WOW bro thats a lot of MPG's man. I got an extra 4 MPG going to and from Uwharrie which is about 64 miles one way. At my best MPG before seafoam (13MPG) I spent 9.8 gallons round trip. After seafoam I spent 7.3 gallons round trip Saving me 2.5 gallons of gas at $4.00 a gallon thats $10 in savings $10 for seafoam so my first trip the stuff paid for its self if I did this math correct???????? I'm still at 16MPG so I'm still running 3MPG better so saving money every time I drive it now.
