pardon me if there is a similar thread discussing this...

I installed a gas saving device (it comes in a chrome cylindrical casing) that supposedly will make my truck ('99 4WD Frontier) more efficient (more kms/liter, increase in power, less emissions, etc.) and so far, it seems to be working...

I've been browsing through several threads about Khaos and its effects on the engine and since the device I have (I think its called GASSAVES) supposedly works the same way does it follow that it will have the same effect on my engine?

May mga gumagamit ba sa inyo ng device na 'to? Kamusta naman epekto sa mga sasakyan nyo?
