I purchased a bottle of the 4oz oil additive for my wife's high mileage 4 cylinder Nissan Altima and poured the whole bottle into her engine. I immediately noticed a reduction in engine shake and a noticeable drop in engine noise as well. She says the car is more responsive and seems to want to go from stop (no hesitation as before). After 3 full tanks of gas she has recorded an increase of 5 miles per gallon, in the city!! I'm VERY impressed by the results and certainly will be buying more.. This product is legit.. I am invested in the company now that I know the products are real.. Go NTCH(soon to be minus the F)!!
So i put the n1 oil in the old truck. First day out no sluggishness no bog down when I stepped on the gas...boosted the engine up! 2nd day engine much quieter much much quieter. I will test gas mileage this week. But my old truck likes it! I bought four more today for tractor and golf cart and family car. It works!
