MORE than A Fuel Additive! 4+ is "21st Century Science with 3rd Generation Technology

"Importance of Super Concentrate" The Science

When fuel additives are blended, there is a process that takes place that means a lot to you in terms of value. The base products that do the work in a fuel additive are called 'Active Ingredients'. These are chemical substances that include things like:

How can you tell good from not so good?

Simple: In general terms the lighter colour, the more solvent and less active ingredients. this may not hold true when the main ingredient of the additive is alcohol derivative.

So why 4+ is for you? 

• Lower Treatment Cost- Because our products are so concentrated, they typically treat more fuel than others (just compare)
• High concentration levels mean that we are able to offer TRUE multi functional products in one container (for example, 4+ Premium contains 8 active ingredients and 4+ Arctic contains 9)
• Value for money- High concentration of active ingredients means that you are buying active ingredient not solvent.
• Reduced shipping costs- We don't have to ship as much product as the typical additive blender does, and we pass the savings on to you. 
• Environmental Responsibililty- Lower shipping costs = lower greenhouse gas emissions.
