Mark,
It's called mass marketing. They make a gazillion quarts of 10W40 oil to a
few dozen quarts of MT90 oil, by comparasion. And just a note, I paid $2.62 a
quart for Castrol 10W40 a few weeks ago at Wal Mart.

Now I'm really confusered.
So why did I just put $7.00/qt MT90 in my trany instead of $1.40 10/40.
Hmmm?
Thanks Guys, Mark
