BP Ultimate Unleaded

BP Ultimate Unleaded removes an average 95% of existing harmful deposits that stop your engine working as efficiently as it should - and keeps it clean too. Your engine efficiency is improved even more by our special friction-reducing formula.

BP has long been acknowledged for its fuels technology expertise. Put BP in your tank and you're getting quality developed through a comprehensive development and testing programme. 

Our BP fuels are a way of caring for your engine on the inside. Unlike some fuels, BP fuels won't leave harmful deposits in your engine. In fact, they are specially formulated with advanced cleaning properties to help keep critical engine components clean and protect against further deposits forming. 

This helps to keep your engine fitter and healthier, maintaining its performance and fuel efficiency.  

And our petrol helps reduce friction inside the engine, contributing to enhanced efficiency and performance. 

BP fuels. Quality you can trust.

5 Reasons to use BP Ultimate Unleaded

BP Ultimate Unleaded is specially designed to keep your petrol engine fit and healthy and running efficiently. As well as protecting against the formation of deposits, BP Ultimate Unleaded is also formulated to protect against wear in key engine components and guard against the harmful effects of corrosion. Plus it contains a special formula designed to lower the friction in your engine.

Cleans

How BP Ultimate Unleaded cleans your engine

The images show an intake valve from a petrol engine before and after running on BP Ultimate Unleaded. As you can clearly see, the valve on the left is heavily coated with black carbon deposits as a result of the engine running continuously on ordinary unleaded petrol. On the right, is the same valve now virtually as clean as new after the engine was switched to BP Ultimate Unleaded and run for 10,000 kilometres.
Overall, BP Ultimate Unleaded’s remarkable cleaning ability removes an average 95% - and up to 98% - of the existing harmful deposits that stop your engine working as it should.

Protects

How BP Ultimate Unleaded protects your engine

As well as protecting against rust, BP Ultimate Unleaded is designed to reduce friction in the engine.

Its special friction-reducing formula provides a protective coating on the upper cylinder walls, helping to reduce friction between the piston rings and cylinder walls.

Additionally, the friction reducing components in BP Ultimate Unleaded build up in your engine lubricant over time, helping to improve the properties of your lubricant as well.

Reducing engine friction means that less energy is lost, so more of the fuel energy can be converted to useful mechanical output, contributing to better fuel economy and improved performance.

Efficient

How BP Ultimate Unleaded increases efficiency

BP Ultimate Unleaded has been designed to increase your engine’s efficiency and give you more miles per tank in three very important ways.

First, the basic business of combustion: BP’s best petrol fundamentally burns better than ordinary fuels, which means the process of combustion is more efficient and so less energy is wasted.

Second, our advanced fuel formulation includes very special friction reducing components. These help to reduce friction between the piston rings and cylinder walls, meaning that less energy is lost.

And thirdly, BP Ultimate Unleaded cleans your engine as you drive along, ensuring that vital parts like valves and injectors don’t become clogged up with harmful deposits.

Performs

How BP Ultimate Unleaded increases performance

A combination of high octane, powerful engine cleaning and reduced friction means that BP Ultimate Unleaded can make it feel like you’re driving with a bigger engine.

Octane is a measure of petrol’s combustion quality. If pockets of fuel and air explode ahead of the flame, this is called knock. The modern engine management system deals with this by de-tuning the engine to protect it from damage, but this reduces power output.

With its higher octane quality of 97 RON minimum BP Ultimate Unleaded burns better than ordinary petrol, and protects the engine from knock. By burning more smoothly and completely, it releases energy more efficiently, leading to enhanced engine performance with better fuel economy and less emissions.

Reduces

How BP Ultimate Unleaded reduces exhaust emissions

Only a clean engine with the correct fuel and air flow can provide optimised combustion.

With its advanced engine cleaning formulation, BP Ultimate Unleaded can remove an average 95% of deposits that build up on critical engine components, and can prevent new ones from forming.

A clean engine is a more efficient engine, which in turn produces fewer emissions. And tests in a range of vehicles confirm that using BP Ultimate Unleaded instead of ordinary petrol can significantly reduce the harmful emissions from your car’s exhaust.

What's in it?

BP Ultimate Unleaded is an advanced high octane fuel. Its unique formulation contains a number of ingredients, each of which has been designed to perform a special task to help deliver the benefits of the fuel.

Deposit Cleaner

Breaks down and cleans away existing deposits on critical engine components such as intake valves and fuel injectors, enabling better flow into the engine and maintaining the quality of the fuel spray. Protects against the formation of new deposits, keeping new engines clean.

Friction Reducer

Provides a protective coating on the upper cylinder walls, helping to reduce frictionbetween the piston rings and cylinder walls.

Corrosion Inhibitor

Protects the engine and vital parts of the fuel system - including the fuel rail, fuel pump and tank - from rust and wear & tear.
