IF someone had a new vechile with no build up could Auto-RX be used as a preventive additive in the engine and trany? Could someone add 3 ounces to the engine oil each change and maybe 3 ounces every 15,000 miles to the trany fluid to keep everything clean or wold this negatively impact durability. I ask because I am all about preventive maintence. I would rather not allow the buildup in the engine and trans then have to try to get it out. Seeing how most of my experince with cars seems to always lead to or from a seal failure would this type of treatment prevent any seal hardening from ever happening? Thanks Frank. P.S. I have noticed a huge difference in my transmission with just a 150miles since I put the Auto-Rx in. I have not noticed much with the engine and the oil seems to be pretty clean still but we will see at 500! I used the cheapest oil I could find(walmart Tech2000 10W30) to make sure that their are no ester's in it.
