Shell V-Power Nitro+ : is it worth ?

A friend has seen 2-3 weeks ago in Norway a petrol called Shell V-Power Nitro+. Surprisingly it appeared in the last days in Slovakia. Shell websites (slovakian and norwegian) are stating the same, only a very vague, basic and marketing only information : it cleans the engine (additives ?), some Ferrari blah blah and it increases the engine performance.

About the octane number (RON in our case), they are very shy, they just compare it to the FuelSave stating, that Nitro+ is for performance and FuelSave is about fuel consumption.

I tanked a full tank (5 liters remained from the previous one). It's expensive like hell - 1.71 € / liter in Bratislava, Slovakia. I don't trust these fancy fuels but I was curious.

Results : 

Indeed, after 5 - 6 km I felt a bit increase of performance. Nothing dramatic, maybe even a
placebo effect, but subjectively the car goes quicker after the gas pedal. I remembered myself on the feeling after using 102 (ROZ = RON) at Aral in Germany. It's simillar.

Fuel consumption depends hardly on the drive style. So I've tried to drive the same distance, around 120 km, same conditions 50/50 city/outside (no highways) with the same a bit more sportier style than cruising, but no speeding. With the regular RON 95, the fuel consumption was 11.2 litres/100km. Nitro+ required 10.8 litres. Interesting.

So the situation is : subjective feeling of more power and decreased consumption. 

Is it really worth ? 

If a regular petrol 98 costs around 1.50 € these days, with the above consumptions, 100 km costs 16.8 € and the same ride on Nitro+ costs 18.5 €. That is 1.7 € or ~10% more on 100 km. So in my case the lower fuel consumption doesn't balance the price.

Let's believe, it really cleans the engine more than regular fuel. 

Is the fancy fuel really increasing the engine power ? I found a video regarding this :



The Subaru in the video is weaker than my Saab (275 hp), but it got 14 hp more. In the Subaru case it's 6% difference. In my Saab the 6% hp would be 16.5 hp more = 291.5 hp. (275 + 6%). Nice. And the 16 hp more are definitely to feel. Also it would indicate, that the fuel is at least RON 98 if not 100. But is it worth the money ?

As usual in these situations, some people don't care. I do. A price of 1.71 € / liter is  too much. It stays similar as with the RON 100 V-Power - when I go driving longer distances, I buy it. Otherwise rather not. And until the price difference doesn't drops, it stays so. C'mon Shell, the new stuff is fine, but too expensive for what it offers.

Note : maybe in other countries the Nitro+ is distributed under another name. Pricing can be different. Also, I will continue to measure it. If something significantly changes, it will appear here. 

Update : It's RON 100
