new (not really) oil from mobil 1, 0w-30 and 0w-20 - Toyota Yaris Forums

BTW castrol 0w-30 is BS 0W, given it specs more like a 10w-35. The oil does NOT have that great of cold pumpability compared, say, to Castrol Edge. The GC 0w30 is about 60,000 cSt at -40 and the Edge is about 12,000 cSt at -35. BIG difference. This engine wants a low HTHS energy conserving oil, GC is NOT - its TOO thick at 100c at 12+ cSt and its an A3/B3 not an A1/A5. Use the European spec - they make MORE sense - just like the Metric system. Look for A1/A5.
