not tried 100 ron wow ! been running it on 98 ron, up until last fuel up where had no choice but to put 95 in it. definitely felt it was a tad robbed of performance. was very glad to get it back on to 98 this fill !

Correct me if I am wrong, but I swaer I read somewhere about 100 Ron, which is Shell V-Power, is 95 Ron Unleaded, mixed with Ethanol which get it to 100RON rating

[Diesel_vert]

"Shell V-Power" was and still is 98 RON.

"Shell V-Power Racing" was 100 RON with 5% ethanol, but unfortunately, no longer on the market.

United Petroleum still has 100 RON, called "Premium 100" with 10% ethanol, but unfortunately, unlike SA or VIC it's only sold AT ONE OUTLET in the whole of NSW.

What gives?!

Who's the muppet using 92RON?

[sports racer]

I'm one of the muppets.

I have an Aussie MK2 GTI with it's standard low compression motor and do 900 k's a week. Why wouldn't I use petrol that's 10c a litre cheaper?

Cheers

Just goes to show how long it has been since i have been to Shell. I stopped using shell 98 ron after we found a few WRX's at a dyno day were all pinging. Common theme was all had shell petrol.

During the first 18 months – 2 years of ownership of the MKV GTI, I used a Wynns Octane Booster for every 4th tank fill. Octane booster was primarily as a safeguard against a bad batch of fuel. Noticed a fuller feel to the MKV GTI motor, but doubt performance or economy improved.

I also used primarily Caltex 98 (Vortex) which was a great fuel. Occasionally I’d use Mobil, Shell and BP Ultimate.

Went through a period of about 6 months using Shell V-Racing 100+RON with 5% ethanol for every fourth tank full. Volkswagen at the time recommended no more than 5% ethanol blend. The Shell fuel added responsiveness with little or no noticeable effect on fuel consumption (Ethanol only has 2/3rds the energy of regular fuel, but increases power).

A friend of mine had drama with filters and fuel pump ... he lay blame to using Shell 100+ V-Racing ethanol blend. The Volkswagen service guys advised against ethanol blend as ethanol tends to clog filters & pumps they say – stick with the regular 98 unleaded. I stopped using both octane booster & Shell V-Racing and sometime later, I did receive a bad batch of fuel.

The bad batch of fuel was Shell V-Power 98 RON from Shell from Northborne Ave, North Canberra next to the Canberra Showground. I drove from Canberra to Sydney without drama as the drive is descending in gradient most of the way and the motor does not experience too much load – I know this as fuel economy is much better from Canberra to Sydney than vice versa.

On return to Sydney, driving up a long hill, not steep, just protracted, with about ¼ tank full of Shell V-Power 98. The MKV GTI started to cough & splutter, so much so, I was forced to take the exit for fear of not making up the hill. Straight to Caltex for a fill up. This rectified the problem to a degree, but same hill still had the GTI sputter & coughing, only about 1/3 to ½ as bad. The bad Shell fuel was diluted with good Caltex fuel.

Spoke to VW service re mechanical fault(s) ... no fault codes on the dash, so most likely result was bad fuel. Service guy recommended double dose of Wynns Octane Booster to further raise the octane level & clear the bad batch of fuel that probably had water in it.

I went for the Wynns Race Formula Octane Booster (5-8 RON +) and returned to the same hill for a third test run. GTI pulled like a freight train up the hill feeling like brand new.

I sent a complaint email to Shell advising them of the bad fuel and asking for a $20 refund for cost of Race Booster. The octane booster receipt was included in the email. Shell asked if I had proof of purchase (i.e. Receipt or Credit Card Transaction when purchase Shell fuel). I paid for fuel with cash & did not keep the receipt. I asked Shell to check their CCTV footage at that Shell servo as it would show me filling the tank at the servo. They informed me that the burden of proof lay on me, not them ... in other words; they weren’t coming to the party on anything unless I could prove that I bought fuel at that Shell servo.

No more Shell for me from then on.

As for BP Ultimate, BP has a terrible maintenance record in the upkeep of their drilling platforms and/or refineries. In addition, in Sydney - Shell tend to supply fuel to BP. I’m happy to stick with either Caltex (aka Woollies) or Mobil – probably Caltex for most of the time. I will also return to my old ways of adding an octane booster every 4th tank in case I receive a bad batch of fuel, once the MK6 arrives.

Cheers.

You're right about it having less energy, however ethanol increases octane not power.

Many years ago I worked in a servo, and the tanks had to be checked daily by pulling out the giant dip sticks. You were supposed to empty the water from the little pit that contained the dipstick, but in the middle of winter in the rain, it rarely happened when you had 6 tanks to do. So the water / sludge simply went into the main tank whenever you took the cap off. Some blokes never bothered regardless of the weather.

The thing I learnt from that is to buy your fuel from a servo that sells lots of it - high turnover of petrol (i.e. plenty of fresh stuff being delivered) is a good thing.

[Diesel_vert]

Moral of the story - ALWAYS ask for a receipt when purchasing fuel (esp. diesel), you never know when you'll encounter a bad batch.

You don't want to be left with a potential bill in the thousands from damage to injector pumps and whatnot caused by poor fuel.

Because if do run into trouble, you can at least make a claim to BP and Shell (don't know about Caltex and Mobil).

I'm one of the muppets.

Luckily, being a Mk2 owner, you're within your rights to use 92RON Paul..

But this being a MkVI poll, I'm dying to know who the other cheapskate is using fuel below the VW minimum recommendation or who can't read properly...

Dear Mods,
Can we please consign this thread to oblivion as a waste of time and bandwidth.

I would suggest almost all people who subscribe to this forum would be VW enthusiasts and as such would treat their cars to "the best", hence the poll result which was entirely predictable.
The percentage of respondents would indicate that most people know this and couldn't be bothered replying.
Lets get on with some meaningful topics please.
Regards to all,
Brian

Brian, would that be the same for every other thread on this forum with well over 1000 and only 20-50 replies?
reason i ask is because there are many threads like that, so do we do away with all of them?

Presumably each time a thread is updated with a new reply, and someone reads the thread again for that reply, the view count increases. Thus it is arguable that the view count has little to do with the vote count.

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