Review on Camco 40246 TST Drain Valve Lube with Coco Oil - 16 oz: Enhanced Lubrication for Efficient Drain Valve Performance by Carlos Jass

It was cheap to try out, but I wouldn't buy it again. I have read and strictly followed all instructions. My accumulator valves are sticking a bit. As instructed, I emptied both tanks, added the product and the recommended amount of water, drove the van around to mix it, then opened/closed the valve as instructed. I couldn't tell any difference in the function of the values or the ease of opening or closing. In fact, I've had MUCH more meaningful results by simply using the oil that penetrates the spray and spraying the cable from both ends (at the valve and the handle). This brought a significant improvement. I will throw the remaining product in the bin to use up, but I wouldn't buy it again.
