I've been doing a bit of reading on A5/B5 oils on Lubrizol's website and how A5/B5 may meet Ford WSS-M2C913-C.
Having contacted an oil company a few years ago, I was told WSS-M2C913-C is Ford's brand name for the ILSAC GF-4 specification. Which has me wondering, can an A5/B5 lubricant be used in an application calling for ILSAC GF-4 or 5? How do these two specs compare?
