Seafoam has large amount of isopropyl alcohol, very last thing you want to be putting into your fuel-system. Similar to ethanol crap in modern gas that absorbs water, causes separation and tonne of corrosion and clogging issues. Seafoam is snake-oil and proof that marketing works.
Instead, use PEA-based fuel-system cleaner. Works much, much better than Seafoam for cleaning:
- Red Line SI-1
- Techron Concentrate Plus
- 3M Max Strength Fuel System Cleaner #08814
- Royal Purple Max Atomizer 18000
- Gumout All-in-One (might be off list soon due to lowering amounts of PEA)
