Ive been running my vrs on shell vpower petrol

Has any one else used this and seen any benefits.

Or is normal petrol just as good

I use BP ultimate diesel, but you need to run a few tanks to notice the differance.

Petrol, I've heard tesco momentum ( 99 Ron ) is better than V-power, but only with what I've heard.... Wouldn't touch supermarket diesel

I used to use 98ron in my bike when I had one and noticed the difference-it was smoother and had better throttle response so I'd expect the vRS to be similar. Only way to be sure though is to run a few tankfulls through to see if you notice any difference.

Oh and my honda lawnmower won't run on normal unleaded- it has to have SUL ...LOL!

I only use Super in my VRS - Usually Tesco as I have to go past the petrol station to go out and go home, also use V Power of I'm out and about.

Wouldn't use "normal" unleaded unless that was the only option.

After a few tankfulls you will find that you can go round corners in a higher gear and the car just pulls away with no complaints - what you would use 4th gear with "normal" you will find you will be using fifth gear with SUL and not even noticing.

I seem to get an extra 1-3mpg with SUL, but that might just be the driving/traffic for that specific tankful, however last w/e I went on a family visit to Rochdale, doing just under 450 miles round trip and only using SUL I got 38.9 (at 70mph of course.... :think: ) and when I did the same trip when I got my VRS last November with "normal" unleaded in it, it was 35 point something - so for me SUL is miles better for the car and worth the extra.

Besides - coming from a 325bhp Scoob with 24 mpg on a run if you were being good, to the VRS, the extra cost for SUL isn't a problem!

You should notice a slight improvement using higher octane petrol over standard.

But the V-power diesel doesn't make any difference to performance.....except it's slightly less smokey.

On my car the sticker on the inside of the filler cap states that the minimum specification of petrol you should use is 95 ron, i.e standard Petrol, what i've just started experimenting with is say 1 week 25 lts of 95 and the following 25 lts of 99, in order that i have on average is 97 ron in the car, this i feel is slightly better for my car and my pocket..one thing for sure is that my car does run smoother and i have small increase in mpg..

This post gets posted again and again and again :(

Do a search - This has been talked about at least 30 times - Some good info out there.

I ran a test on my petrol vRS on this a while back and basically my (unscientific) findings were that V-Power improved perfomance and mpg slightly over standard 95ron shell, while Tesco Momentum was slightly better again. However BP Ultimate and Texaco Super made no noticeable difference at all,

All this was done by running at least 3 consecutive tank fulls on each at a time.

That was all done when I was running a Bluefin Stage 1. Now I am running Stage 2 (with DP and sports cat) it is tuned to use 98/99 RON and I suspect putting 95 in will diminish power noticeably.

If I was really worried about the cost of fuel and running a standard tune I would just use 95 RON to be honest. But I'm not so will only put something other than Momentum or V-Power in if the only alternative is walking

Just something to think about. Im also stage 2 and was getting multiple cylinder misfire under hard acceleration. At that point I was using Tesco 99, but after switching to V-Power, it has not happened since. Im running Revo software on performance mode 3 (normally for 120ron fuel). I'll happily forgo the extra Tesco points.

As mentioned in other threads, 5th gear tested different normal and higher octane fuels in a back to back test in a golf GTI. The result was there was no noticable improvement in power. From memory there was only a difference of 2bhp on a 200bhp car from the cheapest supermarket 95ron to top of the range 99ron stuff. In conclusion its pointless. This was proven a rolling road. They also did driver assessments but i cant rememebr what their conclusion was as for me the dyno read outs summed it up for me.

If you put someone in a car and say its got "super" fuel in it they will probably convince themselves it feels faster despite feeling no different. Its all kidology.

There may be long term engine benefits i.e cleaning and protecting but i have see nothing to confirm or disprove this but if true then this would certainly be a more beneficial feature of more expensive fuel IMO rather than non existent performance gains unless of course 2bhp is worth your extra 7p a litre.

They were on a standard tune. And I would agree that for most cars and even "performance" cars on a standard tune 98/99 RON makes very little difference since the factory setup is for 95 RON fuel (as that is most prevalent and cheaper), however things change once you get into the world of performance tuning and mods....check the timing advances and fuelling using the OBDII to see how it is performing with different fuels

Tuned cars are a different kettle of fish. I used to run 99 ron on my old scooby as it was mapped for it. Standard car forget it. Well at least around the 200bhp mark a standard car with 500bhp may show better gains but i wouldnt know.

Even a normal car i would run super, it has a better detonation and burns cleaner and more efficiently.

There is a very sad case of arson going through the courts at the moment where a technical expert has given evidence that she was able to distinguish two different brands/types of petrol used in the arson.

Whether or not the differing fuels would make any difference in use in a car is not said of course, but it is clear from this evidence there IS a chemical difference between different fuels.

As others have said, there are plenty of treads on this and differences seem to be subjective.

The TFSI should be run on 98 anyway. 95 is supposed to be for emergency use only, althoguh I suspect plenty of people use it all the time. I always run my TSI on V-Power, as I did with my TFSI. As for making any noticeable difference, no it doesn't.

My car's un-modded but just feels 'Nicer' when I run it on higher octane fuel, I've also definetly seen MPG gains in the region of 5-10%, depending on the weather..

I'm running all 3 cars on ultimate at the moment, mainly because I get a 6p discount. I've noticed all 3 rum much smoother and the Scouts fuel consumption doesn't dip as much in winter.

Compared to the standard fuel ultimate contained more oxygenates to give a cleaner burn and improved additives.

I used to work in the fuel additives industry a few years ago and can vouch for the difference a good additive package makes. Mainly in maintaining clean injectors and deposit free inlet valves.

Ive only ever run my cars on Fuel saver (95 Ron) as i cant justify the extra cost of V-power. It costs me £60 to brim the tank and that only lasts about 10 days Thats over £2000 a year. Can't say i've ever had any problems (Touch wood) with using it. Mines mapped to stage 2 and pulls like a rocket

Fuelsave plus Millers.

Cheaper than VP and just as good.

What's the thoughts on the additives helping to clean the engine if you only use it once in a while? No, I'm not gonna go down the route of that apparent nonsense thingy that edd china used on tv.
