How to use this Guide
If you are considering investing in a fuel saving device, your evaluation should be a three step
process. This Guide is designed to give you advice at each stage:
STEP 1 Firstly, consider whether this is likely to be the most cost-effective way for you to
save fuel in your vehicles – see Section 2.
STEP 2 If you decide a product is worth investigating, try to understand how it is
likely to work and whether its claims for fuel saving can be trusted – see Section 3.
STEP 3 Still want to go ahead? Then think about how you’re going to test the product on
your vehicles – see Section 4.
