Fuel additives can play an important part in maximising the performance of your engine, in addition to keeping it operating reliably and efficiently.  We favour the products from Klotz and Silkolene.  Both are giants in their field and enable us to offer solutions to suit every budget. 

If you're not sure what you need or why you need it then here some useful tips:

Q: What are Octane Boosters? (fuel additives)

A: Octant boosters generally split into four categories. Power adders, fuel system cleaners, all-in-ones and then those that don't really do anything (junk!)

Q: Which Octane Booster should I use?

A:  This will be dependent on your needs and your budget.  The Klotz Higher Octane Booster is a superb all-in-one product that can not only add significant octane, but also clean your fuel system and preserve fuel for long periods of time.  This is suitable for use with petrol and ethanol fuels.   

If you're after a lower-cost fuel system treatment to use on a regular basis, then the Silkolene One Shot FST offers a credible alternative to Redex.
