I don't drive a lot of mileage so have not noticed a big change yet but have not seen any bad effects. Works good.
Mark Webb, California
Uphill acceleration has definitely improved. I'm getting 2 mpg more in my commute at regular cruising speeds (2014 Toyota Yaris).
Doug Powell, Kissimmee, Florida
My car has better gas mileage and more power in the engine. When you're at a full stop and step on the gas, the car just takes off and you here the air going into the engine like a race car.
