Hello peeps, could someone please explain whether Noack volatility is more important than Viscosity Index ?
I am comparing three 913D oils, Liqui Moly Special Tec F, Motul Specific 913D and Ravenol FDS, all 5w30 ACEA A5/B5 oils and trying to figure out which one is the best. So far I was with Ravenol because apart from the 913 spec, has also the MB 229.6 which seems extra protective for the engine + a Noack of 8.9. However, it has a VI of "only" 163, where in comparison Liqui Moly has 171 but a Noack of 12%. Please unravel the mystery for me
