This is my go-to heavy 5W30 synthetic
Quote
Castrol Edge 5W30 A3/B4 Full Synthetic
It's rated API SL (high ZDDP, but passes all SN tests), ACEA A3/B4, MB 229.5, BMW LL-01 and VW 502/505.
Noack volatility below 10%, Zinc around 1000 ppm, HTHS = 3.6 cP, KV100 = 11.9 cSt, SA = 1.2%, TBN = 10.2 and PP = -45C
