Tesco Momentum all the way
I've read that Momentum 99 gets its high octane rating via a high bio-ethanol content which gives the fuel a much lower calorific value and really nails your fuel consumption. Any idea if that's true?

I'm in the UK so yes, 95 is 'standard' for me and has been for some time in this country. However, 95 is by no means unrefined 'cheap' fuel and......I just have issues with manufacturers who weasel their way through wording to try and cover up their problems. It certainly shouldn't be happening on an expensive car people are paying a good premium for. It isn't even their high performance engines they do this on, it's all their TFSI engines (certainly when I last looked).Okay this makes a bit more sense now. What country are you based in? In the UK 95RON is classed as premium but it's generally the lowest grade if fuel you can buy, I've certainly never seen a lower grade of fuel anywhere I use. Hence why I'm basing my 4% on the difference in cost of premium to super.
I haven't used V Power for some years, but I can remember filling up once when I was desperate in a really bog standard 1.6 Astra Club, 115PS, nothing special at all. I have to say the effect was incredible. I wouldn't fill up purely for the economy reasons but that fuel turned what was otherwise a totally boring car into something incredibly smooth and enjoyable. I used to have a Shell garage not far from me but now it's BP.....I try to fill with Shell V-Power wherever possible just to give it as consistent burn properties as possible. That said I've got a week in the North-West highlands coming up soon and finding V-Power can be a tad tricky!
Nope, but I certainly wouldn't want to shove additives in myself and these engines are way to complex now. That's why the fuel companies have massive chemistry departments.As a related point the owners manual advises against "octane-boosters" as they can contain heavy metals (4 star anyone?) hitch can damage the cats. Any experience on this?
Hi guys, this is a good little post as i'm most OCD with good fuels in cars, in my current 1.4 naturally aspirated I did use premium but didn't notice a notch of difference so I use normal.
Can anyone answer the question of is there much point in filling a 1.4 TFSI 150ps petrol engine with premium? Being Shell V-Power, what octane rating is the normal against premium if anyone knows that also?
I would imagine there would be a good side to fill it with premium, being supercharged and turbocharged but it is only a 1.4, so maybe no point? Am not too familiar on the technology of that, all a bit new to it.
Cheers.
Waste of money, no gain at all....Hi guys, this is a good little post as i'm most OCD with good fuels in cars, in my current 1.4 naturally aspirated I did use premium but didn't notice a notch of difference so I use normal.

Have a good read through this thread mate and the links I've posted.
In short I'd put momentum in yours yes, normal is 95, momentum is 99.
Ahh, sorry, I did read through for some way but obviously not far enough thanks.
What evidence have you got that it will under real driving condition, there is none out there I've seen that has convinced me to use anything other than supermarket fuel....Based on what evidence? I seems quite plausible to me that it could make a difference as it seems to in many small displacement turbocharged engines. It's surely a question of whether it makes significant enough of a difference to warrant it and that's probably going to come down to personal choice. You're not going to break it with 95, you're not going to get a huge increase in bhp with 98/99, improved fuel economy might balance out some or all of the additional cost though.
For me, I do 10k miles per annumn and I'm paying £450+ per month for my PCP, a few extra quid a month for super grade is not a huge part of my motoring costs. I know my fuel isn't holding the engine back in any way, I'm following Audi's recommendation and hopefully I'll get back some of it back by squeezing out a few more miles per tank. If I don't I'm not losing sleep over it.
Overall, I would agree. I have V-Power in a petrol right now for the first time in years and it's made driving quite a bit more pleasurable and much smoother, but I'm not seeing any appreciable gains in economy.Waste of money, no gain at all....
I'm not suggesting they don't just that in the case of direct injection engines whatever they're doing historically hasn't been enough, and it is a known problem regardless. Anti-knock systems can only do so much and you'd rather they weren't relied upon. Mercedes had terrible problems with their DI engines and VAG continued in that vain. I suspect they're pushing the boundaries too much for the sake of fuel economy and performance. The pistons have a tendency to cavitate over time with detonation at high revs under certain load conditions causing wear and tear. Cold compression problems are usually the first sign.You do know that all modern engines have their ignition and valve timings controlled electronically and have anti-knock sensors because you seem to be suggesting that they don't.

I never believe what the stealership tells me, they don't have a clue. All they care about is getting your money off of you.
Yup five years, or many many debates on several forums and still nobody has reproduced any of the claims made by the oil companies that produce these products, so no proof exists what so ever. And seeing as direct injection has been around for years it is unsurprising that individual car manufacturers might have had design issues around their systems however that doesn't mean that all direct injection engines will suffer significant problems at all. If they were then Internet would be screaming it out.I remember this argument nearly five years ago now, still hasn't budged much!!
In terms of real world pricing for 10k miles a year its about £170 more per year (or £15 per month) for peace of mind. If the price difference affects you I see no harm in the standard fuel, for a car like the S3 its worth it if max performance bothers you.
In my experience I noticed very little difference because my journeys are short and I don't tend to push to the limit daily, or much at all.
Any suggestion guys?I'm looking forward to order a S3 Sedan through the end of the year. I'm reading reviews and other S3 8V issues here and this forum is helping to learn a lot, thanks guys. Here in Turkey, we have a serious fuel quality problem. We don't have 98RON, we used to have 97RON which was Shell V-Power Nitro. I don't know exactly why but this is not available right now. 95+RON with additives is the best option that we have at the moment. You might know that some countries can not receive S3 Sedan with 300HP and here it is coming with 285HP. I just wonder, if I use the car with that unknown 95+RON fuel, how it is gonna effect the overall of the car? I mean engine's condition in long time, power etc. Moreover, it doesn't make sense to spend that much money for far less power than 300HP. What do you think and suggest guys?
Thanks in advance.
I think there's enough information here for you to decide not to do it unless you can get 98 RON. If not you're going to end up with a pretty hefty bill out there somewhere.Any suggestion guys?
Thanks for reply. What's the worst scenario?I think there's enough information here for you to decide not to do it unless you can get 98 RON. If not you're going to end up with a pretty hefty bill out there somewhere.
