What are the thickest 30 weights oils?
Thickest current Resource Conserving (ILSAC GF-5) oils I'm aware of are Amsoil OE and XL 5w30 with HTHS of 3.3 cSt.
Thickest non-RC oils are the high mileage and Euro varieties like Dennis said. A Non-exhaustive list:
Valvoline Maxlife Full Synthetic
Valvoline Synpower MST 5w30
Mobil 1 High Mileage 10w30
Mobil 1 ESP Formula 5w30
Castrol SLX OE
Castrol Syntec 0w30 (German Castrol)
Pennzoil Ultra Euro 5w30
