Drove new Ram 1500 truck towing auto trailer on back to Spokane from Oregon to pick up a car and trailer it home. Poured this into the engine (hemi) prior to leaving on the trip. Prior to using I was getting 21.8 miles per gallon and after putting it in the engine and even while towing a trailer (empty trailer) it jumped to 22.7. I was shocked. On the way back (with car on trailer) I got 16.1 mpg and was very pleased. The truck had 15,400.2 miles on it when the Nano Prime was installed. (yes, it's a 2016 truck) Synthetic Mobile on extended oil and K&N oil filter, K&N air filter as well. 89 Octane. Totally pleased. Yes, it works. I also have used Slick 50 back in the 80's, Duralube in the 90's, Z-max in the 2000's. Motorkote in 2010, and now. Rislone Nano. It works ! I'm going to be putting it into all of my vehicles.
