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.
