Shell's new Optimax 100

[Amaroo Park]

Has anyone here used the new Shell Optimax 100 octane which has 5% Ethonal in it? I saw it today for the first time. It was 9cents per lite more expensive then normal Optimax

That is boardering on requiring a trip to the tuners!

Yikes.

Dear Shell,

Please find enclosed a bill for the replacement of seven melted pistons.

Sincerely yours...

I have heard about it but have never seen a pump - not that I look as I still use 91ron

It is hardly worth the price that Shell is asking for over here. There is a lot of pressure on the Fedral Governmet from the Sugar Cain growers in Australia for the government to pressure the oil companys to use ethonal in petrol

Well i used 98 octane in my older car, and i notice the difference

91 octane makes my car run like a tractor.

Over here the government has just introduced a mandatory 10% mix of ethanol and petrol, also bowing to the influence of sugar cane growers (and fears of dwindling oil reservoirs). Have to say that I'm happy so far. I always use regular and pinging has decreased dramatically. Don't know about the long term effects though. A lot of people have had breakdowns because of clogged filters and broken hoses though.

i'd like to try it, but my supra always runs like crap when it gets filled with 98RON shell optimax, I don't know i want to possibly waste a tankworth of petrol when I could stick with bp, mobil or caltex quite happily (and other owners have tried it and noticed no difference, even with ECU reset to force adjustment of ignition timing to the new fuel)
