Jeremy
Just to add some options or confusion to the answer to your questions
~ this is from a couple of posts I made back in Nov'12 ~
I just reread the LubricationSpecs in the OwnersManuals of both
my 83.5 & 90 Westys & in fact in the SingleWeight columns SAE50 is not
even mentioned ~ SAE40 is the recommended Oil for Temps from 70º on up
off the end of the chart. SAE **w-50 is indicated in the MultiGrade
columns but shares the Temp'Range with SAE **w-40. SAE10, 5w-30 &
5w-20 are even recommended under certain conditions. Certainly in an
OldEngine there might be a need to run SAE50 under some Temp'
conditions but I would let my OilPressure be my guide not necessarily
a manual that was written 22 - 29yrs ago. I would run nothing but 0w40
in my H2OBoxr if Valvoline made it but the thinest they go is 5w40 so
that works for me. I know that Mobil1 comes in 0w40 but I just did an
unscientific 3000mi test of Mob1 0w30 in my 90Westys EJ25 &
experienced some goofy O'P's so I won't ever use or recommend Mobil1
again.
In your research you should put Valvoline on your list ( I
don't work
for them ~ Just like their stuff )
2 main points
1. Longer-Lasting Zinc/Phosphorus: Valvoline uses an advanced zinc/
phosphorus additive that keeps higher levels of phosphorus in the
motor oil where it protects the engine instead of poisoning the
catalytic converter. Valvoline is the only brand offering this unique
additive across its entire line of passenger car motor oils including
SynPower -- the only synthetic oil that offers this additive.
2. The anti-wear additive simply referred to as zinc by most car
enthusiasts is actually short for Zinc DialkylDithiophosphates or
ZDDP. Its primary role is to prevent metal-to-metal contact between
engine parts by forming a protective film. Despite being referred to
as zinc, this additive actually contains zinc and phosphorus, with
phosphorus performing the anti-wear function in the motor oil with zinc.

15. How does Valvoline's SynPower formula protect against wear?
SynPower full synthetic motor oil is formulated with a balance of high
quality ingredients such as detergents, dispersants, antioxidants,
friction modifiers, anti-wear additives and premium base oils that
work together to provide exceptional protection against engine stress
and wear.
Valvoline's proprietary formulation includes special anti-wear
chemistry. Valvoline's low impact ZDDP allows phosphorus in the anti-
wear additive to stay in the oil longer than other leading synthetic
motor oils. Phosphorous bonds to metal parts in the engine to form a
"sacrificial" layer that helps protect against friction and metal wear
in the engine.
SynPower uses premium detergents and dispersants that protect
against deposits and sludge to keep engines clean. SynPower's premium
full synthetic base oils and additives hold up to extreme temperatures
to provide increased protection for your engine.

2. What is motor oil with zinc?
The anti-wear additive simply referred to as zinc by most car
enthusiasts is actually short for Zinc DialkylDithiophosphates or
ZDDP. Its primary role is to prevent metal-to-metal contact between
engine parts by forming a protective film. Despite being referred to
as zinc, this additive actually contains zinc and phosphorus, with
phosphorus performing the anti-wear function in the motor oil with zinc.
3. Why is it important to have the zinc/phosphorus levels in
motor oil
changed?
With ever increasing limits on emissions, automobile manufacturers
have tightened emission control systems on newer vehicles. This is one
of several factors considered when the American Petroleum Institute
(API) sets standards for motor oil with zinc. The current API standard
is SM which replaced the previous SL classification. Because
phosphorus can poison a vehicle's emission system, the level of zinc
is lower for current motor oil.
4. What is the controversy surrounding the amount of zinc in
motor oil?
Many hands-on car enthusiasts and engine experts believe the lower
levels of zinc in SM motor oil is causing excessive wear in older
style push-rod and flat-tappet engines. This is despite the fact that
all new motor oil classifications are intended to be backward
compatible. This has resulted in the widely accepted belief that
modern motor oil is not adequate to protect older engines.
5. What solutions does Valvoline offer to the zinc issue?
Valvoline offers two solutions to the zinc issue:
1. Valvoline VR1 Racing Oil: Contains 75% higher zinc than SM motor
oil with a balanced additive package designed to work in both racing
and street-legal applications. This product will protect older style
push-rod and flat tappet engines. Valvoline provides this product in
both multi and mono viscosity grades: 20w50, straight 50, 10w30,
straight 30, straight 40, and straight 60.
2. Longer-Lasting Zinc/Phosphorus: Valvoline uses an advanced zinc/
phosphorus additive that keeps higher levels of phosphorus in the
motor oil where it protects the engine instead of poisoning the
catalytic converter. Valvoline is the only brand offering this unique
additive across its entire line of passenger car motor oils including
SynPower -- the only synthetic oil that offers this additive.
6. Which oil has more zinc/ZDDP: VR1 or "Not Street Legal" racing
oil?
Valvoline VR1 Racing Oil contains .13 percent of zinc and .12 percent
of phosphorus compared to the Valvoline "Not Street Legal" Racing Oil
which contains .14 percent of zinc and .13 percent of phosphorus.

PS ~ as far as filters go ~ I use Wix ~ claimed by a lot of folks to
be the best ~ I get them from NAPA in the form of NAPA Gold ~ have
used them on all my cars for a lot of years with no complaints ~ there
have been some times that I have used the higher end Frams & have
never had a problem with them either.
