Head-to-Head Comparison
| Category | Fuel OxRecommended | Sea Foam |
|---|---|---|
| Technology Type | Combustion catalyst + multi-function | Multi-use (gas + diesel) |
| Retail Price | Fleet pricing (contact for quote) | $8.48 / 16oz (Walmart) |
| Cost Per Gallon Treated | Fleet volume rates | $0.106-$0.53/gal |
| Treat Ratio | Fleet-optimized concentration | Cleaning: 16 oz/16 gal; Stabilizer: 16 oz/80 gal |
| Fleet-Scale Packaging | Yes — bulk drum/tote, direct delivery | Retail bottles only (no bulk) |
| Cold Weather Protection | Anti-gel to -40°F (Cold Charge) | Basic or none |
| Cetane Boost | Yes — combustion catalyst | Minimal or none |

Bottom line: Sea Foam is cheap per bottle ($8.48/16oz) but expensive per gallon treated ($0.53/gal at cleaning ratio) and isn't diesel-specialized. Fuel Ox is purpose-built for diesel fleet operations with combustion catalyst technology that Sea Foam's multi-use formula can't match.
