It's that time, time for an oil change. For the longevity of engine power and health, it seems that using an oil that has lower NOACK volatility will reduce the oil vapors going back through the intake and baking on to the intake ports.
I kinda remember seeing a comparison of the NOACK volatility scores of different RS-spec compatible oils. I think there was even a bar graph. I can't seem to find it though, anyone have that handy, if I didn't just dream it up? And I'm having trouble even finding any number just for the Motorcraft XO-5w50-QGT stuff. Is there any test result available just for the Motorcraft one?
Is there a consensus on low volatility oils and reducing carbon buildup on the intake of direct injection engines, or is it not worth thinking about?
