Can you lay out the specs? Is this A3 HT/HS 3.5> Elf? Have you changed gasoline? **I'm convinced that the quality of gas varies greatly and impacts performance more than oils. However, if you're going from HT/HS of 3.5 to 2.8, you will notice it.
Fuel was the same tank... unchanged.
Oil seems like it is as thick as GC...so it could be my imagination...but I doubt it... or the explanation might have to do with friction modifiers?
Here's some hype and some specs:
