Hi there. I just heard about a device that fits on the OBD2 port of most cars made after 1996. Its called Fuel Save Pro. Its supposed to improve gas mileage by up to 35% by reconfiguring certain setting to optimise fuel consumption. Has anyone heard of this device or know if it works? Can attaching something to that port damage the car in any way? I checked several review sites but they all seem to be promoting it rather than giving an objective review. Thanks for your thoughts. Cheers!

 

Don’t fail for false advertising. I don’t think there is anything can help you save gas except your driving habits and prompt maintenance of your SC.

 

Snake oil…if it really worked, everyone would be using it.

I remember when I heard about water injection and told my dad about it years ago…he chuckled a little and told me how it was nothing new and had been around for years…and it didn’t work.
He was correct.

back before my days in the USAF, they used water injection on the jet engines and it worked.
