2.0 engine oil capacity
I was looking at the AoA site to compare specs for the 2017 A4 vs. my 2016 A6 2.0 P+ Quattro. I was surprised to see that the 2.0 engine in the 2017 A4 P+ Quattro (that to my knowledge is basically the same as he 2.0 in the 2016 A6) holds more oil (5.5 qts.) vs the A6 ( 4.9 qts). Anyone have any thoughts on why this is? Does it mean that our 2.0 engines are under-lubricated and more prone to wear?

Only if the A6 engine has a oil pump with less output. As long as the pump intake is submerged, how much oil it's submerged in doesn't matter.

Just a guess...but I don't think the difference in oil filter size would account for that much oil. My thought is there is a slight difference in the oil pan. These engines keep getting bigger and bigger oil capacities to allow better protection over the 10,000 mile oil change intervals. The engines may be similar but the new chassis provides a good opportunity for Audi to expand the size of the oil capacity for longevity of the engine. Not that the old size was bad...but the new size is better.

I am now thinking that larger oil capacity of the 2017 A4 may be related to that car's having the S-tronic transmission. The A3 2.0 engine has 6 qts. capacity and that car also has the S-tronic transmission. It may be that the Tiptronic in the A6 is just a lazier transmission and does not give the engine the high rpm workout that an S-tronic does.

That is one reason I dropped my subscription to Consumer Reports several years back. For years the Annual Auto Issue was like an almanac of wheelbase, overall length, front/rear headroom, legroom, trunk capacity in cubic feet and other useful metrics that served me well in the search for a new car every few years. I could figure out if the car I had in mind would fit in the garage, if I could fit in it and if it would hold the stuff I need to haul. Now there is little else than subjective comment – no different from most car magazines. I never relied on Consumer Reports to tell me how exciting a car was to drive, but the basic informational points I mentioned could be found there in an easily compared way. Now, there’s nothing worth knowing from this source. Today’s generation doesn’t like numbers I guess.
