I put about half of a bottle into my contour. This was before I knew that my sending unit was terribly off. It REALLY helps for me. My cooling fan only turns on if im sitting for a fair amount of time. Normally if Im going arround town as long as the car is moving at about 35MPH its between the R and the M. But if I sit for a while it goes up to the L and the fan kicks on for about 15 seconds. Its a nice relief to know that I dont have to run the AC, I hate running the AC with a stick, the drive gets a little more rough.
