Optimax Extreme 100

Chris:

With you all the way on that one mate.

Lots of Toluene = lots of black sooty residue - I often wonder what else is being deposited through the exhaust pasrts of the engine. Good dense fuel but Optisoot is the right name.

I always run my T on 98 octane. Was down to 40km range lasst night so filled up on Shell 100 Octane. $1.37 a litre at Shell Lidcombe (Parramatta rd). (Thank goodness for company fuel cards....)

Drove for 20 min last night to make sure all the fuel was mixed up...no probs.

Drove for 1 hour to work this morning including a couple of thrashes and no probs. Car goes hard, no pinging, if anything it feels like there's a bit more poke there.

My T is an 03 Auto build. Not edited but latest flash from Ford. 2nd CAI and Hitech exhaust & mufflers.

Will be interesting to see what happens once some edited cars use this fuel and then get an adjusted map. Would do it myself but still saving for the edit.

I'm off to Goulburn and back today so I'll arrive back in Canberra with low fuel, so I'll put some in and give a report.

$1.37 at Lidcombe will likley mean it will be more than $1.50 a litre in Canberra!. On driving back from Melbourne on Tuesday I noted that the price increased from $1.10/litre in Melbourne to $1.28 litre upon reaching the good old ACT - bloody rip off.

Have a bit of a look at this site. It tells you what cars can and cant run this stuff.

This a quote from the site....

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

Interesting,

The exotics, Porsche, Ferrari, Maserati (no Lamborghinni) do not

recommend any use of Ethanol.

Is there a specific reason/s for this or is just that these engines are so high

strung with minimal error margin that and any variance or imbalance could

be fatal to the engine or its components

Remember I speak from a very non-technical background.

ps. Turbo6man & KEN24T, thanks for your support...ride is much better now.

I filled up with Optimax Extreme yesterday, mind you I still had 1/4 of a tank of Vortex 98 in it. My impression so far is that it seems to burn cleaner and crisper. The acceleration comes on quicker when kicking down a gear which I'm guessing (and thanks to Dingah for this insight - correct me if I'm wrong Dingah) that it is more flammable. Seems good, but it was 3 cents more expensive then Optimax at 137.7 cents.

Cheers

so where are we getting the E10 fuel from and how goood is it ??

[mickq]

If I can I will grab half a tank full tonight and let people know how it functions in a car driven very hard.

I will be interested to see.

PS, people who are trying it, disconnect your battery for a few mins then re-connect it. If you dont do this, your car will take differing times before it adjusts timing to make up for the higher octane, so you will not necessarily be seeing the full difference. There is a pretty complex algorithm that's used to determine when the ECU makes a full adjustment to a new fuel - its not as simple as the moment it detects a change it alters timing. When you get rid of your ECU's volatile memory you force that to happen right away. Keep in mind you need to give your car a few kms of normal driving before evaluating - ie dont evaluate it the first time you floor it etc. Give the ECU a little time to learn the new fuel under different loads.

Doesn't adding ethanol to petrol make it cheaper. If that's the case then why the hell is it more expensive than Optimax. Rip off bastards.
