Hey guys. What are your thoughts on Seafoam? Do you run it in your personal vehicles or just equipment? I have read about it a lot and hear some great things about it. What are the downsides? Would you add it to the oil or just the fuel? or both? I was going to start using it for my wifes car and my explorer. Both are at 80-90k miles. I want to start doing more to prevent any major issues from happening. I would rather plan on spending $10 then having to pay out $8 unexpectedly.
