I wrote to Vavoline about ZDDP content in their "off road" racing oil. Now on their oil cans it reads with ZDDP on a bright label on the VR-1 racing oil cans. Also about the additives to oil... Vavoline racing oils far exceedes any oil requirements and those reported "super Nano lubricantes" just burn off within 100 miles. The Vavoline oil is blended not to break down in extreme heat or cold. For our 235 they recommended 10-30 wt....if you have questions Vavoline will give you an answer via email....just go to their website.
