Scotty,
I'm not about to replace the Motorex 10w-50 for MotorKote. I have a Honda truck with 187k miles and my wife drives a Mazda3 with 65k miles. I was thinking that this product may be helpful to improve gas mileage in those vehicles. Not replacing the oil, but using it as recommended. You'd add 8oz during an oil change mixed with 3.5 or 4qt of your favorite oil. (In my case, Mobil 1 synthetic 5W-20).
I went to the store yesterday, I saw it on the shelf, they want $30 for 16oz. I can get 4qt of Mobil 1 for $45 and sometimes cheaper. I do my own regular oil/filter changes as I use my truck for work and have to have a reliable vehicle.
Again, my question was if this product would give me better gas mileage and less wear. That's all.
