I saw a video from the Sea Foam official channel on YouTube that shows to add 2 whole cans to 1/8 of a tank, then spray 2 cans into air intake. It was also mentioned I should drive 20 miles… so just wondering if I should put the treatment in the fuel, then spray into the intake? Or drive the 20 miles and then spray into the intake? Also, is 2 cans of each excessive and could it do damage? I have a 20 gallon tank, so 1/8 of a tank is about 2.5 gallons. Does Sea Foam act as fuel when that much is put in? I’m just thinking I might not make it 20 miles on 2.5 gallons in my big v8 that isn’t getting good gas mileage.
Those are great questions, Joe! You must be referring to the video on how to pass an emissions test.
Hope this helps!
