Then try with ACEA C3 or its derivates (VW 504/507....MB 229.51....BMW LL-04)Because an A3/B4 xW30 is incredible hard to come by where I am; xxW30 or xW30 usually come in A5/B5 flavours only.
So for the past three or four oil changes I have swapped over to a 0W40 or 5W40 (both A3/B4) instead. Thinking about dropping back to the xW30, and wondering if an w30 A5/B5 would be suitable given initially, the car manual has only said “10W30 API SJ” and nothing else.
Tell me if I’m sweating out over nothing at all! Haha.
HTHS of 3.5min....low/mid saps...and in 0w30 or 5w30 grade only...
