Skip Seafoam... stick w/ Techron and do it a tank or two before next oil change... *NM*

My car is running fine but I was thinking of buying a fuel cleaner.

Sometimes I will buy Techron and came across this deal of B1G1 Free :
Techron


Then I read a post about Seafoam and was surprised by the phenominal reviews:.
Seafoam


Is there a downside to using this product?

Thanks in advance.

decades of SAE papers behind it.

In general, i dont use much of anything, but if i do, i use techron.

If seafoam does have actual, peer-reviewed stuidies, i'd like to see them.
