Hey guys, Been on this forum for a while now and with all the recent reformulations of some of the best oils, I'm now looking for suggestions as to what to put in my '04 Audi S4. The owners manual specs 5w-30 but most dealers fill with 5w-40. I'm just looking for a readily available high quality synthetic that is not crazy in pricing. Since the car requires 12 quarts of oil and a $40 oil filter each time I want to change the oil, I'm just trying to get the most for my money at this point. In the past I have noticed the engine to be rather loud with the castrol 5w-40 as well as the Mobil 1 TDT fill and have recently been running PP 5w30. I like the oil but am experiencing some oil consumption with this oil. Just looking for some recomendations as I've been out of the loop for a while now. Any suggestions would be greatly appreciated.
