Sea Foam in a 2008 BMW 328xi [SOLVED]

Yes! Sea Foam is safe and effective in any gas or diesel engine. You can add it to fuel or oil.

For fuel, here’s what I like to do:

Add a full can to a low tank of fuel (1/8 tank or so). Then, drive for at least 20 miles before refueling to give the Sea Foam time to work. The high cleaning concentration works very well to clean up residues and deposits. It’s one of the best ways to get the most out of a can of Sea Foam.

Hope that helps!
