3 cans of BG EPR Engine Performance Restoration

Used this on multiple cars. 2016 Nissan Murano with 60K, 2000 Nissan Altima with 200K, 2003 Nissan 350Z with 90K, and 2018 Acura TLX with 140K. For all cars, performed an oil and filter change with Supertech oil and filters from Walmart. With the oil change, added the BG solution and ran cars at 1200 RPM for 20-30 minutes on each car as directed (label says run for at least 10 minutes). After running the BG solution, performed another oil change using a new Supertech filter and oil. Ran the cars for 100 miles and then performed a final oil change using my preferred oil and filter on each car. All cars have been regularly maintained, and during the oil changes performing this flush, did not see the oil come out dirtier than expected. Even after the 20-30 minute runtime, the oil came out fairly clean on all cars. Only thing noticeable was the smell of the BG product and that the first oil change came out thinner. The only car I was able to validate that something happened was on the 350Z. This car has an oil pressure gauge, and I did notice that the pressure went up a little. The needle was a little higher than it had normally been. This is an indication that this product restored some compression. I will assume this did it on the other cars as well. The only other thing that I have noticed is that the oil is staying cleaner longer after an oil change on all cars. Other than that I cannot say that performance is better, or that fuel economy is better (pretty much has stayed the same). However, I do believe it cleaned as it was supposed to because of the two things I can report on. Oil is cleaner longer, and the pressure on the 350Z increased. I will probably continue to use this as a preventative maintenance every 60K or so. All cars are in good condition, none of them had any leaks or other problems. I was not trying to fix anything with this product. It seems some people are trying to fix issues by using this, and at that point it may not work. Only thing I can see this helping is possibly oil consumption. On the 2000 Altima this has 200K miles on it, but all seals and gaskets are intact. There was no seepage anywhere prior to using this. None of these cars blew up, and no oil leaks have sprung up on any of these cars. I figure the Altima would be the one to develop any problems after using this at such a high mileage, but only after effect is the oil is staying cleaner longer (Not thousands of miles longer, but after a fresh oil change the oil stays looking newer longer than it used to). This applies to all the rest of the vehicles as well.
