128 oz seafoam motor gas treatment
I'm a big fan of seafoam which is used to treat a tank of gas to clean out your engine parts. This container of seafoam was nice because it was bigger than I can find at my auto parts store. I was able to get this delivered to my house. The container is made of metal and the plastic lid keeps it from spilling. The directions on the back are easy to read. I used a plastic measuring cup to get the correct amount to put in my gas tank. I would recommend this product to anyone who drives a motor vehicle.

There is just something about the look!
Engine additives have always been one of those things I've never been sure about. Especially when 16 fl oz are $10.99 at most retails places. But Sea Foam is highly regarded and rated so I've given it a try a few times. I replaced my valve cover gasket on my Acura a couple years back, and was shocked by the caramelization of the case. So I knew I needed something to clear it up.Long story short, I tried out Sea Foam, and it seemed to help. But my review isn't for Sea Foam, it's more for this can and deal.$5*.** for 128 oz of Sea Foam is a great deal. Plus, there is just something about the look of the old oil can, that just makes me want to work on my car all day. The utilitarian style or vintage dare I say. This is a real bang for your buck type of deal, and I recommend to anyone on the fence.Some folks have complained about packaging, I had zero issues with mine. It was in pristine shape. It's Amazon, just return it and send it back if it comes damaged.My only con is the pouring gets a bit messy at first, because there isn't an air hole to stop the *glug glug glug* onto your driveway. Get a long funnel, and you'll make out just fine.5 out of 5

Wow what an amazing product for RV generator
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.

A friend told me this was good stuff. It is actually G R E A T stuff.
I was having a LOT of trouble getting the Onan 4000 generator running in the used 2007 Thor 23FS trailer that we purchased. Seafoam worked to clean out the carb and get to the point where the generator would start. I had checked the oil level, replaced the fuel filter and it still would not start. Using Seafoam to clean out the fuel line worked.I recommend disconnecting the fuel line from the carb, draining the carb and the upper end of the fuel line, fill the fuel line with Seafoam, then prime the Onan (which will pump the Seafoam into the carb) and let it sit for an hour. Then try to start. I repeated this three times and then the Onan would start for me.It would not continue to run, but that was due to the choke adjustment being WAY out of adjustment. Now the Onan starts with the remote switch like it is supposed to without even going outside.
