Testimonials versus Controlled Scientific Tests

 

        We have had many testimonial reports from customers like many of our competitors have, praising the benefits of our system.  But I give absolutely no credence to a testimonial until I have verified the protocol used by the customer to calculate his mileage.  Examples of absolutely absurd protocols include the following examples. 

        A customer calls or emails a report saying that he is getting some great increase in mileage and I ask him, “How do you know?”  He says he’s been getting 20 mpg consistently for the last 6 months and now that he installed some device he takes a 100 mile test drive and he achieved 50% better mileage.  Certainly a 100 mile test run should be long enough to be able to calculate mileage accurately, and certainly a 6 month history must be fairly accurate, so what’s the problem?   The problem in this case is that the customer is comparing his normal city and short trip baseline mileage with his 100 mile trip highway mileage.  Or worse yet his 100 mile trip was not at highway speed but was on a back road with no traffic and done at 45-50 mph, typically the conditions for the best mileage you can get.  So city driving averaged 20 mpg and the trip test gave 30 mpg.  That does NOT mean there was a 50% increase in mileage using the device.

        Another customer says “I have a Scangauge and don’t have to do any calculation, and I got a 50% decrease in mileage.”  This customer gets 30 mpg while going down the road at 70 mph on the way to town.  While in town he fills up with gas, installs a device and then goes home on the same road, at the same speed, using the same Scangauge and gets 20 mpg.  Wow, I’m bummed, until I start asking questions.  Where did you do this test?  Ah, Ithaca, New York?  Isn’t Ithaca in a big valley and all roads leading to Ithaca go down hill, by about 2000 feet?  Okay, you get the picture.

        The next customer does the same test described above but on a flat road in both directions.  But the wind was blowing that day, tailwind on the way to town and headwind on the way home.  Or it was a cold day and town was only 10 miles from home.  The engine was real cold during the trip to town but the engine was warmed up before coming back home, big difference.

        The next customer calls in, all excited about a 50% increase in mileage.  “Wow, I normally get 300 miles to the tank and I installed this miracle device and I drove 100 miles and the gas gauge needle was not even down to the full mark.  I bet I’ll get 600 miles on this tank full.”  I don’t think so, you nit wit.

        Okay, so much for examples.  Here is a real report.  “We installed your model 12 hydrogen generator on our Chevy Silverado pickup and went from 16 mpg to 44 mpg.”  Really?  Says who?  “Well we filled up the truck and drove 100 miles and filled up again and it only took 2.3 gallons to fill it back up.”  Really?  Where did you fill up?  “What difference does that make?”  Did you fill up in the same town?  Same station?  Same pump?  Same exact position?  “No.”  Okay then you didn’t get 44 mpg and I certainly cannot publish that testimonial, except in an article explaining what is wrong with your mileage test.  This article.

        So how can a customer calculate mileage?  Well, the longer the test drive the better, and filling up in the exact same spot, at the same temperature, to the tippy top of the filler pipe, would minimize the inaccuracies.  Or if you have a Scangauge you can follow the procedure shown in the video seen by clicking here.

        So the next time you read testimonials on any other web site advertising a mileage enhancement device, please be suspect.  Know that we will not publish a testimonial without verifying a good protocol.  This testimonial of 44 mpg (a 175% increase in mileage) with our cheapest hydrogen generator, though at first seemed like a good protocol is also among the unreliable results reported with pride on many competitors’ web sites.  Not here.
