How many millilitres of Sea Foam per litre of fuel [SOLVED]

Hey David,

Here’s our recommendation for Sea Foam in fuel, in ml and litres:

For routine/preventative maintenance:

Add 10 ml per litre of fuel. One can treats up to 47
litres. One gallon treats up to 378 litres. Just pour directly into the tank.

For cleaning: 

Add at least 20 ml per litre of fuel.

When cleaning a gasoline or diesel fuel system, it’s safe to add more Sea Foam to fuel. In fact,
the more Sea Foam you add to fuel, the greater the cleaning concentration. For best results, add a full can of Sea Foam to a low tank of fuel (1/8 tank or so), and drive at least 30 km before refueling.

Additional
Sea Foam Motor Treatment only contains petroleum-based ingredients and is always safe
to use in all types of gasoline and diesel engines. It does NOT contain harsh detergent or
abrasive chemicals.

I have a diesel ride on mower, it holds about 30L of fuel. It has been sat over the winter with a partially full tank. I topped it up to give it its first use of the year and noticed it surging like it was being starved of fuel. I changed the fuel filter as it had sediment it. How much Sea Foam do I need to put in to treat the fuel and how long do I need to run the engine for?

Thanks

Hi Kiran – thanks for the question. If you’re going to be running the tractor a lot, I’d wait until you’re at about 10L of fuel and then add a full can of Sea Foam Motor Treatment. Then, run it until almost empty. That gives the treated fuel time to work through the system, and the high concentration will do a great job cleaning anything that formed during storage.

If you aren’t planning to use up that tank of fuel soon, I’d go ahead and add a full can of Sea Foam Motor Treatment. As you run the tractor, the Sea Foam will work to clean as well as prevent additional trouble while it sits.

Hope that helps!
