We are not able to join the forums, but we can give you the answer you need, or
maybe would like to add to the forum. Our VR1 Racing Oil is NOT just an
"ordinary new car street oil" as listed. Our Valvoline VR1 Racing Oils can be
used in street applications, but still contains the high amount of ZDDP (Zinc
and Phosphorus). This information can be found on our Valvoline.com website,
under the section where it lists the Racing Oils. We have also added the product
information sheet for both the VR1 and the "Not Street Legal" Racing oils. As
you will see, Valvoline still contains 1200 ppm Zinc content in our regular
conventional VR1. It does carry the API Service "SM" rating, but this oil was
not made to change for emission standards due to it not being a "ordinary street
car oil." This information clearly states the amount of both the Zinc and
Phosphorus levels in the oils. The main difference between the the "Not Street
Legal" racing oil, or commonly known as Conventional and Synthetic Racing oils,
and the VR1 is the Calcium content. Calcium levels are higher in the NSL oils,
compared to the VR1, and the NSL oil is only recommended for 500 mile oil
changes, while the VR1 is a 3 month/3,000 mile oil.
Valvoline stands behind the flat-tappet and more aggressive type cam
applications 100% with our Valvoline VR1 and NSL Racing oils. The proof is in
our product information sheets, which are online for the viewing as well.
Here are the product information sheets with test results for all of VR1, Not
Street Legal conventional, and Not Street Legal Synthetic.
Thank you,
Valvoline
Adding to what we stated earlier, we have read throughout the forum. We see a
lot of references to the API Service "SM" rating, being the main cause for
catalytic converter damage. SM is basically just a gasoline rating. The S stands
for Spark ignition, which refers to the ignition for gasoline type vehicles.
When an oil has an SM rating, that just plainly means that the oil past the
specific API (American Petroleum Institute) test requirements to obtain this
specification. It has nothing to do with catalytic converters. The rating that
stands out on conventional motor oils, (Premium conventional, Durablend, &
Synpower) is the GF-3 and GF-4 ratings. These are energy conserving ratings that
are necessary because of the Environmental Protection Agency mandating federal
standards to further reduce emissions, beginning with '05 vehicles. These are
the ratings that make the oil safe for catalyst effectiveness, and these ratings
are not found on the VR1 Racing Oils due the ZDDP additive content, not API
Service "SM."
Hope this helps,
Valvoline

Please respond to this post from the Corvette forum. I have been using Not
Street Legal Racing Oil because of the higher Zn and P content. Your web
site shows VR1 has as much or more of these ingredients. However, the
forum poster, who I quote, says your web site info is wrong. Please let me
know.

whats suspect? are you saying you do not believe the these specs "zinc/phos
.130/.120" what do you base your comments on?
If you've been following along, you'd know that API SM rated oils are the
ones with the lowest zinc/phos levels to protect the cats on modern cars.
Makes no sense to claim race oil levels of zinc in a given oil, when it has
the SM rating. They are mutually exclusive. It would be magic for this to
be the only oil with such high zinc, yet not destroy cats like other oils
would with similar amounts of zinc. Valvoline's other Racing Oils that are
shown with even less zinc, have warnings that they are not street legal,
and can destroy cats if used in street cars. So, if VR1 had that much zinc,
it would also need the same warnings, but it doesn't have them. It couldn't
be street legal API SM oil with a ton of zinc in it. If you look at the
link above, you'll see that 2 independent UOA tests showed it having less
than average zinc/phos, not more, as the Valvoline spec shows. So, no I do
not believe Valvoline's published specs. I'd like to think it was just an
honest misprint on their part."
Please E-Mail me so I can share with my fellow Corvette owners.
Thanks,

The oil industry per ILSAC had to only decrease the levels of ZDDP (Zinc)
in certain viscosity to meet new emission standards. The ILSAC rated oils
still have an average of .085 levels of zinc. Testing has shown on standard
OEM set ups that used mild camshafts will still get plenty of protection
from the new rated oils. There is an exception when it comes to extreme
aftermarket applications. If you have a high performance solid lifter set
up with an aggressive cam then you will need to use a quality Racing Oil
such as VR1 or All Fleet Plus Oil for break in and normal usage. These oils
have an increased level of Zinc that will range from .14 to .16 and will
provide plenty of protection. QUOTE:
