I know how to do proper tests.
I have read a thread here on it.
Road tests are not the same as a scientific test however they can give a general idea whether or not something works.
I have seen many gas saving devices and claims. Most are B.S. but some have a logical base of science by which they MAY work. And occassionally some do.
I have heard many good claims with magnets but with test after test I have seen nothing for results.
I do not always go by what people say about something.
Most of the time it is best to test an idea for yourself to see the results.
Do any of you recall when special pills were being sold that claimed it would boost fuel mileage?
Well, I had to give them a test. I have 3 different vehicles and believe it or not and as much as I hate to admit it, those pills did help the fuel economy in one of them. In fact after testing them repeatedly in my Chrysler Town & Country I got an average of 4mpg better. But in my Aspire and Chevy truck there was absolutely no difference at all.
I keep a constant log book of my fuel mileage in my vehicles so I can keep constant track of any changes.
