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?

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?

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.
I've filled up with Nitro+ a couple of times in my Box 986S now. No perceivable difference I'm afraid, either with performance (wasn't expecting any TBH), or fuel economy. I guess the long term benefits in terms of cleaning agents and anti-friction enhancement will be next to impossible to ascertain outside of a lab. I'll just have to console myself with knowing I'm putting the highest quality fuel available in my cars and this has to have benefit vs. using other petrol types... perhaps...
The said, the OBC in my turbo charged Audi does report an extra 15-20 miles range when filling up though.

Shell is claiming more power:
"In comparison to our previous Shell V-Power Unleaded, we have rebalanced the formulation to contain 25% more Friction Modification Technology (FMT).

Good spot! But I can't discern any difference either. So who is going to kick-off a class action law suit ;-)"In comparison to our previous Shell V-Power Unleaded, we have rebalanced the formulation to contain 25% more Friction Modification Technology (FMT).

So it seems Nitro+ creates a much more noticeable difference on forced induction engines. I get the reasons why a higher octane fuel will change the way in which the knock sensing functions, but surely this would be the same for both forced and naturally aspirated engines...? So why is the difference more perceivable on turbo and supercharged cars?
