It was great to get this at a great price (on sale). For vehicles that have been sitting or driven seldom it works to clear out the carbs. Good for preventive maintenance too and for winter storage. It can only do so much (it doesn't do miracles)but is my first line of defence against clogged carbs.Helpd FI too.

I just started using Seafoam in my engine oil and noticed a big difference during the initial treatment. I also noticed a significant improvement in gas mileage (74,000 miles on it when i started seafoam) after doing the gas treatment, in my truck since day 1 of my new truck purchase (I've never had better then 17.5 MPG and now I get almost 19 MPG).

The product works well, but the container is horrible. I tried both the small bottles and this large gallon container. The small bottles are just a lot easier to handle. With the large gallon container... I end up spilling 1/2 on the ground or the side of my vehicle and the other 1/2 some how manages to get where it needs to go.

I contacted seafoam and I have been told that they are re-designing the container in 6 months and we should see a new container in stores by the end of 2012.

The container also doesn't have a tamper proof seal on the top, so anyone can spill or steal some of the product in the store (hopefully that will be addressed in the new container design for the end of 2012)?

In short
* Great product
* Poor container

Recomendation:
* Made a difference for me (I would buy seafoam again)
* I would never buy the 1 gallon container, just stick with the small bottles of seafoam.

        Comments about Sea Foam Motor Treatment for Gas and Diesel Engines (128 fl. oz.):

        I have been using Seafoam for over ten years. Living in Florida I like to keep a lot of gas in reserve for generators, hurricanes etc. I usually have at least 25 gallons on standby. Since we haven't had a significant power outage for a long time I have been using the gas in mowers, chain saws etc. I am using gas today that I bought over a year ago (I know because I write the date purchased on a piece of masking tape that I attach to the container). For long term storage I add 1 ounce per gallon. When I mix oil in the gas for small engines I add 2 oz per gallon. Recreational (no Ethanol added) is also recommended.

            A:

            Hi Poncho, with reference to your inquiry on the Sea Foam Motor Treatment for Gas and Diesel Engines (128 fl. oz.) - part# SF-128, for two-cycle engines prepare your normal gasoline/oil fuel mix. Add 2 oz. of Seafoam per each gallon of fuel and for four-cycle engines, add 1 oz. of Seafoam per gallon of fuel to the fuel tank. It is best to do this when the fuel tank is nearly empty to ensure you get the proper Seafoam/fuel ratio. The Seafoam will dissolve residue in the fuel lines and carburetor jets. For any further assistance, please feel free to call us at: 1-877-238-2623 or visit the nearest Advance Auto Parts store and one of our Parts Pros will gladly assist you with any questions or concerns you may have.
