Yes. Vegetable oils have really high VI's but when mixed with other oils that have lower VI's, the resultant VI is lower.
I find it strange that RLI chooses to use VIIs in all it's multigrade formulations, even their 10W-30 with it's low VI of 153. Which leads me to conclude that the actual vegetable content is well under 50% and RLI's not using high VI PAO's but low VI GP III oils in their formulations.
