Anyone can recommend any fuel saving product? Are they really useful? How do they work? Any benefits and disadvantages? Will it damage the engine, etc?

most impt saving is ur right leg.
next list is tested & proven by labs, not disputed by Federal Trade Commission
1/ engine oil 2/ increase tyre pressure up to 10% abv recommended pressure 3/ use less aircon 4/ try to use more highways but limit speed to ard 70kmh, trucks in front of u will help reduce air drags. but do not tailgate too close.
