I buy the gal size to refill my small containers...its cheaper that way. ### ⭐⭐⭐⭐⭐ Still the best *by P***. on August 22, 2026* Works as it should, an absolute must have for older cars or marine engines. ### ⭐⭐⭐⭐⭐ Wow what an amazing product for RV generator *by A***H on August 9, 2024* My RV generator repairman recommended I use SeaFoam to perhaps get my seldom used RV generator (Onan 4000) to run smoother, I added a gallon of Sea Foam to my RV fuel tank and then added a full tank of gasoline. Drove about 10 minutes. Parked and started the generator. It ran rough so I let it run without a load for about 10 minutes and then turned the RV air conditioner on HI. Ran it for about an hour. It smoothed out! Turned off the air conditioner and let generator run without a load for another 10 minutes to “cool down” before shutting it off. My generator now runs very smoothly! And I am sure the Sea Foam will be improving my RV engine as well on our next camping trip. (My RV and generator share the same fuel tank) I am very impressed with the results and highly recommend Sea Foam. Sure it is expensive; but, cheaper than a trip to a mechanic. ## Frequently Bought Together - Sea Foam SF128 Motor Treatment, 1 Gallon - Lucas LUC10013 10013 Fuel Treatment - 1 Gallon - STA-BIL Storage Fuel Stabilizer | Keeps Fuel Fresh for 24 Months, Prevents Corrosion, Gasoline Treatment Fuel Additive that Protects Fuel System, Gas Stabilizer for Fuel Storage, 1 Gallon --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/4757099-sea-foam-sf128-motor-treatment-1-gallon](https://www.desertcart.us/products/4757099-sea-foam-sf128-motor-treatment-1-gallon) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-16*
