Hi. I have a 2006 Audi A3, which needs the Acea A3/B4 spec oil. Where I live, it gets to -5 degrees below zero in the Winter, and 90 degrees Farenheit in the summer in the north east US.
So cold flow is important. I watched some cold flow tests on youtube, where the oil is frozen for 24 hours at below 0 degrees Farenheit and then they test how well it flows. Unfortunately the Castrol Edge ACEA A3/B4 5W-30 in 5 quart jug from Walmart for $27 (which I was almost deciding on using)
was very slow flowing compared to the other oils.
I would rather go with A3/B4 rather than C3 due to A3/B4's higher phosphorus anti-wear additive.
I'd also rather stay with a 30 weight oil if possible for greater flow in cold weather.
Would anyone know if there is anything in the Acea A3/B4 spec regarding cold weather flow?
Also, which Acea A3/B4 oil would you recommend for below 0 degrees Farenheit winters?.
Thanks
