I have run there products in my 03 f150 it has 200k on it. I have drove the piss out of it and it still just running just as good it did I bought it new. I haven't replaced a drivetrain parts on it and have been off roaded drove to the east and west coast pulled a 30 foot boat on long distance trips multiple times. I wouldn't run another product in any component of my vehicle. If anyone hasn't heard of bg you need to use it!!! Hands down best product out on the market!!
