Gas saver makes my cars get 7~10 miles extra on driving range for next to NOTHING!!!

Hello:

I just discovered the new way for our small tank cng cars to have little more driving range, maybe that's all you need to roll it to the CNG station without calling the tow truck! I tried it on my car and the MPG improved from 33~34mpg to 36~37mpg by installing a simple adaptor, it's just couple dollars and will save us some money and gives longer range, give it a try, I got it on the ebay:

The device shown would slow down the O2 sensor signal. This is different to the seller's statement, which states that it will bias O2 rich and then trim your mixture lean. I have not had any gains with slow O2 sensors. Fuel economy is generally better when O2 crosscounts are high (high lean to rich and back switching) They (these devices) usually help when throttle is initially opened by not trimming mixture to richer signal right away, but they will cause your pcm to run richer at the begining of the cruise, which robs your gains. If the engine is ran too lean, it's longevity is shortened. I know it's cheap, but I do not know if I would bother.
