Bob,
Still looking but I did find this:
FormulaShellTM Motor Oils
SAE 5W-30, 10W-30, 10W-40, 20W-50, 30 and 40
The FormulaShellTM range of motor oils offer exceptional protection
for vehicles powered by gasoline, LPG or CNG, including passenger
cars, pickup trucks and vans.
The FormulaShellTM family of multigrade and single grade motor oils
cover a range of SAE viscosity grades, 5W-30, 10W-30, 10W-40, 20W-50,
SAE 30 and SAE 40. The domestic automobile manufacturers general
recommend the 5W-30 grade for all-season use in late-model 4- and
small 6 cylinder engines, whereas the 10W-30 grade is preferred for
some larger 6-cylinder and V-8 gasoline engines and for turbocharged
models. The SAE 10W-40 grade is still popular with consumers although
it is not recommended by Chrysler, Ford or General Motors for use in
their recent model engines. Some European vehicle manufacturers,
however, recommend the 10W-40 grade, particularly for high temperature
operation. The 20W-50 grade is designed for severe service in high
summer temperatures, particularly in European vehicles. The SAE 30 and
SAE 40 grade oils may be used in certain temperature conditions, where
they deliver excellent protection. Always refer to the vehicle's
manual for the manufacturer's recommendations regarding the correct
viscosity grade and performance levels required for proper lubrication
of a particular engine.
FormulaShellTM Multigrade and Single grade motor oils are formulated
with powerful additive systems designed especially for the new API SJ,
Energy Conserving and ILSAC GF-2 performance requirements and offer
the following benefits:
superior protection against engine wear under demanding service
outstanding control of oil thickening and oxidation in hot conditions
excellent abilities to keep engines clean
The new ILSAC GF-2 and API SJ specifications represent new levels of
performance, including fuel efficiency in today's low friction
engines, lower phosphorus levels for emission system durability, new
low-temperature flowability requirements and new high temperature
deposit test requirements to ensure turbocharger cleanliness. All the
FormulaShellTM Motor Oils exceed the API SJ classification
requirements and can be used where the previous service
classifications API SH, SG or SF were recommended. In addition, the
5W-30 and 10W-30 grades exceed the Energy Conserving II requirements
and the ILSAC GF-2 specification. There grades can be used where the
previous ILSAC GF-1 specification was recommended. For applications in
diesel engines, such as API CD (obsolete), API CF-4 or API CG-4, the
appropriate viscosity of the ROTELLA T oils is recommended.

Jim
