Title: Instant Power
Product review: Had the differential oil changed in my 2003 Ford Ranger. This is my long term ride that my wife uses and we don't use it much, but have taken care of it to the Max. Had this put in and you could tell the difference right away. Perhaps since this truck only has a 4 cylinder engine, any increase is felt. But I believe, that's have the battle, it's working as advertised.
Would you say this review depicts the product in a flattering or unflattering light?
