Shell V-Power (also known as Shell V-Power Nitrogen Enriched in the United States and Canada and Shell V-Power Nitro+ in other countries) is the brand name given to Royal Dutch Shell's - aka Shell - enhanced high specification fuels for road motor vehicles.
Petrol or gasoline is assessed, categorised and sold by an octane rating. Generally, in most areas of the world, the Research Octane Number (RON) is used, but in North America, the Anti-Knock Index (AKI) is used. Conventional 'standard' "Premium Unleaded" petrol in the United Kingdom, Europe, South Asia and Australia has an octane rating of 95 RON, and in North America it is AKI/RdON/PON 91-93 (RON 96–98). However, higher octane "Super Unleaded" - often formulated with higher quality additives, is usually set at around 98 RON in mainland Europe; but this can vary by market. Most oil/petroleum companies now 'market' their own Super Unleaded petrols under a unique name - and the current name for Shell Super Unleaded fuel is "V-Power". Like most Super Unleaded petrols, V-Power also contains higher concentrations of detergents and other additives to help clean the engine and smooth its operation.
In the United Kingdom and Denmark (where Super Unleaded must be a minimum of 97 RON), V-Power has a rating of 99 RON (whereas V-Power's predecessor Shell Optimax was rated at 98 RON). There is one other 99 RON fuel available in the UK, namely Tesco MOMENTUM99.
In The Netherlands, V-Power has a 95 RON rating, although officials from Shell stated it is effective 97 RON, but classes are limited to 92 RON, 95 RON, 98 RON and 100 RON.
In Germany, all Shell stations offer two varieties of petrol V-Power: Super V-Power, rated at 95 RON, and V-Power Racing 100, rated at 100 RON.
In Greece, most Shell stations offer V-Power Racing, rated at 100 RON. That is also the only petrol type rated at 100 RON throughout the country.
In Australia, from October 2006, Shell and Coles Express re-branded Optimax to V-Power (98 RON). V-Power Racing, the ultra-high performance variant has a rating of 100 RON although Shell have decided to phase out V-Power Racing from 21 July to mid August 2008, instead recommending V-Power. The previously obtainable higher grade V-Power Racing which contained 5% ethanol to boost V-Power's octane rating to 100 RON has now been phased out by Shell due to a "changing market".
In the United States (U.S.), at around 2004, all U.S. Shell gas "Premium" was rebranded as "V-Power". In 2008, Shell in the U.S. launched the new Nitrogen-Enriched Shell V-Power.
In Canada, from June 2005, Shell Canada re-branded Optimax Gold to V-Power.
In Hong Kong, as there is no oil refinery plant located in Hong Kong, Gasoline was imported from Singapore, which is 98 RON. However, V-Power sold in gas stations rumored reach 107 RON (the highest native RON for consumer grade commercial petrol across worldwide). Such figure is not supported by actual test, nor is it confirmed by Shell and which is contradicted from a reading material for Legislators of Legislative Council.
In New Zealand, from 2007, Shell rebranded 95 Premium Unleaded as V-Power. It is still rated at 95 RON.
In Indonesia, from April 2013, Shell rebranded 95 Super Extra as V-Power with additional additives. While it is still rated at 95 RON, Shell increased their pricing which makes them more expensive than other competitors.
V-Power Diesel is Shell's version of an enhanced diesel fuel, similar, say to BPs 'Ultimate Diesel'. Like BP Ultimate Diesel, Shell V-Power Diesel is designed for modern compression-ignition diesel engines, to facilitate enhanced engine performance along with increased engine protection, for more consistent operation and engine longevity.
V-Power Diesel is a blend of regular petroleum-based diesel and synthetic diesel, created using gas to liquids (GTL), along with some extra additives designed to clean the injection system and improve injection pump and injector lubricity.
One characteristic of V-Power diesel is that it is a lot clearer and odourless than normal diesel, mainly due to the synthetic GTL component.
The fuel is slightly less dense than regular diesel so, per volume, the unit energy is actually lower than regular diesel. This is offset, as the fuel tends to ignite more readily (and thus has a higher cetane rating) than regular diesel, and a side benefit of this is that it tends to produce less soot during combustion.
Shell also markets a different "premium" diesel in Canada labeled V-Power, which they state "Is specially formulated for year-round Canadian weather conditions, with a cetane improver, a de-icer and a corrosion inhibitor." but Shell also states that V-Power diesel will typically have an increased cetane rating of 1 to 2 points over standard diesel, which meets Transport Canada's minimum mandated rating of 40. This Canadian V-Power diesel is dispensed from a dedicated pump that injects a measured amount of NEMO 2061 additive into the diesel supply shared with the other diesel pumps at the service station. As a result it contains no GTL components beyond those that may already exist in the shared diesel supply.
Effective June 1, 2012, Pilipinas Shell launches the new premium diesel fuel grade, Shell V-Power Nitro+ Diesel (formerly Shell V-Power Diesel in the  D.
Development in motorsports
Shell V-Power sponsors a team that participates in Formula One racing on fuels, especially it is a merge to fight with cheaper than USA oil(e.g. Rockefeller well-known barrel closing), Shell established technical agreement and cooperation (in fact sponsorship) with the Scuderia Ferrari, in 2013 with 60 years' anniversary.
Part of the campaign, especially targeted to sell "V-Power Nitro+" brand of the fuels (higher priced than usual and similar to blend used on the track) is organizing the "Formula One" events in cities without a track. For example, on the streets of Warsaw, Poland, where Scuderia Ferrari Felipe Massa drove the race car used in 2013 Formula One(in time gap before a Monaco race).
