Best Engine oil for Audi A3

Castrol works fine.

5k or less with Liquimoly. Just had oil pan and upper timing cover replaced at 123k miles (plastic parts leak/ fail bc of heat cycles) and my timing chain looked like new, and not one spec of metal or debris on the bottom end. Unitronic stage 1+ since 75k miles.

5-6k. It depends on how much you push the car. Hard acceleration and high revs will require more frequent oil changes.

my consumption was terrible when running Castrol .... Now it's pretty decent .... Especially for winter time .... Liquimoly is ace.

It helped significantly! Went from burning Castrol to liquimoly which burns way less. Also I use a liquimoly sealer now and then to reduce consumption.

The liquimoly additive, Oil Additiv p# 8352, did help me for a bit but now it's back to the usual oil guzzling. For my choice of engine oil I use 5W-40 Toptec 4100 liquimoly .... I think it reduced consumption somewhat over OEM castrol.

I usually change the oil every 7500 miles and tend to use Castrol synthetic 0-40.

I had use both and i have driven more miles without needing to refill with motul. But motul > mobil one

2015 Audi A3, new to me a year ago. One quart every 400 miles. First car I've ever owned that consumed this much oil. It's a nightmare!

I am not hating on Amsoil. I am running their engine oil and ****ing hate it. burned off another quarter of a quart in the last day of driving... ive never had this kind of consumption before and there are no leaks...
