The first 3 years I owned this 3.2 I used Brad Penn 20W50 with an oil consumption of 1200miles/qt. Next I switched to Valvoline VR1 20W50 and consumption dropped to about 1750miles/qt. This year switching to Liqui Moly Touring High Tech 20W50 and having driven about 600 miles I do not see any appreciable oil usage, even though as miles build up it is natural to expect some oil consumption, but no doubt this reduction is notable. And the engine purrs beautifully!
I also use Liqui Moly MoS2, but I used that along with the previous oil brands.
