A couple of things here: first off - the comment was "relatively recent". Relative
to how long dino juice has been used I would presume. Since dino juice lubricated
internal combustion engines date back to at least the 1800s.... Do the math. I
would agree with Larry Shephard on this one (he wrote the book 8-). And I would
have to ask "Did you dig up your Magnum engine in your back yard?" I did say book
on Magnum engines didn't I? No more than a few years old is the printing.
Remember, this is coming from Mopar Performance - the makers of your truck - engine
and all. Remember, don't shoot (or otherwise hurt - even feelings) the messenger!

The only reference to "racing" that I saw was about the history of synthetic oil use
- moot point.

Doesn't it say that it doesn't offer any advantages if the viscosity is kept
constant? So what you are saying is that it is critical that we NOT run synthetic?
Doesn't synthetic viscosity remain constant over a wide range of temps? Considering
that the engine parts are expanding and contracting - wouldn't it help if the oil
also did the same? For example, when cold metal contracts leaving large clearances
- dino juice when cold is thickest - will fill that gap perfectly. When hot metal
expands leaving small clearances - dino juice when hot is thinnest - will fill that
gap perfectly. Isn't this basically what Larry is referring to? That could explain
the problems with scuffing. Maybe thats the sound my friends truck makes when he
first starts it up cold - using synthetic. He didnt have that problem with dino
juice.

It bores me to think that the only replies I get are attacking Larry Shephards
assertion that synthetic oils are relatively new.
