Ford f150 with 4.2L engine and standard transmission
The truck has over 350 thousand miles on it and lost a lot of power, I used to get 475 miles per tank so I tried it the first thing I noticed was the power was back and the mileage is a lot better, people with high mileage engines should try this product and it's very inexpensive.
