Been looking for an oil to use as double duty daily/HPDE oil in my C5 Corvette and have been going down the oil rabbit hole.
Was kind of leaning towards M1 0w40FS but then read that the high calcium could "compete" with the ZDDP so I didn't pull the trigger just yet on the oil. Currently running 5w30EDGE Dexos.
Saw that now the 0w40FS is SP rated, does that mean it will have lower calcium for the DI LSPI "issues"?
Went to the local wal mart and they still have SN bottles only.
