PS: all these oil additive commercials about cold-start wear and increased gas mileage/horsepower are ALL snake oil products. Your car is not going to make more power than it came with from the factory because of something you pour somewhere into your motor. All that some of these products will do is restore power that has been lost due to another problem... and usually won't even restore all of it. If you get an extra 10 miles per tank of gas, so what. Your Honda will go that far on about 55¢ worth of gas. How much is that product?
Teflon and PTE are heavier than oil. They sludge in your oil pan and clog oil passages. This kills engines. No oil additives, period.
