Yes, Sea Foam works very well in high mileage trucks. Sea Foam cleans residues and deposits that commonly contribute to performance issues like rough idle, loss of power, etc.

I’d use High Mileage, which is formulated to clean heavy residues and deposits after years of buildup (it’s strong!). Wait until you have a low tank of fuel (1/8 of a tank or so). Add a full can of Sea Foam High Mileage and drive it until almost empty before refueling. The high concentration will do a great job cleaning.
