Thanks for the question!

For your Cadillac, I’d recommend using High Mileage Sea Foam for its extra cleaning strength.

You can add a full can to a full tank, but if your goal is cleaning, I’d recommend waiting until you have about 1/4 tank or less and adding a full 16 oz can of High Mileage. The higher concentration will work much better and faster to clean fuel gum and varnish deposits from the fuel injectors and fuel system.

After adding High Mileage, drive at least 10–20 miles before refueling to give the higher concentration time to work.

Thanks for the question!

I’d recommend Sea Foam Motor Treatment for your Ariens snowblower. It’s safe for small gasoline engines and works great for keeping the carburetor and fuel system clean.

For regular preventative maintenance, add about 2 oz of Sea Foam per gallon of gasoline. There’s no need to measure exactly.

Sea Foam will help prevent fuel gum and varnish from forming, which is especially important for seasonal equipment like snowblowers. It also helps stabilize fuel during storage.

If you’re trying to clean a gummed-up carburetor or fix a running problem, you can use a much higher concentration for cleaning (a 1:2 ratio of Sea Foam to fuel).

Hi Paul,

Thanks for the question! At a minimum, add 2 ounces per gallon of gas for storage. That will prevent fuel residues and varnish from forming while it’s in storage. You could also add the entire 16 oz can if you want to use a high cleaning concentration in addition to getting it ready for storage. The high concentration will do a good job cleaning up any gum and varnish when you run through that tank of gas next season. It’s a great way to get the most out of a can of Sea Foam.

Either way, make sure you run the motorcycle for 10-15 minutes to make sure the treated fuel makes it through the entire fuel system.

Hi Rick,

Thanks for the question!

Yes, you’re on the right track! For your new Husqvarna snowblower, I’d recommend using about 1–2 oz of Sea Foam Motor Treatment per gallon of gasoline for regular preventative maintenance.

Here’s what I’d do: simply eyeball 1-2 oz of Sea Foam every time you fill up the snowblower tank. There’s no need to measure it exactly. You can safely add a lot of Sea Foam to gas. For example, while it’s unnecessary to add this much for regular preventative maintenance, it’s possible to use up to a 1:2 ratio of Sea Foam to gas for a strong cleaning dose. So don’t worry about using too much or being precise. Make it easy for yourself and just pour some in.

Sea Foam will help keep the carburetor and fuel system clean and prevent fuel gum and varnish from forming, which is especially important for seasonal equipment like snowblowers.

It will also help stabilize the fuel during storage. Just make sure to run the engine for a few minutes after adding treated fuel so it circulates throughout the fuel system.

Alternatively, if you keep gas in a gas can in your garage, just dump 1-2 oz of Sea Foam per gallon of gas into the gas can and you’re good to go.

• Wait until you have about 1 gallon of gasoline left in the tank.
• Add a full 16 oz can of Sea Foam High Mileage.
• Start the engine and let it run for several minutes so the treated fuel reaches both carburetors.
• Shut it off and let it soak overnight.
• The next day, start the engine and ride normally to continue cleaning.
