Hi John, thanks for the question! Adding Sea Foam when the tank is low works better to clean because the mix ratio is more concentrated. Then drive 20 to 50 miles before refueling to allow the stronger Sea Foam mixture to run through the system.

If you’re adding Sea Foam Motor Treatment to fuel for the purpose of cleaning (valves, carburetors, injectors, and chambers), adding more Sea Foam to a partial tank of fuel will offer a higher cleaning concentration than the same amount added to a full tank.

Please know that when cleaning a gasoline or diesel fuel system, it’s safe to add as much Sea Foam to fuel as you need.  For overcoming drivability problems caused by residues and deposits (hard starts, stalls, hesitation, loss of power), start by adding a full can of Sea Foam Motor Treatment to a partial tank of fuel. 2 oz per gallon is often a sufficient starting point for cleaning applications.

I only drive 200 miles a month. Nissan Altima with 125000 miles. How often should I put seafoam high mileage in gas tank?
