Shell V-Power Nitro+
Discussion
Anyone used the new Shell V-Power Nitro+ unleaded yet? Is there a noticeable difference in responsiveness over using the standard V-Power stuff?
One thing caught my attention in the email blurb sent by Shell:
"In comparison to our previous Shell V-Power Unleaded, we have rebalanced the formulation to contain 25% more Friction Modification Technology (FMT). This technology has been tested with Ferrari as part of our long standing technical partnership, and is designed to instantly reduce friction in critical engine areas and thereby help the engine to deliver more power to the wheels.
Protecting Cylinder Walls – Our Friction Modification Technology is designed to instantly reduce friction between the piston assembly and cylinder wall by coating them with a protective film."
I assume less friction equals less heat. Would this in turn reduce the risk or likelihood of bore scoring in Porsche engines?

Do people understand oil companies? All fuel regardless of the seller is refined at a local refinery by who ever happens to own it, and shipped to the local tank farm of the particuler oil company who will label it and sell it, at that point they add the additives they want, do you really think that they have an addative that can significantly reduce friction any more than the 'snake oil' they sell at your local motor factors. Ocatane value in V Power is different 97 will give more power than 95, try using 105 Avgas and a remap, 107 adds 40BHP to my GTR engine compared to 97.
I will not use V power because if the car is left then when the benzine evaporates of it leaves all the additives behind in the fuel system and blocks all sorts of things, not such a big problem in the fuel injected Porsche but a huge problem on the webbers that are fitted to my 7s, Try leaving a little V power in a saucser and let it evaporate off and see what it leaves behind, may not be a true test but I avoid V power when ever I can.

Speculating here but I would reckon that the P cars that are more fuel sensitive, such as the Turbo, would benefit more.
You would need to run the car on this fuel for a few tanks and then do some measurements.
Evo have done this type of comparison test in the past, against different fuels, lets wait and see.
Aside from the general debate about V-Power vs. other high octane petrols, I'm still curious about this supposedly new "Friction Modification Technology (FMT)" additive. From what I understand, the cause of bore scoring in the Porsche flat six is to do with the sudden temperature changes than can be experienced as the engine is thrashed, then idled, then thrashed again, i.e. the water cooling system can't regulate the temperature change fast enough.
My theory here is that less friction generated between pistons and cylinders should generate less heat. Just interested in whether others think there is any merit to this? If so, and assuming this Nitro+ stuff does what it says on the tin, then it should (in theory) reduce the likelihood of bore scoring.
I guess there is no sure fire way of testing this, but is my theory sound?

I am guessing that engines with bore scoring issues do not have oil squirters? They are there for this very reason - to moderate oil temperatures in and around the pistons.My theory here is that less friction generated between pistons and cylinders should generate less heat.

Whereas that is true for most (regular) fuels, I think you'll find that all V-Power comes from the Stanlow refinery.ETA: just noticed that Rigster already pointed that out...

True. Although Stanlow hasn't been owned by Shell for a couple of years now. Should still be manufactured to Shell's standards though as it will be produced under a licencing agreement.ETA: just noticed that Rigster already pointed that out...

Just filled up with this stuff.
Can't feel any difference yet.......
So, I'm curious - has this replaced normal V Power? If so, it's a bit odd that it was only announced yesterday yet from what I can tell from this thread all the stations seem to have used up their standard Vpower stocks and replenished their holding tanks with Nitro+ so quickly.Can't feel any difference yet.......
Either that or they've just changed the name, or the new stuff's been in there for a while until the launch

Apparently it has been deliver for a while .... I suspect somebody just dumps the additive in the holding tank at somepoint ...but it reality whos knows ...
I feel it is missleading to use the word Nitro .. it contains none ...(you can't mix Nitromethane with petrol)
That's interesting. I've used a tank of what I thought was the older non-nitro+ petrol in my Audi 2.0TFSi this week. I did notice that I managed 395 miles out of a tank full, whereas I can usually only squeeze 370m tops, and I haven't been driving particularly differently in terms of lead footedness. I wonder if the newer stuff has been in use for some time. I feel it is missleading to use the word Nitro .. it contains none ...(you can't mix Nitromethane with petrol)
Still have 1/4 tank left in my Boxster from when I filled up a fortnight ago. Will fill up this weekend, although like others have posted, I'm not expecting to notice any difference in a normally aspirated car.
When I read the marketing info it seemed to say it just has more friction modifier and cleaning additive. No mention of RON so I assume still 99 per v-power. Bought some for the Skyline but only because it's 99 RON and I get the money off vouchers with the points. (not much but offsets the cost a tiny bit)
