Actually; I've just remembered that the Tesco 99 gets to that level (99 octane) by using a bit of Bio-Ethanol - so its Eco friendly as well!!!

Yes, found this piece on it earlier:

Tesco 99 Octane also contains low levels of olefinic compounds, typically less than 5%, compared with up to 18% in standard petrols. These compounds can lead to the creation of engine deposits. To ensure Tesco 99 Octane remains

I don't hammer my car as much as most but I have to say I didn't really notice anything when I was forced to use half a tank of 95 on top of half a tank of Esso 97 the other day. I normally use v-power just to be "on the safe side" and will continue to do so. Probably because I'm a gullible eejit.

You wouldn't know what issue of EVO that was in by any chance?

It was January 2006, the issue that got me hooked into Evo and away from Top Gear, Car and all the rest; they really do write a good magazine.

Right, just been out to Tesco and filled the car up and as soon as I turned the key in the ignition I noticed something. When idle, my car revs at about 11000rpm, which I have always thought quite odd and rather loud, but with RON 99 in it, it idles at about 7000rpm and is a lot quieter.

When pulling away, the engine definately seemed to be less 'gruffy', for want of a better word and certainly felt a bit smoother.

After a quick 10 mile burst during my lunch hour, I have to say, the 4p premium doesn't seem too bad.

I am new to this game do all tesco have 99 ron and have you tried the shell v-power:eek:

I honestly don't know which Tesco garages sell 99. I would have thought all of them, no?

And no, haven't used Shell V-Power. Until yesterday, only 95.

Nearly all garages in Ireland sell only 95 octane. Even the Vpower sold here is 95. Where I live there are zero garages doing 98, so stuck with that. To be honest the cost is not worth it in my opinion (it's a good 20-30% dearer). Used it on my last RS when there was 1 garage selling it, and I didn't notice much of a difference between it and 95. If people are that fussed about it over here, I suppose they could buy these octane boosters I remember one that a local shop sold...nitrox !!

Does anyone use any of these engine fuels cleaner product you see in auto shops. STP I think.

They are "going over to it". Up to last Autumn our local Tesco sold 97 Super Unleaded, then changed over to 99.

Excellent, thanks! This will help me win an arguement at work!

Where is Herts are you?

Knebworth.

Following this thread on for those Briskodians that do not have a garage within easy reach offering Shell V-power or Tesco 99, it is always possible to 'sex-up' regular 95 or 97 octane fuel with an Octane Booster. These are fairly widely available in your local motor factors or on-line.

Personally, I have used Millers Octane Plus for some years. This will generally add 2 octane points, so regular 95 octane will become 97 octane 'super' or 97 octane super-unleaded will become 99 octane.

How much of that CVL turbo stuff is needed in a tank-full of petrol?

I believe it's one bottle (500ml) per tank of fuel 40-50 litres but BEWARE, and I've spoken in the past to the guys at Millers, anything more than occasional use will fry your cat! :eek:

For regular use; stick to the Octane Plus at one bottle (250ml) per tank, a little less 'bang' but at least your cat will live. :thumbup:

Thanks Bahnstormer, so it would be more economical to use high octane fuel as opposed to boosting up 95. I suppose this product is for people wanting to boost 98/99.

Yup, I suppose; with Octane Plus at £4.75 inc VAT per bottle (RRP) into, say, 50 litres = 9.5p per litre extra. Whereas 95 regular vs. 97/98 super is generally 6-7p per litre extra.

On this basis Octane plus will only be vaible economically if you have to drive miles to get to a fuel station with 97/98 super OR if, as you suggest, you are someone, like the driver of a Japanese spec Scooby, who needs to boost 97/98 to 100 octane OR like me someone who uses it 'cos I want to. Unless you can get Octane Plus at a discount that will balance the equation.

Just have to say, after a trip to the NEC in Birmingham to see Keane on Friday with a full tank of Tesco RON 99, I have to say, I am impressed.

The car had much better pick up, the engine seemed to be quieter (see my comments when I first put 99 in) and, the fuel consumption actually seemed a touch lighter and despite only having a 1.6 FSI, got home to Peterborough in 90 minutes which isn't bad after coming out of a gig there.

Well chuffed. Won't be going back to 95 now.

NEC to P'boro in 90 mins - What kept you?

Seroiusly; in the early days of 'Cat' equipped cars I had a 1.6 Astra with a plug under the bonnet to switch between 95 & 97 octane fuel (I think it actually retarded the ignition a degree or two to stop the engine 'pinking' when on a diet of 95).

Running on 97 octane fuel always gave sharper performance AND generally I would get 2mpg better fuel consumption (something like 31mpg on 97 and 29mpg on 95) and that was with NO difference in driving style. QED.

Good luck.

NEC to P'boro in 90 mins - What kept you?

That's spending 15 minutes in teh car park waiting to get out of the place ;-) Have never been home before one when after a trip to the NEC.

After my crash in my Fabia in 2004 (after a gig in Manchester), I am a little cautious at times, for fear of another blow out.

Seriously; An instanteneous result is a bit odd as you will always have fuel in the pipe between tank and engine that will last for half a mile or so;

Nope. All modern fuel injected cars have a high pressure fueling system that effectively recirculates the fuel to the tank.

Also, AFAIK, 95 octane fuel can be used in VAG 2.0 TFSI engines, and I believe that higher rated fuel is only specified so that the engine can deliver its promised 197 bhp. At the end of the day, all modern cars have knock sensors that activate advancing or retarding the iginition timing to suit varying fuel grades (within limits).

If you believe a few extra BHP make a perceived difference (or measurable, in terms of say 0-60 or 30-70 times) then spend the extra cash if you must. If you do lots of miles, or are generally on a budget, or wish to have a slightly lower carbon footprint (because of the refining process, not mpg), then buy the 95 octane - day to day, you'll still have a fairly fast car for a family saloon!

Tesco higher octane does a good job for my VRS....and its cheap (try and avoid the crud they just decided to unleash on their unwary customers tho' LOL)

It looks like Greenergy (25% owned by Tesco) who supply the high octane fuel to Tesco for their super unleaded as well as ordinary unleaded are being closely looked at - they put 5% bioethanol in super unleaded and also supply a 5% mix unleaded (but it is sold as an ethanol mix not ordinary unleaded) and it has been suggested that a far higher mix of ethanol in the fuel (nobody has been specific as to which one it is or isn't or if it is all) is the cause of these engine failures. Still early days but I'd be a bit wary of putting in any Tesco (and some independents including Jet) fuel until it's sorted.

Today's newspaper suggests it is 95 that is affected.

Did any Tesco 99 octane [or any other super unleaded] user on this group have any trouble related to the fuel contamination scare? Or did they work out it was only found in 95?

I didn't have a problem using Tesco 99, BUT, went to fill up today and they have stopped selling 99, apparently some problem with it and they don't know when it will be back on sale.

That's all they could tell me :thumbdwn:

So, using 95 again (just for going back and forth to work), will it do any harm using 99 one week and 95 the next? Not sure how many sales outlets are affected or if it's just my local one.

Also, noticed that BP have put a couple of pence on a litre of unleaded round my way, thieving *******s. Don't miss a trick do they?

I'd not go back to 95, go for Sainsbury 97 instead, or similar, till they get Tesco back to normal.
