Talk about arrogant and condescending. Your comment is demonstrably that. Anybody can Google anything, but frankly, I don't care or need to know about Jenga because it has nothing to do with automotive additives. No one knows everything - not even you.
So that's it. You have appointed yourself to be the speech police and no negativity or skepticism is allowed, because it disturbs you..
In other words, only positive comments about SeaFoam are now welcome in this thread. So don't dare say anything other that that or you will be belittled. That's an attempt at silencing others through intimidation.
Okay...
Seafoam is the best additive ever invented. It works miracles! It increases MPG! Everyone should use it, the more frequently, the better. Never question this product or claims made about effectiveness. People who question or disagree need to be ridiculed and SILENCED!
Are you happy now?
