## Questions & Answers

**Q: This item (Sea Foam Motor Tune-Up) oil additives? Or fuel additives?**
A: seafoam is mainly a fuel system cleaner and it does work well. as for your oil, it acts as a cleaner also, targeting sticky valves, dirty port holes , dirty lifter issues etc

**Q: how does it do in motor oil**
A: I just used Sea Foam in my oil for the first time. I have a 50 year old car with its original, never-rebuilt motor. The lifters have been tapping for awhile so I thought it was worth a try. I added Sea Foam to the crankcase oil according to the directions (1.5 oz. per quart of oil). I let the motor run for about 15 minutes. The lifter noise went away almost immediately. Afterwards, I changed the oil as normal. When I drained the old oil, it was noticeably thinner due to the presence of the Sea Foam. I added new oil and filter, and the engine runs like a top now. No more noise. This stuff is great.

**Q: I can run Sea Foam in the crankcase along with my oil at all times or just as a cleaner prior to changing the oil.**
A: If you read the bottle, the amount you use in your crankcase is a very small amount, it is not intended to replace the OIL, it just helps it work better and loosen up deposits, DO NOT PIT A WHOLE BOTTLE OF THIS IN YOUR CRANCKCASE, read all directions

**Q: I used one can for a 16-gallon fuel tank of my car, which will impact the engine?**
A: Motor Treatment mix amounts for two-cycle and four-cycle gasoline engines, diesel engines, and rotary (Wankel) enginesThe recommended concentration of Sea Foam Motor Treatment varies depending on the type of fuel and type of engine. Please consult the table below: Type of Fuel Recommended Average Mixture Comments Normal gasoline grades (including 10% and 15% ethanol blends) 1 oz. Sea Foam Motor Treatment per gallon of gasoline Can mix up to 2 oz. per gallon of gasoline if necessary. Mixing at less than two-thirds oz. per gallon will impair the effectiveness of Sea Foam Motor Treatment. Diesel fuel (including low-sulfur and ultra-low-sulfur blends) 1 oz. Sea Foam Motor Treatment per gallon of diesel fuel Can mix up to 2 oz. per gallon of fuel if necessary. Mixing at less than two-thirds oz. per gallon will impair the effectiveness of Sea Foam Motor Treatment. For factory-designed E-85 fuel engines 2 oz. Sea Foam Motor Treatment per gallon of gasoline  two-cycle, gas/oil mix fuel engines 2 oz. Sea Foam Motor Treatment per gallon of gasoline  Sea Foam Motor Treatment is blended oil, and will not run a gasoline, gas/oil mix or ethanol engine without introducing hydrocarbons (gasoline / ethanol) to the mixture at a minimum of 50% concentration. On the other hand, a diesel engine will run for a short time on 100% Sea Foam Motor Treatment.Special note for oil-injected engines: Sea Foam Motor Treatment is only added to the fuel in the above recommended concentrations. Do not pour Sea Foam Motor Treatment into the oil reserve tank for oil injection!Fuel injector cleaning machines in a controlled environment use Sea Foam Motor Treatment as their safe cleaning agent, mixed with gasoline or ethanol blend at a 50/50 ratio of fuel to Sea Foam.Read more about Sea Foam Motor Treatment- See more at: http://seafoamsales.com/recommended-mix-amounts/#sthash.O27OpPQY.dpuf

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product does what it says it does.
*by G***. on April 23, 2016*

I somewhat recently bought a 1983 Volkswagen Vanagon With the 2,0 litre aircooled engine. I went to clean the ERG valve recently and found that it was clogged all the way with just greasy sooty gunk from the exhaust so im guessing my car has not had much of a cleanout ever and the erg filter is likely rusted out but nonetheless I knew that i could quickly and easily clean it out whereas a new erg filter costs a hundred dollars or more. I bought two bottles of Seafoam Motor treatment because its an add on item and that way i could get the discounted price without adding anything on. For my purposes I found it easiest to pour the seafoam into the hose that attaches to the auxiliary air valve as this was easy to remove and fed right into the junction past the Mass airflow sensor. The brake booster would have been more troublesome despite many people recommending it. I Believe you should just look at all the air hoses leading into the manifold of your car and choose which both won't change the way the engine runs and is easy to pour into which in many cases is the brake booster hose. I warmed up the engine so the auxiliary air valve would not be needed for engine operation, and then I had to cover the majority of the open and exposed end of the hose so the engine would not be choked by too much air, then Its a matter of putting the right amount of Seafoam in so that you don't choke it that way either. At this point you will begin seeing white smoke come out of the exhaust. This is a sign that the seafoam is burning and working properly so continue until you've used nearly a third of the bottle. I actually had trouble killing the engine at the end when you are supposed to pour enough in to kill it so I just shut off the ignition after dumping a lot in at the end. I waited about 10 minutes for it to all soak in and then restarted the engine. I let it run for a little and then began a slow drive around the neighborhood in a low gear to run the engine quickly but not too fast. This created the most smoke by far which is good because that meant it soaked well. Once the smoke stopped or slowed significantly I shut the engine off and checked in the ERG valve hole on the manifold once the engine cooled. I Could not find any more of the greasy black gunk so It worked! The rest was split between going into the fuel and the oil to clean out injectors and galleys and I plan on an oil change soon as a result. Great product does what it says it does and my engine is running much smoother now likely due to a more even mixture in a no longer impacted manifold. I also recommend watching a youtube video on how to do this, it helps to see the things I'm talking about.

### ⭐⭐⭐⭐⭐ Good product.  Great price.

Been using it for years on my 100% gas and diesel. Never have a problem. Cheap insurance.

### ⭐⭐⭐⭐⭐ Good product
*by M***T on June 2, 2025*

Good product. Can clean your engine while you drive, also will clean your fuel injectors. In the gallon size, it’s more economical than buying the pints. Also can help stabilize fuel for long term storage.
