Bests & Worsts Reviews from Amazon

I don’t see why these people are giving a 1 star rating. I have been a mechanic for over 30 years. I have a 2006 Jeep Wrangler with 178,000 miles on it. I added this product and I noticed differences right away. I live in a mountainous area and since using this product my shifting and engine RPM pattern has been way different. Hills that I used to have to downshift on are a thing of the past. I feel this product took my engine back to 78,000 miles instead of it having 178,000 miles. I am really tempted to use it in my transmission, transfer case and differentials. I wish I knew someone that had a high mileage vehicle that vislabaly burnt oil to try this product in to see if and how this product worked on it.
