E 10 petrol

I did the same with the Jack, light came on running like a hairy goat, When back to using premium and problem resolved itself after a while.

The Mythe of Ethanol again, Team Vodafone V8 Supercars will be using E.85 next year, Craig Lowndes says the cars perform just as hard during trials at Willowbank. The option is open to any other team who wishes to use it.

I've used E10 on numerous occasions in my V8 Adventra with zero issues. Although I was overall happy with it, the small cost difference outweighs the distance I need to travel to buy it regularly. I'd suggest that for Toyota to say using E10 has caused the problem is BS. Look in the book - I'm sure it says you can use E10 (max 10% blend). I know my Holden book does.

DIO, biofuels DO reduced greenhouse gas emissions (slightly) and reduced harmful exhaust pollutants (slightly). Problem is that there seems to be no standards governing it's production (as far as I'm aware). However, the benefits are still not that great.

Hi Noddydog,

My work did the E10 assessment for Australian government. Most EFI cars handle E10 OK (air fuel ratio leans out but is within adapative limits of the engine management system). We did not test a Toyota Aurion but review of FCAI database shows that the Toyota Aurion is OK for E10.

FCAI - Ethanol Compatibility (E5&E10)

Your experience suggests that the EMS shifted lean beyond the adaptive window. Below are some thoughts on this:
1. I don't know where you live but if in Sydney/Woolongong area I know there is a problem with some rogue service stations selling higher concentrations of ethanol. There is now an active policing program to control this and recent prosecutions (some as high as 40%). This could lead to the problem experienced. Buy from a reputable supplier and you should be OK.
2. Ethanol is hydroscopic i.e. affinity for water. It may be possible your tankful of E10 had high water content, which would lead to misfire, etc.

I know you don't want to use your vehicle as a test case but it really ought to be OK on E10.

Regards,
Hugh
