Which oil to put into my Audi?
Hello ! I have a 2005 Audi A4, 2.0 TDI (8EC, B7 - BLB engine code - PD) . Which oil should I use? I have to choose between Liqui Moly Top Tec 4100 - 5W-40 - 502.00 / 505.00 / 505.01 ------- and Liqui Moly Top Tec 4200 - 5W-30 - 504.00 / 507.00. Since I don't really know what the 5xx.yy specs are, which one should I choose?
Our answer:
Hi Darian,
Assuming your car still has its diesel particulate filter (DPF) in place, then go for the second one, as that is a low-ash oil that is suitable for use with a DPF. Otherwise, the first oil will suit.
