrain vehicles do not operate satisfactorily on E10 fuel.


TECHNICAL REASONS FOR INABILITY TO USE E10:

The following are reasons why certain vehicle models cannot or should not use E10 because of material incompatibility and driveability issues respectively. There are also comments on possible exhaust and evaporative emissions issues. This list was compiled from information submitted by manufacturers.

CANNOT USE BECAUSE OF MATERIAL INCOMPATIBILITY ISSUES

Early deterioration of components in fuel injection system:

Fuel tanks
Fuel lines/hoses
Injector seals
Delivery pipes
Fuel pump and regulator
Vehicles with carburettor fuel systems may experience hot fuel handling concerns and may experience a lower level of durability in some fuel system components.

Some manufacturers advise not to use E10 with any model equipped with a carburettor because of material incompatibility.

SHOULD NOT USE BECAUSE OF DRIVEABILITY ISSUES

Vapour pressure of fuel with ethanol will be greater (if not chemically adjusted) and probability of vapour lock or hot restartability problems will be increased.

Oxygen content of ethanol is 34.7%. This can cause the engine to run lean although the Engine Control Unit (ECU) can generally compensate via feedback from the O2 sensor under light throttle conditions. However, hesitation or flat-spots during acceleration can occur due to this lean-out effect.

Difficulty in starting and engine hesitation after cold start.

EXHAUST AND EVAPORATIVE EMISSION LEVELS

Lean-out resulting from the oxygenating effect of ethanol in the fuel may affect exhaust emissions.

Fuel containing ethanol can increase permeation emissions from fuel system components.

Vapour pressure of fuel with ethanol will be greater (if not chemically adjusted at the refining stage) and can lead to increased evaporative emissions.

so USDM STi's should be OK, right? they were manufactured after 2000.

Good choice putting $4,000 rims on your 1990 Honda Civic. That's like Betty White going out and getting her tits done.

Higher compression ratios for them.
