Seafoam vs STP motor treatment

[Run]

I have a can of seafoam and a can of stp treatment. Which one would work better as a fuel system cleaner? I just want to use these products up. On a side note I found seafoam to be very a effective cleaner of old gasket residue.

I would use each of them after an oil change. So two oil changes. Then go back to Techron.

Use them up at your next two fuel fillups

What are you trying to fix? If nothing and you literally just want to get rid of them, then either dump them in your tank or someone else's and forget about it.

Seafoam through brake booster hose. STP in tank I'd say.

Add the seafoam via vacuum brake booster hose as directed on the can.

Then see how your vehicle runs after...
