NanoLub RCX Engine Oil Additive 250 ml Bottle

Used it in 3 vehicles and every day thereafter all the engines run quieter and each of them accelerate smoother and with more power. Been telling everyone I meet about it but unless they try it they will never know. Gave a bottle to brother-in-law and after one week he talked me into selling him another extra bottle I had on hand for his other car. The vehicles are 1998 Malibu, 2005 express van 3500 and 2014 Scion XB. Oil pressure in the 6 liter express van seems to be going up with time as the bearing surfaces buildup exfoliated layers of Tungsten Disulfide.

This product increased gas mileage, quieted both engines, and instead of filling up once a week with gasoline, it is now every 14-16 days. For us, this stuff is a real money saver!
