Dont seem any different to me

I topped up with it today!

Sounds to me like Shell have declared war on octane boosters.
If you buy this Nitro+ stuff then you won't be needing this:

http://www.asptrading.co.uk/acatalog...E_BOOSTER.html

I read a review by one of the online car 'magazines' and it came out top, adding about 2 RON (not the 6 quoted by this trader).
The Aussie manufacturers have a website of course.

One of the claims is that it provides added valve seat protection.

Once I've got my Type 20 Hawkeye (this coming week) I'll run 'unadded' until top-up time then see what happens with this stuff.
Apparently 1ml/litre of fuel is enough to make a difference, so at the price I bought it's about an extra £2 per fill-up (equal to 4p/litre).

The main reason I bought it was just in case I have to put 95 Octane in.
You can lob up to 15ml/litre of this stuff in apparently, so the 95 would easily be raised to 97+.

I'm cynical about oil companies.
I bet it won't be long before the masses are made to pay a premium for nitro+.

No difference, octane rating is the same, for those saying 25% less fri ruin read the bumf again.. It says 25% more friction modifier added to the fuel.. That could make 0.1% of no difference in actual friction in the engine for all we know. Marketing hype and placibo effect at its best.

djr

we have it in carlisle the guy working there told me "you can feel the difference straight away" had 2 tanks so far car feels the same to be honest

25% less friction on what?? Fuel pump? Fuel lines? Injectors? or money out of wallet

I haven,t noticed any difference . Steve.

I remember getting a roasting off my fleet manager for filling up with diesel Ultra years ago. He said it has no economical or performance advantages and is a gimmick to get more money out of suckers like me.

Lol....
Ive had that roasting too mate.....

I had my Sunday morning spirited drive today and have to say that at certain overtaking spots and contrary to what I said before, it felt quicker lower down. I wasnt looking for improved performance and to be honest forgot that I put this super dooper nitro turbo nutter fuel in earlier this week but I have to say I am a firm believer that this is more than just a gimmick.

I'm well into my third tank now and I reckon I have better pick through the gears at lower revs

waldmanbrown

Did anyone get there free shell v-power pen?

SRSport

What free pen?

waldmanbrown

went and filled up friday and received a nice red pen saying V-power on the side when paying. Mmmm lucky me

mrmadcap

What you are experiencing is the placebo effect.

I agree with the last few posts. I can also feel a gain in something. Can't put my finger on it but overtaking and coming out of corners is special at the moment.
Free pen??? I want mine.

SRSport

A placebo is a result of a fake stimuli. I didnt drive this morning with any thought about petrol. My wife was next to me and as I overtook a car I turned to her commenting how that seemed easer than usual.

Anyway what makes you so sure its a placebo anyway? I have been there and done that with a KN filter many moons ago, trying to make myself believe that there was somehow some extra magic ponies in there. I would have said I was now more sceptical about such claims than most as I am more than aware of wool that manufacturers try and pull over unsuspecting people's eyes.

Lets see some actual proof me thinks. Some dyno runs etc, im sure some of the big tuners on here have the ability to do some tests.
If this new nitro stuff improves performance/power I'll be utterly amazed. I really don't believe that the difference (if any) is even minutely noticeable. You 'want' it to be better so you end up believing it is. Ask your mrs to go fill the car up next time with a 99 ron fuel of her choice (she's pretty limited on choice I know) and see if you can tell which fuel she used.

chopperman

i'm with you on this. I dont think there would be enough performance difference that it would be noticeable. I think if it did make any difference it would probably show up in the mpg rather than bhp. You may get a couple of miles extra out of a tank at best. The power of our cars goes up and down depending on temperature and weather anyway, so feeling an extra bhp or two on a 300bhp+ car would be impossable and even if you could you couldn't honestly put it down to this fuel. Could of been a colder day or even a road surface with less friction making it feel quicker. I think you would need at least 10 bhp to feel it and i doubt this petrol will give that.

SRSport

I really think that I have addressed this.

The mention about the weather is much more plausible in attributing a difference in 'feel'. There are many factors though, tyre pressure could be another, maybe they were slightly lower pressure so the car felt smoother. With me I initially felt something I wasnt expecting only to later find out that it was what I should have felt, which makes it pretty convincing. Today I wasnt looking for anything and felt a difference in the power delivery. This was the first time I had really put my foot down since filling up and in my opinion, is similar to doing a blind test with petrol only it was a blind test as to what I was expecting.

SRSport

Do you not think that 10bhp could be gained from switching from Sainsburys 97 to the Nitro 99?

I would also be interested in finding out whether certain engines respond differently. I remember the 5th gear test where the Japanese STI benefited a lot more than the Golf GTI. Mine is a Mercedes 2.0 Turbo so I wonder if this responds differently to the Imprezas on here or is it purely to do with state of tune?

chopperman

If your car is better suited to 99ron than 97ron you could quite possibly gain 10bhp or more using the 99 over the 97. It would depend on how much timing your ecu pulled back while on the 97. If you put 99ron in a car that's designed to run on 95ron i doubt you would notice any difference.

I'm not saying this new petrol doesn't give you more. I cant say because i'm yet to try it. I just can't see how it does. Its the same 99ron as normal v-power but with added anti friction additive. I would like to think the very expensive fully synthetic oil i use does that anyway .

High pressure, cold weather or advertising?

Shaun

Not sure of the relevance of that question/statement. At it's basic level you're talking about two different octane rated fuels. Both VP and VP Nitro+ are the same octane rating.

blackhawksti

I've seen an increase in mpg since going from V-Power to the new Nitro V-Power. I don't know whether I've been driving even slower than my normal grandad pace, but nevertheless I had nearly 26mpg off my last tank. I've never had that figure since running the engine in with no turbo.......

SRSport

Ive not paid attention to the MPG so Ill have to take a look over my next couple of commutes.

LuckyWelshchap

When Optimax arrived in these parts I saved up for the extra £2.50 it cost to fill the tank of my Mondeo and it actually went from around 28mpg commuting to about 31 I think.
I certainly had a greater percentage increase in mpg than cost of filling up.

I'd saved the extra cost of the second fill-up by having an extra day's commuting out of the first one.

Mind you, the same wasn't true about the 1.2 Nova that replaced it.
I don't think there was any difference at all.

smc ste

im paying 138.9 a litre at Coleshill bham on the dual carriageway. run it since the day it came out. my engine seems to run a lot smoother and mpg has increased. I have a 50 mile commute a day and have deffo noticed the difference. btw was the old shell vpower 98 RON and the new nitro is 99 RON?

smc ste

Interesting results not good for BP ultimate. old v power came out on top.

LuckyWelshchap

One thing I've noticed is big variation in the difference between ordinary unleaded and Nitro+.

Just off J18 of the M4 (I think - it's the Bath turn-off) ordinary is 1.39 and Nitro+ 1.53 - 14p/litre more.

My nearest (Crumlin on the A467) the prices are 1.33 and 1.395, only 6.5/litre more.
