Has anyone who has used this product (spraying in through air intake) performed a before and after compression test? Did it achieve noticeable gains? I am not ordinarily a fan of mechanics in a can, but have used a couple to quiet lifters and I used to use Mystery oil in the fuel and oil of my older rigs.
Oddly enough, I can't get SeaFoam or Mystery oil here. Last trip I had Mystery oil seized from my checked luggage by TSA as well. It was triple packaged for spill proof integrity. Amazon won't mail it to a military post office. Never knew Mystery oil was sinister. Mystery to me.
