I'll try that next oil change. That stuff isn't inexpensive. Less expensive than tensioners. Still.

I don’t remember it being terrible. I bought a big 2.5 gallon/10 quart jug for $50.

Edit: just checked and Walmart still has them for $49.97...not much different than Mobil1.

If its chain rattle,.(.which mine does once after the 1st start) ,..why dos'nt it do it everytime you start the car if the internal parts were bad or maybe worn a little it should kinda always do it,.but if its only the 1st start should it not be the tensioner's because they have time to bleed off or maybe the oil is a little to thin..?? Its just annoying

Not only the tensioner's bleeding off.
But also the lifters bleeding down over time.
A little tensioner pad wear, a little chain stretch, a little this a little that and you have slack in the chains.
Start the car, oil pressure pumps everything back up. No noise tell everything bleeds down again.
