These three things are usually included in
a doughnut shaped logo (symbol) on most
containers. If you cannot find oils with
the “starburst” symbol, you should look
for oils with the doughnut shaped symbol,
containing the three things noted above.

If you use oils that do not have
either the “starburst” symbol or an
API SH designation, you can cause
engine damage not covered by your
warranty.
