VW's 3rd generation 1.8T engine has a sump capacity of 6.7 qts vs 4.4 qts for the larger, more powerful 2.0T. These engines appear to have identical architecture, so it is puzzling to see such a big difference in oil capacity. For both engines synthetic oil (VW 502 spec) is required and a 10K oil change interval is recommended.
Why is there such a big difference, and in the wrong direction? It's as if the sludge lawsuit a decade ago with the 1st generation 1.8T scared VW into enlarging the sump capacity to extremes. But why not on the 2.0T as well? Surely there must be a more technical reason. Any ideas?
