Announcement from Honda : Ethanol

[ahcash]

Just logged in to the Honda owner's website and discovered this. For those who haven't already known..Some loss of power and fuel economy may occur




Ethanol
The following Honda vehicles may be operated using fuel containing up to 10% ethanol (E10):

Accord
2003 onwards

Accord Euro
2003 onwards

Civic (including Hybrid)
2004 onwards

CR-V
2003 onwards

Jazz
2003 onwards

MDX
2003 onwards

S2000
2004 onwards


Other Honda vehicles were not designed or tested with E10 and therefore the long-term effects are not proven.

Ethanol contains less energy value than petrol. In theory, some loss of power and fuel economy (possibly 2-3%) may occur when using E10.

For further information, please refer to your vehicle owner's manual, or telephone the Honda Customer Hotline on (freecall) 1800 804 954.

I'll stick to 98RON thanks very much.

[crazyray]

i agree with that

98RON all da way ;D

[channeldavid]

Sorry, i am not rich!
If i have money and/or feeling happy to spend money -> 98
If i have no money and/or feeling sad/angry -> Regular

[Half Schumacher]

but given the fact that i travel around 8000km per year, the total amt i paid isn't that much more.

[nick]

well, now I always use 95~ unless the price goes up to 130~~ but not a problem to me at the moment~ maybe I haven't tried to full load my car while goin up the hill~~ still powerful to me at the moment

[channeldavid]

philip, for u is good, coz' your office is near your house. but i need to travel from sothside to City everyday!

From what I understand, even premium unleaded petrol (RON 95) might contain E10... but, they will be clearly stated at the station...

E10 (a generic name for a blend of 10% ethanol in either regular or premium unleaded petrol) is sold under various Caltex brands – Caltex, Ampol and Bogas – at about 40 sites in North Queensland and country NSW. All pumps selling E10 are clearly labelled. E10 is also being trialled by some commercial customers in North Queensland. Caltex has ethanol storage and blending facilities at its terminals in Cairns and Newcastle. E10 typically results in poorer fuel economy than straight petrol, as a litre of pure ethanol contains about 33% less energy than a litre of petrol. The effect on individual vehicles will depend on the particular vehicle, including its engine technology. Individual vehicles vary widely but 2 to 3% poorer fuel economy is a reasonable typical estimate based on the published results of vehicle testing. Motorists would find it difficult to notice this difference in everyday driving.

The addition of ethanol to standard unleaded can increase Research Octane Number (RON) by up to 4 Research Octane Numbers but has a much smaller effect on Motor Octane Number (MON), typically up to 2 motor octane numbers. The effect on RON and MON depends on the particular petrol being blended and needs to be determined by analysis.

RON is the "octane" rating commonly advertised at the pump. All petrol that is properly formulated will have at least the specified RON and MON, regardless of ethanol content, and other regulated specifications. Regular unleaded petrol has minimum octane numbers of 91 (RON) and 81 (MON). Premium unleaded petrol has minimum octane numbers of 95 (RON) and 85 (MON).

Using petrol with an octane rating higher than specified by the manufacturer should not improve vehicle performance but will generate additional greenhouse gases in refining the petrol. All other things being equal, motorists should use petrol with the octane rating that is specified by the manufacturer as best for the particular engine. However, some higher octane petrols such as Caltex Vortex (95 RON) and Vortex 98 (98 RON) have additives that clean up the fuel system and can improve and maintain performance as a result. A vehicle’s requirement for octane may increase over time due to the build up of carbon deposits in the combustion chamber during the life of the vehicle.

Also, ( ;D HEHE!! I try not to turn this thread into another Petrol Talk .. )

Good info..

To be considered a premium unleaded fuel, RON must be a minimum of 95.0 and MON 85.0. The addition of 10% ethanol increases the RON by substantially more than it does the MON.

• Testing completed by Intertek for the Department of Environment and Heritage shows that:

– the addition of 10% ethanol to a 91 RON compliant fuel increased the RON to 95.6 (up 4 points) and the MON to 84.3 (up 2 points). The resulting MON meets the specification for unleaded petrol but not for premium unleaded petrol.

– The addition of 10% ethanol to a 95 RON fuel increases the RON to 98.5 (up 3.1 points) and the MON to 86.9 (up 1.3 points), which meets the requirements of premium unleaded petrol (because it started as premium unleaded petrol).

– Whilst Australian fuel standards do not set specifications for 98 RON premium unleaded petrol at this time, the World Wide Fuel Charter (an industry standard) suggests specifications for 98 RON fuel to contain a MON of 88. The addition of 10% ethanol to a 95 RON fuel does not meet the MON suggested by the World Wide Fuel Charter for a 98 RON fuel.
