FW: [Syncro_T3_Australia] re: Ethanol E10

1
Phill,
Thanks for the clarification/distinction.

According to the VAG owners manual then, I see it merely states ULP 91 (minimum) for the Oz WBX 2.1 motor. So by implication, what then is VAG NOT telling owners?
For example, are any of the following points relevant if one chose instead to invest in ULP 95 or even ULP 98? ...

ECU can detect & adjust timing accordingly; engine simply operates more efficiently; runs cooler; runs cleaner; heads less stressed; achieves more kilometres on a tankfull; engine lasts longer; etc. etc.
Or are some/all of those in the urban myths category also?

Also, despite VAGs apparent seal of approval for E10 in fuel injected post 1986 engines, is there then actual contrary "real life, hands on" evidence that E10 is/has been deleterious to the Oz WBX 2.1 engine and/or its associated system components? TIA. Cheers.
Ken

You are comparing two different things here.

Ethanol has a lower BTU rating than petrol. That means that you must use more of it to get the same work done.

Octane is the knock ratiing. Higher octane will allow you to advance the ignition timing and increase the compression ratio to make the engine more efficient.

E10 causes corrosion problems as it hold water.

The message was that the chart is a load of garbage. (Nothing to do with MV engines)

I never run 91. That is third world fuel for third world countries.
91 is the minimum octane for MV engines. Our 91 fuel when tested is always less than 91 RON.
Australian T3s were having lots of problems with cracked heads and all of them were running 91 from what I was told.

The MV ECU does not know what fuel it is running. There are no knock sensors.

VAG has said that all post '86 VW engines can run on 10% ethanol. Not E10.
