Replacing timing chain

Here's a tip I stumbled across 20 years ago when using my chainsaw and I ran out of chain/bar oil. I filled it with Redline synthetic gear oil. My chains started to last 5 times as long without stretching. I soaked my timing chain on it's side in the stuff overnight, and they virtually stopped stretching anymore after break in. It is amazingly effective actually. I've had the same result on half a dozen builds since then.
