How to use Sea Foam Spray in a Ford F-150 [SOLVED]

How often can I add your product through the vacuum and to add to fuel? I have a 2006 Ford F-150 5.4 L.

Thanks for the question Jeff. We do NOT recommend adding any liquid to a vacuum line, so never. Please use Sea Foam Spray to clean the upper engine. It works much better, feeds all cylinders evenly, and safe! Adding a liquid to a vacuum does not disburse well (wasteful), can risk a cylinder hydrolock and ruin the engine. For fuel, we recommend adding Sea Foam at least every 3,000 to 5,000 miles. Can add more frequent for best results.

Hey there. I am planning to add Sea Foam to my 2010 Ford F150 Lariat and was wondering if it would be ok? Just doing my research and want to make sure beforehand. I would be adding to oil and fuel.

Hi Caleb. Sea Foam is always safe to use in any fuel or oil system. It’s made from 3 petroleum cleaning and lubricating ingredients. There are NO harsh chemicals or detergents.
