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

[JordanNaumov]

Hi Guys and girls,

Now i know this is a debate that will never end and i know there are a million existing threads on the topic but i want to see the percentage of people that use regular petrol to the people that use premium petrol in their cars.

REGULAR = 91 octane 'Regular Unleaded'.
SEMI PREMIUM = 95 octane 'Premium Unleaded'
PREMIUM = 98 octane 'Premium Unleaded' - BP Ultimate / Caltex Vortex98 / Shell V Power / Mobil Synergy 8000

...which one are you?

[118TSI]

Reckon this thread can apply to any Petrol powered Golf, will be BP Ultimate all they way for my 118

I think this would have been more clear if the options for the fuel types mirrored something consistent with what they're actually called.

So I've edited the first post to reflect this....

Why wouldn't you use Premium (9 in a GTI?

Yeah much better

There is no option for multiples.

I use both 95 and 98.

First few tanks were 98 and i filled with 95 once and got an extra 100km out of the tank. Given that im doing approx 100km per day to and from work unless im planning to go out for a drive in the hills or something i use the 95. I have not notices any significant performance drop, and contrary to the flyers on ultimate, get worse economy on 98.

Then about every 3rd tank i get guilty and put 98 in again for another comparison, but i really cant tell the difference after nearly 5000km, and i dont pussy foot around in it either.

Really? I have never done the comparision and just used V-Power or BP Ultimate. Anyone else actually do a comparison?

Personally you are crazy to use 95 in the car if 98 is available. The long term effects on engine wear & tear, carbon build up etc are not worth the few cents per litre (IMHO). All you have to do is take VCDS on a stock car & look at the difference in knock & timing pull when you run the two different fuels. For a real test, run 95 ron on a 40 degree + day.

I 100% believe that VW have tuned the software in Germany with 98 ron in mind, and they have been pressured in the AUS marketplace to say "95 ron is OK"

BP Ultimate without question for me. I'll plan ahead to make sure I can get it where I'm going, and if not, I'll make alternate arrangements - like taking someone else's car.

The GTI is designed for 98 RON, I personally think the BP product is superior, and believe that my car is worth whatever premium is charged for a fuel that will allow it to perform at its best and keep it running as well as possible.

Being that this advice comes from Guy_H who I have a lot of trust in from all the work he has done on VAG cars and within the VW Watercooled Community, and the fact that he has actually provided a statement with some type of 'scientific' evidence behind it (well looking at VCDS information is hard data, whereas everyone else's comments are just "opinions" or anecdotal), I think this post really needs to be highlighted.

In relation to the cars being tuned to 98 ron in Germany and then "market pressure" having them dictacted to 95 ron minimum in Australia - I would also fully believe this. The fact that the original MK6 cars were marked as 98 and then changed after the launch would also seem to indicate this could be true.

Lucky I'm getting a BP card with the new golf

There is no way VW could say . . . "You must use RON98" . . . in Australia. Its simply not available everywhere in Australia. Its certainly available all around the coast and majority of larger inland towns , but, not everywhere. I would expect they would need to be able to use RON95 in need.

Isn't this exactly what they did when the Mk VI was launched? I was under the impression that it was only the change to the MY10 Golf that led to 95RON being labelled as being acceptable.

Further to that point, this CarAdvice article indicates that the GTI, R32 (and presumably R), Passat R36 and Passat CC all continue to require 98RON fuel as a minimum grade. That means, if you can't get 98, you should use octane booster to keep the engine happy until you can fill up with 98RON fuel.

This is what I'm concerned about. Basically, Volkswagen Germany (where the cars are made) are stating a minimum requirement which Australian fuels are NOT compliant with.
