Petrol type poll for GTI owners ::please vote::

[4wheels]

That is correct. If you've looked at the thread 10 times, then that's 10 views on the view count.

Not to mention that not everyone who views the thread (with interest) may own a MkVI GTI, and therefore won't vote on this particular topic. What sort of petrol do I put in my TDI transporter? None, I hope!! But I'm interested in peoples thoughts on fuel types.

Fair enough.... I've been trying to find an old one that I read from BMW too, but can't right now.

Dammit, so much for going by the recommended octane. First tank was filled with 95 ron. Nothing but 98 ron from now on.

I second the recommendation for Caltex fuel. I'd risk running out of fuel on my bike getting to a Caltex over the other brands. Had a bad experience with Mobile a few years ago, and despite trying, they wouldn't even consider sending someone out to do a spot check. Apparently it's all tested prior to leaving the depot, and nothing else could possibly be wrong.

Anyone from Sydney filled up their GTi's with unleaded 100 yet?

Was wondering if the performance increment was substantial.. Can the Mk 6 GTi use 10% ethanol fuels?

Can the Mk 6 GTi use 10% ethanol fuels?

Volkswagen say all of their cars can use E10 - except for Lupo, Polo, Golf, Bora and Touran models with first-generation FSI engines built between 2000-2004 and in some cases until 2006, which can only use Super Plus* E5 (source).

*Super Plus = 98 RON

Well, if you can find more than one outlet in Sydney that sells 100 RON (E10 or not) do tell us!

[moonblade87]

haha i was wondering whether someone actually took a drive down to blacktown to get the car filled seeing as they are the only ones who provide 100 RON

[GHW]

I do not for the life of me understand why anybody would put anything less than 98 ron in any car let alone a Gti? tight as the proverbial fish....

There is no real benefit in some cars. With a couple of cars (one minimum 95, one minimum 91) I tried all fuels from the minimum up for about a month or so each. For the 91 RON car, it was marginally smoother the higher the octane but no fuel savings (was actually slightly worse on higher octane but not huge difference). For the 95 car, there was no noticable difference in performance and only marginally improved fuel consumption. If the car isn't capable of 'understanding' the fuel, then you may not get any benefit.

I don't think GHW meant that you use 98 for the "better performance or economy". You use it because you've just spent $40 to 60k on a car, and so why wouldn't you put the best quality fuel available into it?

Regardless of what the min RON is for the GTI in Australia, what separates 95 and 98 from 91 in Australia is the lower sulphur content (max 50ppm instead of 150ppm). But then what separates the 98 from the 95 is that the 98 has cleansing additives which clean and prevent harmful carbon deposits from forming on your engines internals (especially valves).

So when there is what, 5 to 7c difference in price, on a 55L tank that's $2.75 to $3.85 difference!
Is it realllllllllly worth saving $3.85 a tank on your $40,000 to $60,000 purchase?

BINGO ! EXACTLY what he said....

There's a site based in Germany called Spiritmonitor.de mentioned in this thread. You can see each user's log of fuel fill ups in detail and even do searches - and one thing I noticed is that the ratio of drivers using 95 rather than 98 is about 9:1, 6:1 and 3:1 for the 90TSI, 118TSI and GTI (155TSI) respectively.

Even with the Mk5 GTI (147FSI) and GTI Edition 30 (169FSI) the ratio is only 4:5 and 3:5 respectively. Meaning that for every five people who fill up with 98, there are four that fill up with 95 - despite VW clearly recommending the former for these engines.

I suppose it's not surprising, given the minimal difference in consumption and the sky-high price fuel of over there. Superbenzin (95) costs $2.30 per litre, while Super Plus ( 98 ) will cost you 12 cpl extra, at an eye-watering $2.42 per litre! (source).

You can only conclude that the main reason for using 98 is for more power, and with petrol being sooo damn cheap as it is in Australia, why use anything else?

But then what separates the 98 from the 95 is that the 98 has cleansing additives which clean and prevent harmful carbon deposits from forming on your engines internals (especially valves).

May not be entirely true. For example, BP unleaded 95 has a "lower additive treat than BP Ultimate", and BP unleaded 91 has a "basic additive treatment". Caltex and Shell also say something along those lines, so they're not completely devoid of cleansing additives.

The one unfortunate aspect of FSI/TSI engines is that since the fuel is directly injected into the combustion chamber, the one area where it can't do the much needed cleaning are the valves.

seems that the petrol marketing guru's have worked wonders on you guys....

[GHW]

Seems more like you're one of the tightwads I'm referring to.

[entice]

yeah I must be...
i seem to be so tight that I hold on to my cars for all of 11 months and then turn them over.
when you've owned so many, at the end of the day, it's a machine. so long as it lasts me the 11 months, I couldnt care less.
But that's ok.. everyone else can put the most expensive fuel for their daily driver.. I prefer to save the martini and elf for the track car personally, and if there's any coin left over, that can go into appreciating assets rather than depreciating liabilities.

If it could run on 91, then that's what I'd be putting in it. stuck idling in traffic, it makes no difference....
