you mean system g? if thats it then thats a fuel additive(cleaner) system g for petrol system d for diesel.
Ive used the system g its good but i like using additives from stp, chevron, bardhal, or sea foam.
if its not the same do tell me more of this system clean ill go get some, i maintain all my fuel fill ups at a bpcl pump.
gave my ac condenser(front coil) a wash with the garden hose, jeez the amount of mucky water that came out from that thing amazed me, will see if it did a trick when theres a sunny hot noon.
engine bay had some muck as well guess the radiator fan did its job in spreading it around, by the way I'm having this weird thing, after driving through some water say just reaching to the alloys and whenever i use the brakes after that abs
activates. another thing noticed when my driver side wiper reaches the top side of the windshield i get this glass kind of cracking noise, will try getting a video when theres rains.
