I just purchased a rs/6 with 19k miles on it. I am looking to purchase case or cases of the castrol 505 01 oil. Questions is this the recomended oil for my baby, does anyone sell it by the case? Another question I have is the 0-60 time I was told is 4.2 without the chip. Yet, I reading in this forum that with a chip it is 4.3 on a cold day. What is the stock number? It feels sooooo much faster than my gs400 which does the 5.7.

 

the rs6 was claimed to be 0-60 in 4.6 by audi. But in various tests by european car, road and track, etc. ive seen it tested as 4.5 Yeah this thing is FAST!!!! As for the oil im not sure what kinda is recommended. Just make sure ur using synthetic obviously.

 

dont use syntec oil. better to invest extra buck in true syntetic oil like mobil1.
