Fuel Experiment with a 6L

[iUte]

I only run the 98 RON fuel on my car, my mechanic told me too, because thats what its tuned for.

I tried running the 85 stuff, but it ran rough compared to usual. Which is a shame because the Vortex or Ultimate are over priced IMO.

Specially since it costs the petrol companies the same amount to make either type of fuel.

[Nuddy989]

or diesel is a by product of making petrol as in they can't make petrol without making diesel yet it's more expensive

[kato128]

Here's the stats I got from the 1 tank I put in of e10

Range: 464KM
Cost per km: 19.9c

More expensive than e85 per and the car ran terrible on it. It's not as accurate as the previous data but I can't bear making the car run like that for 4 tanks worth.

On a side note the performance really picked up on the last 8th of a tank or so. Guessing that higher octane fuel floats to the top...

not necessarily in a 6L but interesting to watch when talking about fuels..

OK guys updated the first post to include new results. Here they are again.

BP Ultimate:
Avg Range: 499km
Avg cost per KM: 19.7c

what about 91 ?

[aaronevolution]

what about 91 ?

Why would you use 91 in a 6L?

I wouldn't put e-anything in my cars, if you have ever opened the fill or dip hole at a servo and are greeted with the pungent smell of fermentation, just the same smell as my home brew room, you'd think twice.

Ethanol is so strictly monitored and tested, ie, before being loaded at the refinery, after loading at the refinery, before unloading at the fuel terminal, after being mixed with the petrol at the terminal, after being loaded into the tanker at the terminal, then gets thrown down some dirty hole in the ground and forgotten about for who knows how long until you pump it into your car....er, no thanks.

sorry, I read this thread as about the cost per kilometre of running this factory car on different fuels. So I just thought it was logical that 91 would also be tested given that holden has spent many hours and much $$$ to ensure it does run on 91. But what would they know, they just made the thing and did a million kilometers of testing.

I doubt they would have tested their new Gen 4 V8's on 91 octane fuel.

[vongy10]

It's a performance motor so 98 would be the most recommended.

[yxyx64]

I doubt they would have tested their new Gen 4 V8's on 91 octane fuel.

Thankyou for your advice. How foolish of me to even think that holden would have ever put 91 into a gen4 to see what would happen. After all, once the engineers have ticked off on the drink holders you probably do not have much of the development budget remaining to really test anything else.

Do you think it worthwhile contacting holden to tell them that 91 octane is sold in Australia? I mean so they can test the cars they are developing now that they want to sell in the future.

Interesting

Not in NSW anymore its not, and if the car manufacturers and oil co's get their way, nor will it be anywhere else in Australia soon.

its all good mate, just as the federal govt says they wont do something and then do it anyway, our newish nsw govt gave a flip (and a stay of execution) to the upcoming changed petrol regulations (which was never designed to get rid of 91 but was going to add ethanol to it). so you can still buy (and in the future) 91 petrol that has exactly the same energy content per litre as straight 98 fuel. (Calorific value if you like - of course RON varies but that is by definition)

[frogsta]

Any chance of a comparison between the big 98 octane brands/fuels?

So far it seems BP ultimate is the best?

be careful what you want to actually find out as it will get very messy very quickly. For example, if you live in Tasmania then all your Mobil fuel is rebranded Shell from the Shell Geelong refinery. Whereas for you in Western Australia your Shell is not made by Shell at all - rebranded under buy-sell arrangements that all four refiners in oz have. Shell rarely imports product to WA. BP runs the refinery near you at Kwinana - the ONLY refinery in WA (except BP can also import through its terminal at Kewdale when it maybe wants to get a little of the Malaysian or Korean product). So take a guess what your Shell product really is in WA.........

[Loaded Dice]

FWIW e10 is 94 RON. Close yxyx64, BP has no refinery in Vic, so most of BPs product comes out of Mobil Terminal with BP additives. Whereas in Brissy, there is no Mobil Refinery, so they load out of BP with their additives on top.

About the only one down south that actually only sells what they produce, is Shell, but funnily enough, Shell don't own any servo's, Coles Express are owned by Wesfarmers, and if it is a Shell servo that is no Coles Express, you can not buy V Power there, oh and Coles Express don't sell e10 (or e-anything) in Vic anymore, like yxyx54 said, starting to get messy and thats just the start of it lol.

FROGSTA lives in Cockburn. Read the reply again and you will see the BP/Shell reference is Western Australia based for FOGSTA. I do love it though when the facts turn the whole premise of the arguement inside out. Pity then a lot of people will not believe people like us Loaded Dice. I think I see where you are going with BP VIC but I'm pretty sure in spite of Altona that all Tasmania Mobil is Shell supplied from Geelong.

I would still like the OP to do a trial on 91 and see what happens. He does need to price adjust though as the test is now taking long enough that the original prices have crept up (adjust for inflation if you like - or bracket creep if you prefer).

How about you go and spend $50,000 on a new SS, and then go against manufacturers recommendations (and void your warranty), and run a 91 octane fuel test yourself.

[m1lky]

Doesn't the manual also say not to use ethanol fuels? Thus voiding your warranty?

No idea. But I'm sure if you took your car to Holden under warranty with a ####ed engine with the wrong fuel in it, they might have some words to say.

The handbook for my MY12 Redline ute states it can be run on E10, E85, 91, 95 and 98.

Its rated output(260kw auto, 270kw manual) is with 95 octane.

Yeah sorry, perhaps you were editing your post while I was replying, but regardless, I'm sure that there are people outside WA reading this thread with interest.
