Just curious about the value of having low volatility numbers on an oil. Does an oil with low volatility numbers mean that it might burn less than an oil with higher volatility numbers when used in the same engine. I've been looking for an oil with low numbers, but just curious if this is a worthwhile feature of an oil. My thinking is that low volatility might mean lower chance of oil rings being stuck over time. Not sure if this is correct or not though. any info appreciated, thanks.
