Engine rattle

Next on the list toward perfection....

When ultramatic shifts from 1st to 2nd, I will often hear an engine rattle. Here's my best impression....

Say, "Glug, glug, glug, glug, glug, glug" real fast. Now, add a twinge of "metally" sound to it.

It sounds kind of like what I have heard referenced as "ping" but doesn't really "ping" to my ears. There is no high pitch. It's more of a rattle.

Mechanic says probably because lead is missing in gas these days and lead used to serve as a lubricant.

I read earlier on this forum about possibe, toxic additives. Frankly, if that's all there is to it, I'll pass on the additives. As much as I drive, that would sure up the cost big-time.

Am I on track here?
