Hi Bob,
I think that it is all the media's fault. O'l man television has got us. It
is they who have taught is to worry about EVERYTHING. They tell us that
the planet is warming. They tell us that the Chinese will overtake us soon.
They tell us that the value of the dollar is dropping. And now all of the US
nuclear plants are going to kill us too. They tell us that the price of
oil is skyrocketing. Worry Worry. It's a wonder that we can barely get thru
the day as it is.
Please see below.
Regards,
Bob Helt

Neat chart, Bob, it provides the plain-spoken guide I was seeking.
Thank you for sharing it.
Maybe you should buy a couple of my books and get caught up on things.
Now, to ensure that I understand it correctly, I have grabbed a bottle
of Quaker State 10w-40 that I purchased only a few days ago for use in
my wife's modern car.
Starburst on the front? No.
Two-letter designation at the top of the donut? Not quite. The top
half of the donut reads API SERVICE SN, so if what you mean is that the
two-letter designation should be at the 12-o'clock position, it isn't.
But if what you mean is that the designation should be in the top
portion of the donut, it is.
Hey, the top as opposed to the bottom.
But I wonder just WHY you are planning to use that oil in a MODERN CAR?
Any modern car SHOULD be using oil with the Starburst.
Do we need another diagram for that?
Since the two-letter designation is SN, does it say ENERGY CONSERVING or
RESOURCE CONSERVING at the bottom of the donut? No -- the bottom of the
donut is blank.
So I reach the "OK to use" box. Correct?
Correct
Next I grabbed the only other oil currently in the garage, a lone bottle
of Shell Rotella T 15w-40.
Starburst on the front? No.
Two-letter designation at the top of the donut? Here again, it is the
top half of the donut, reading API SERVICE CJ-4/SM.
Since the two-letter designation includes SM, does it say ENERGY
CONSERVING or RESOURCE CONSERVING at the bottom of the donut? No -- the
bottom of the donut is blank.
So again I reach the "OK to use" box. Correct?
correct
Now, Bob, what about the carryings-on about zinc and phosphorous and
things not in modern oils that ought to be in our old cars? Does the
guidance provided by your chart mean that I can not worry about this?
Or should I still seek out the oils that claim to have higher levels of
these ingredients and/or are marketed to the collector car crowd? Or
should I add something like ZDDP Plus or Cam-shield?
Worry, worry, worry. You are sure welcome to continue worrying. But the
chart should keep you pretty safe. Of course you could worry that the
required amount of Phosphorus really isn't defined for flat lifter cars. (oh no!)
It is thought to be somewhere between 1000ppm and 1800ppm. But what is the
"right" number? And too much is said to be bad too. How much is too much?
More stuff to worry about.
And how much zinc is required anyhow? The "stupid" API has failed to
specify how much zinc should be in our oils. What is the matter with them
anyhow? Don't they know we need to know this or that we will worry ourselves to
death? What if the amount of zinc isn't sufficient? What if it is too much?
(You do know, don't you, that zinc is NOT an API specified ingredient in
oil?)
Anyhow, thanks for the chance to poke a little fun at the subject.
Regards,
Bob Helt
