100 Octane

[Oversize]

Noticed today that United in Point Cook is selling 100 octane fuel and that their 95 contains 10% ethanol. While I'll stay away from that, I wonder if 2 octane above Shell and BP will make any difference??

 

[abl567]

Does the 100 contain ethanol?

 

[motec 6.9]

YES IT DOES. stay away it will perish all your fuel lines if not designed for it which on old cars they are not.

As I have said before used to work for Mobil in 90's . Still have friends in trade all 100 in Australia contains Ethanol .

 

[Oversize]

Really? It didn't say it contained ethanol... I'll have to go back and check!

 

[motec 6.9]

No need here is your answer http://www.unitedpetroleum.com.au/united/fuel/premium-100

I once put it in one of my cars and noticed that there was a sign saying it contained Ethanol (afterwards). I asked the cashier if it did, and he said no. I checked the website and it says it does, so I went back and told him.

Hi Craig I used to drive a delivery truck in Canberra for Mobil. As I said I still have friends in the trade . All 100 octane in Australia has Ethanol.

If it doesn't state clearly I'd be getting them to pump my tank

All 100 in Australia comes from Shell and it does contain Ethanol. United bought Mobil service station assets . It remains to be seen if other assets remain in Australia.

Shell in Mickleham used to sell 100 racing fuel. Would that have ethanol?

 

[motec 6.9]

No racing fuel different. Its 100 octane Shell started selling in normal service stations that is Ethanol. I wouldn't worry as 98 would most likely be better as Ethanol increases fuel consumption as it has less Calorific value but higher octane. meaning less bang per Ml of fuel but higher octane means higher compression or ignition advance to benefit from the octane. http://www.engineeringtoolbox.com/fuels-higher-calorific-values-d_169.html

 

[Oversize]

I think they stopped selling it there anyway... Pity! It doesn't even look like you can buy it in drums anymore!

[motec 6.9]

98 is good enough unless you are going 11 plus on compression Mark.

 

[CraigS]

I use 95 in everything from the 300b to the E320.

 

[motec 6.9]

Hi Craig Euro 6.9 was specified to run 98 which was octane of old Super . But like I told Mark unless 20psi boost or 11 points or more compression anything higher is a waste of money.

 

[SEL_69L]

It seems to me that Australian100 octane fuel is simply a blend of 90% 98 octane and 10% ethanol.

If that assumption is right, DO NOT put it in older cars, where the fuel system, (in particular, any flexible fuel line), is notdesigned to take a fuel with ethanol added. That is, DO NOT put 100 octane in the fuel tank of a 6.9, for example.

 

[Oversize]

Yes unless it's racing fuel....

 

[motec 6.9]

Hi guys its something I knew about But assumed it was common knowledge that Ethanol was in 100 octane. Apparently not as David said it should never be put into a W116 as fuel system is not designed to handle it.

The last two years I have only been using BP 95 Octane to fill up the car.

95 Octane was $1.70 per litre was week and 98 was $1.80 per litre.

Also use 95 when filling up the Yaris.

I have Mercedes owners filling up there car with 100 Octane the car was a 450SL W107.

Did see a guy at the Salamander BP filling up his beige 230E W123 with Octane 91!

91 Octane and 100 Octane in two of the older Mercedes recipe for disaster if you ask me?!
