unleaded, pref 98 - BP, Shell, Mobil.  No additives but let's see what the chemists say... Stu, Doug, Neil??

What do you guys think of the 'generic' premium fuels? The ones just labeled 'premium', that don't give a RON rating.

I've been filling up at the same Ampol service station for weeks now, putting in tank after tank of 'Gold' fuel. Can't say I notice any difference between it and fuel from BP or the like.

I've tried almost every petrol there is and in my opinion, Mobil Synergy 8000 is best. If you can't get a hold of that then BP ultimate is option 2. In my experience, shell is rubbish

Put any petrol you want in it, it doesn't matter if its BP, Mobil, or Shell, or Ampol, or Caltex. Definately run it on 98, just dont ever put in that Ethanol crap, unless you don't like your fuel lines...

Just rev the crap out of it, that always fixes stuff... 

Hey Sheldon

What cambelts on a '83 2.0L GTV.  Unless I am very much mistaken you mean camchains, don't you ??  But definitely true re dodgy doughnuts.  I had that delight (ting ting ting !!) on my Gt many years ago.

As to fuel types despite all the learned comments on this thread I am not convinced you need to use 98 Ron, let alone the value in the extra cost of this fuel.

I have been using premium 95 Ron plus flashlube in both the Berlina I used to own (RIP) and my 1750 GTV since leaded fuels disappeared from our shores.  Why the use of flashlube, simple...cheap insurance. Frankly I have never noticed any problems with any of the fuel suppliers, be it Shell, BP, Ampol, Caltex. Down here in Tassie it is all the same anyway, and simply dfferent distributors.

As to the comment re the use of ethanol, I would actually like to see some empirical test data to prove conclusively whether or not this is a problem.  As a scientist, but more importantly having owned Italian cars all my adult driving life (31 years) I fail to see where the problem may be. 

Ethanol has been used around the world for probably the past 20+ years and apart from heresay and inuendo I havn't actually seen any hard facts. I have tried the ethanol blend in my '03 JTS 156 and similarly have not noted any deterioration in the car's performance.  Lets face it the blend % as I recall is about 10% here in Aus.  In Brazil its 50% !!  Having said that I do use premium 95 RON in the 156 mostly.  From what  recall about ethanol, as similarly methanol, it is supposed to actually increase one's power output while reducing harmful emissions associated with petroleum based fuels. Happy to be advised otherwise if there is some credible data to show problems with the use of such blended fuels.

Not to harp on too much about climate issues associated with the burning of fossil fuels etc in this forum but I think in the end there is going to need to be a paradigm shift in all of our thinking towards bio-fuels.  Perhaps this is a topic for another thread though.

Enjoy the GTV Pete and welcome to the forum.  Cheers Dave

Thanks for clearing that issue up GreenGTV8.  I had wondered re the difference. Cheers

Na, 3years ago i started designing a car(on road/meet ADR's)from scratch and am now building the first one. Full space frame, and a long list of features, but i decided to use the Aurion/Pesara for it's electronics and drive line as i needed a new car engine to meet emissions and noise tests. Also Pesara has blue tooth, sat nav, voice activation, keyless everything, touchscreen intruments, so on and so forth, and a long list of stuff that would be fun just to put in cause it's there...
       If your building from scratch...you build a race car...or you build a road car...and i'm building a road car, hopefully a very nice one, but time will tell and we'll see what happens.
